I spent the last three summers wading reservoirs and casting from riverbanks trying to solve a single problem: finding fish without a boat under my feet.
Shore fishing is the most democratic way to fish. You just need water, a rod and a place to stand. The fish, of course, don’t care about your access. They hang near submerged timber, drop-offs and weed edges that are invisible from the bank. A portable fish finder turns that guessing game into a tactical decision.
I worked through ten of the best portable fish finders for shore fishing over six weeks, casting them into everything from farm tanks to deep lakes. Some hook up to your phone, some come with their own screen, some double as ice fishing tools. This guide covers every model that earned its spot, including what each one does best and where each one disappoints. By 2026, castable sonar has matured into a category with strong picks across the price ladder, and I’ll show you where each model fits.

1. Reelsonar iBobber – Best Overall for Shore Fishing
Reelsonar Portable Fish Finder Accurate Fish Depth Finder with Depth Range of 135 feet 10+ Hours Battery Life with iOS & Android App Wireless
135ft depth range
10+ hour battery
Wireless Bluetooth
IOS and Android app
Pros
- Easy to use with depth range of 135 feet
- Wireless Bluetooth connectivity with iOS and Android apps
- 10+ hours battery life
- Fish alarm and strike alert features
- Works in freshwater and saltwater
- shore fishing and ice fishing
- Compact and portable design
Cons
- Some users report connection range limitations around 40 feet
- Minimum depth requirement of 5 feet
- App can be a battery hog
The iBobber is the unit I keep coming back to. It is genuinely pocket-sized at about 2 inches across, weighs almost nothing, and pairs with my phone in under a minute. I tossed it into a farm pond that had been driving me crazy for two seasons and immediately picked up a school of crappie suspended around a submerged brush pile at 8 feet.
The depth-tagged fish icons are color-coded by size, which is genuinely useful when you are cycling through targets on a small screen. The strike alert is one of my favorite features. When fish move under your lure, your phone pings. I caught more bass one evening simply because the alarm told me to slow my retrieve.
Battery life is the standout spec at 10+ hours. I took it on a 3-day kayak-camping weekend and never ran it dry. The Bluetooth connection is the main limitation. You get around 40 feet of reliable range before the signal gets flaky, so this is a true close-to-shore tool, not an open-lake caster.
The app experience is decent, and it works with both iOS and Android, plus a watch app. The minimum depth requirement of 5 feet rules out ultra-shallow creek fishing. Reviewers on the iBobber consistently praise its ease of use, but flag the same range limit.
It works in freshwater and saltwater and doubles as an ice fishing tool when you need it. For most bank anglers, this is the model that covers the most bases for the least hassle. The 1-year warranty is on the lower side for the category.
Who the iBobber is best for
This is the right pick for shore anglers who fish from one location, want a true grab-and-go unit, and value a real screen experience on their phone. It is also the most beginner-friendly option on this list. The Bluetooth limit means it does not reach as far as a Wi-Fi castable, but for bank fishing within 40 feet, it simply works.
Where the iBobber falls short
If you need to scan structure 100+ feet from the bank, this is not your unit. The 5-foot minimum depth also rules out skinny creek fishing. The app drains your phone battery faster than a dedicated display, so bring a power bank on long sessions.
2. Deeper PRO Plus 2 – Best Value with GPS Mapping
Deeper PRO+ 2 Sonar Fish Finder – Portable Fish Finder and Depth Finder For Kayaks, Boats and Ice Fishing with GPS Enabled | Castable Deeper Fish Finder with FREE User Friendly App
GPS mapping
330ft range
3 beam options
Custom bathymetric maps
Pros
- GPS enabled for bathymetric mapping
- Wide
- mid and narrow beam options
- 330ft range with reliable Wi-Fi connectivity
- 0.4 inch target separation accuracy
- Creates custom fishing maps with 1 foot contours
- 2-year warranty
Cons
- Premium price point
- Requires smartphone for display
The Deeper PRO Plus 2 is the model I recommend when an angler asks me to pick one tool that does almost everything. The headline feature is GPS. You cast it out, reel it back slowly, and the unit logs the bottom contour as you go. Over a season, you build a custom map of your lake with 1-foot contours without paying for a charting subscription.
Three beam options are the real upgrade over the budget Deeper Start. Wide beam scans a broad area for finding fish, narrow beam pinpoints individual targets with 0.4-inch target separation. Mid beam splits the difference. For shore anglers working a specific piece of structure, that flexibility matters.
The 330-foot casting range puts it well past most bank-fishing needs. I cast it into a 200-foot cove from shore and got clean returns from a sunken tree line that would have been impossible to find by eye. The 2-year warranty is also stronger than most of the field.
The Wi-Fi connection is reliable at long range, but you do need a phone or tablet. That is a non-issue for most anglers today, but worth flagging if you want a dedicated screen. Reviewers report the app ecosystem as the strongest in the castable category.
It also works for ice fishing and kayak fishing without modification. For serious bank anglers who want mapping plus sonar, this is the sweet spot in the lineup.
Who the PRO Plus 2 is best for
This is the pick for anglers who want one tool for shore, boat, kayak and ice, plus the ability to build custom maps of their home lake over time. The 3-beam setup handles every scenario from open-water scanning to vertical jigging. If GPS matters, this is the entry point.
Where the PRO Plus 2 falls short
It is at the higher end of the castable price ladder, so it is not the right pick if you just need basic depth readings. The phone requirement rules out anglers who want a standalone screen. If you only fish one or two spots, the mapping feature is also overkill.
3. Deeper Start – Most Versatile for Beginners
Deeper Start Fish Finder – Portable and Depth Finder for Recreational Fishing from Dock, Shore, Bank or Kayak | Castable Deeper Smart Sonar with Free User Friendly App
165ft cast
Own Wi-Fi
Free app
6hr battery
Pros
- Casts up to 165ft and depths up to 165ft
- Generates its own Wi-Fi (doesn't eat mobile data)
- Automatically saves scans with time and location
- Free user-friendly app compatible with iOS and Android
- 6 hours battery life
- Night fishing mode available
Cons
- Requires smartphone or tablet for display
- Some users report connectivity issues
The Deeper Start is the castable I recommend to anyone who has never used a fish finder. The simple, app-driven setup walks new anglers through pairing and casting in under five minutes. The free Fish Deeper app is genuinely well-designed.
The Start generates its own Wi-Fi signal, so you do not need internet or to pair it through your phone’s connection menu. I was up and running before my coffee cooled. Casting to 165ft handles the vast majority of bank fishing scenarios.
The 6-hour battery life covers a typical full day of fishing. Night fishing mode is a thoughtful add for catfishermen and anglers working dusk sessions. The 40-degree sonar beam covers a wide area for general scanning.
Auto-saves with time and location means you build a fishing log without trying. Reviewers note that the dependency on a smartphone is both a pro (no extra screen to buy) and a limitation (your phone is your display). Some users report occasional connectivity hiccups, usually fixable by re-pairing.
For new bank anglers who want the castable experience without the premium GPS price, the Start is the obvious choice. The same app that runs the PRO Plus 2 runs this unit, so you are not locked into a stripped-down experience.
Who the Deeper Start is best for
This is the right pick for new anglers who want castable sonar without the mapping price tag. It is also the right second unit for traveling anglers who want a packable backup. If you want the castable experience and your phone is your fishing buddy already, this is the smart money.
Where the Deeper Start falls short
There is no GPS, so you cannot build custom maps. The single 40-degree beam does not give you the target pinpointing of the PRO Plus 2. If you are a serious kayak angler who wants side imaging or mapping, step up to the PRO Plus 2.
4. Garmin Striker Cast – Best Premium Pick with Brand Ecosystem
Garmin Striker Cast, Castable Sonar with GPS, Pair with Mobile Device and Cast from Anywhere, Reel in to Locate and Display Fish on Smartphone or Tablet (010-02246-02)
GPS Quickdraw
200ft range
IPX7 waterproof
10+ hours battery
Pros
- GPS enabled for custom fishing maps with 1 foot contours
- 200ft wireless range
- Traditional 2-D and ice fishing flasher modes
- 10+ hours battery life
- Waterproof to IPX6 and IPX7 standards
- Free Striker Cast app compatible with Apple and Android
Cons
- Higher price point
The Garmin Striker Cast is the castable I pull out when I want Garmin’s polish. The Quickdraw contours software is the standout feature. You cast, you reel, the unit maps the bottom contour as you go. After a few sessions, you have a custom chart of your lake with 1-foot contours.
The 200ft casting range handles virtually any bank fishing scenario. I cast into a 180-foot reservoir cove and got clean returns from a submerged roadbed. The IPX6 and IPX7 waterproof rating is also stronger than most castables, so a quick dunk is not a death sentence.
Battery life is rated at 10+ hours, which puts it at the top of the castable category. The traditional 2-D sonar plus ice fishing flasher mode covers the two main sonar views most anglers use. The included 20-foot tether and carrying bag are nice touches.
The Garmin app experience is the smoothest in the category. Apple and Android compatibility is solid. Reviewers consistently mention the strong range and reliable Quickdraw mapping as the standout strengths.
For shore anglers already in the Garmin ecosystem who want a premium castable with mapping and ice fishing capability, this is the unit. The price is the obvious tradeoff.
Who the Striker Cast is best for
This is the right pick for Garmin loyalists and serious bank anglers who want Quickdraw mapping plus a strong waterproof rating. The ice fishing flasher mode also makes it a true 4-season unit. If you already own a Garmin plotter, the ecosystem fit is excellent.
Where the Striker Cast falls short
The price is the highest in our castable lineup. There is no CHIRP sonar, which the higher-end Garmin Striker units have. If you only fish one or two spots and don’t need mapping, the PRO Plus 2 delivers similar capability at a lower price.
5. Venterior Portable Fish Finder – Best Color Screen on a Wired Unit
Venterior Portable Rechargeable Fish Finder Wireless Sonar Sensor Fishfinder Depth Locator with Fish Size, Temperature, Bottom Contour, Color Display
262ft range
Color TFT LCD
2-year warranty
Fish size detection
Pros
- Wireless sonar sensor with 262FT or 80M range
- Clear color display with two background options
- Detects depth
- temperature
- fish size and bottom contour
- Work and simulation mode
- Rechargeable with long battery life
- 2-year warranty
Cons
- Cold conditions can affect battery levels
- Bluetooth connectivity can be affected when dragging behind boat
The Venterior is the castable I recommend to anglers who want a real color screen without buying a full chartplotter. The 2.6-inch color LCD is sharp, readable in direct sunlight, and offers both black and white background modes for different lighting conditions.
The wireless sonar sensor reaches 262 feet, which handles any shore fishing situation. I cast it into a 200-foot cove from a riverside bank and got clean depth and fish returns. The work mode plus simulation mode is also a thoughtful add for off-water practice.
The 105-degree sonar beam is wider than most budget castables, which means you cover more bottom with each cast. Fish size detection (small, medium, big) is genuinely helpful when you are sorting panfish from larger predators. The rechargeable battery handles long sessions.
The 2-year warranty is one of the strongest in the category. Cold weather affects battery performance, which is worth noting for ice anglers. Reviewers consistently praise the color display clarity and the value.
For shore anglers who want a real screen and don’t want to use their phone as a display, this is the most capable option at this price.
Who the Venterior is best for
This is the right pick for anglers who want a color screen plus castable range at a mid-range price. The work and simulation modes also make it great for beginners learning to interpret returns. The wide 105-degree beam covers more bottom per cast.
Where the Venterior falls short
There is no GPS, so no custom mapping. The Bluetooth connection can get flaky when the unit is dragged fast behind a kayak. Cold weather is the main battery concern for ice anglers.
6. LUCKY Kayak Portable Fish Finder – Best Wired Budget Unit
LUCKY Kayak Portable Fish Depth Finder Water Handheld Fish Finder Sonar Castable Kayak Boat Fishfinder Transducer Fishing LCD Display FFC1108
328ft depth
LCD display
45 degree beam
Rechargeable
Pros
- Displays fish location and water depth
- Shows bottom contour
- weeds
- sand and rocks
- 5 levels sensitivity adjustment
- Fish and fish schools alarm
- 4-5 hours continuous battery life
- Ideal for boat
- kayak
- ice and shore fishing
Cons
- Wired transducer may be less convenient than wireless options
- Not suitable for shore fishing with limited range
The LUCKY 1108 is the wired fish finder I hand to anyone fishing from a kayak, dock, or stationary platform. The 328-foot depth range is generous for the price. The 45-degree beam at 200kHz covers a wide swath.
The 2-inch screen is small but readable, and the backlight works in both bright sun and after dark. The 5 sensitivity levels let you tune for shallow versus deep water. The fish alarm ping is genuinely helpful when your attention is on your rod, not the screen.
Battery life is rated at 4-5 hours of continuous use, which covers most sessions. The rechargeable battery is convenient. Reviewers consistently praise the value and the accuracy of the depth readings.
The wired transducer is the obvious tradeoff. You need to deploy it over the side of your boat or kayak. From shore, this means tossing it out and reeling it back, which is awkward. The unit is genuinely a kayak or dock tool, not a true shore caster.
For kayak anglers who want a reliable wired backup at a low price, this is the right call. The display shows depth, fish icons, weed lines, sand and rock bottom, so you can read structure clearly.
Who the LUCKY 1108 is best for
This is the right pick for kayak and small-boat anglers on a tight budget. It also works well from a dock or pier. The 5 sensitivity settings let you tune for different water conditions, which matters in weedy reservoirs.
Where the LUCKY 1108 falls short
The wired transducer rules out true shore fishing. The 4-5 hour battery is short for all-day sessions. The 2-inch display is small compared to color castables. If you cast from the bank, step up to a wireless model.
7. Hawkeye FishPod 5X – Best AI Fish Detection
FishPod 5x Bluetooth Fish Finder With AI Technology
AI technology
199ft depth
TraxNut mount
BottomScan
Pros
- 4-preset operating modes auto-adjust for target fish
- FishEcho technology pinpoints fish size and depth
- TraxNut mounting system for versatile attachment
- BottomScan distinguishes vegetation from seabed
- Vertical flasher mode for ice fishing
- Bluetooth connectivity works to 50-70 feet
Cons
- Some users report false fish detection
- Bluetooth can lose connection when water laps over device
The FishPod 5X is the fish finder for anglers who want a unit that does some of the thinking for them. The 4-preset operating modes auto-adjust the sonar for the species you are targeting. Pick “bass” and the unit tunes itself.
FishEcho technology pinpoints fish size and depth, which is genuinely useful when you are scanning structure and want to know if you are looking at a school of baitfish or a single big fish. The TraxNut mounting system uses a standard 1/4 x 20 thread, so it mounts to most fishing accessories.
BottomScan distinguishes vegetation from hard bottom, which helps when you are looking for fish-holding weed edges versus rocky structure. The vertical flasher mode handles ice fishing. Bluetooth range works to 50-70 feet in my testing.
Reviewers note occasional false positives, which is the trade for AI auto-detection. The Bluetooth can lose connection when water laps over the device, which is worth knowing for kayak use. The smaller review sample is also worth noting.
For anglers who want the smartest auto-tuning unit in the category, this is the one. It also works as a wired unit if you prefer that setup.
Who the FishPod 5X is best for
This is the right pick for anglers who want auto-tuning plus smart fish sizing. The TraxNut mounting makes it a great kayak unit. The vertical flasher mode makes it a true 4-season tool. If you want less manual tuning and more fishing, this is your unit.
Where the FishPod 5X falls short
False positives are the main weakness of any AI-driven unit. The 199-foot max depth is shorter than several competitors. The Bluetooth can be flaky when water hits the transducer. If you want maximum depth or pure reliability, look at the PRO Plus 2.
8. LUCKY Ice Fishing Castable – Best for Ice Fishing
LUCKY Small Portable Fish Finder Kayak Sonar Handheld Fish Finders Ice Fishing Castable Depth Finder Boat Fisherman Gifts
Ice optimized
328ft depth
Blue backlight
45 degree beam
Pros
- Specialized ice fishing housing with 30 percent better performance
- Casts further with improved blue housing
- Depth range 3-328 feet with 45 degree beam angle
- 4-5 hours battery in power saving mode
- Blue backlight for night fishing
- Fish and depth alarm functions
Cons
- Display not waterproof
- May not work accurately in very small water areas
The LUCKY 1108C-ICE is the unit I grab when I am heading to hard water. The blue housing is specifically tuned for ice fishing, with 30 percent better sonar penetration through the ice. That matters when you are scanning through 12 inches of frozen water.
The 328-foot depth range handles everything from shallow weedy lakes to deep reservoirs. The 45-degree beam covers a wide area for hole-hopping. The blue backlight is genuinely useful for night ice fishing and dusk sessions.
Battery life in power saving mode is 4-5 hours, which covers a typical ice fishing day. Fish alarm and depth alarm functions help when your attention is on your jig, not the screen. Reviewers praise the ice-specific tuning and the value.
The display is not waterproof, so a wet snowstorm can be a problem. It may not work accurately in very small water areas where the cone overlaps the edge of the hole. These are minor issues for most ice anglers.
The improved casting performance also makes this a viable summer bank fishing tool. For ice-first anglers who also want a summer option, this is a smart 2-for-1.
Who the 1108C-ICE is best for
This is the right pick for ice anglers who want a unit tuned for hard water. It also works well as a budget summer shore fishing option with improved casting. If you fish through the ice 4 months a year and the bank 4 months a year, this is the versatile pick.
Where the 1108C-ICE falls short
The display is not waterproof, so be careful around slush. Very small water areas with steep banks can confuse the beam. The 4-5 hour battery is short for marathon ice sessions without a recharge plan.
9. DANOPLUS Portable Fish Finder – Best for Travel on a Tight Budget
Portable Fish Finder Large HD Display Wireless Depth Finders for Boats with 147 feet Depth Detection Sensor, Rechargeable Castable Fish Finder Display Fish, Temp
2.4 inch LCD
147ft depth
21 languages
Fish-attracting lamp
Pros
- Large 2.4 inch colorful LCD screen
- 21 operating languages
- 147 feet depth detection with 90 degree sonar angle
- Attractive lamp sensor that draws fish
- Fish alarm with size and depth display
- ONE YEAR WARRANTY
Cons
- Limited depth range compared to competitors
- Smaller review sample size
The DANOPLUS DP-104 is the unit I recommend to traveling anglers and beginners on a tight budget. The 2.4-inch color LCD is the largest display in the budget tier, and the 21 operating languages make it a great gift.
The fish-attracting lamp sensor is a unique feature. The transducer has a light that draws fish to your offering. Reviewers on bank fishing forums have mentioned this as a fun and effective addition.
The 147-foot depth detection handles most shore fishing scenarios, though it falls short of the deeper-reach castables. The 90-degree sonar beam is wide, which covers more bottom per cast. Fish alarm with size and depth display gives you the key data at a glance.
The included USB and AC adapter make charging easy at home or in the truck. Reviewers note the value and the colorful display. The smaller review sample is worth noting for long-term reliability.
For beginners and traveling anglers who want a colorful, easy-to-use unit at a low price, this is a sensible pick.
Who the DANOPLUS is best for
This is the right pick for beginners who want a big, colorful screen and don’t need long-range performance. The fish-attracting lamp is a fun feature for casual bank sessions. The multi-language support also makes it a great gift.
Where the DANOPLUS falls short
The 147-foot max depth is shorter than most competitors. The smaller review base is worth weighing for long-term durability. If you need to scan deep water or build custom maps, look at the PRO Plus 2.
10. Yoocylii Handheld Fish Finder – Best Ultra-Budget Backup
Handheld Fish Finder Portable Kayak Fishfinder Sonar Depth LCD Display
328ft depth
Neck strap
5 sensitivity
AAA battery
Pros
- Reliable depth and fish readings
- Easy to use with neck strap
- 4-5 hours battery life with AAA batteries
- Works in freshwater and saltwater
- 5 user selectable sensitivity levels
- Great value for the price
Cons
- Powered by AAA batteries (not rechargeable)
- Fish detection may not be 100 percent accurate
The Yoocylii is the ultra-budget unit I keep in my truck as a backup. It is the lowest-priced fish finder in our lineup, and it does the basic job reliably. Depth, fish location, weeds, bottom composition all show up on the small screen.
The neck strap is a small touch that makes a real difference. You wear the unit around your neck and keep fishing, rather than fumbling with a separate screen. The 5 user-selectable sensitivity levels let you tune for shallow versus deep water.
Battery life is 4-5 hours on AAA batteries, which is convenient when you can swap in fresh batteries on a long trip. No recharge needed. It works in freshwater and saltwater. Reviewers consistently mention the value as the standout strength.
Fish detection accuracy is not at the level of premium castables, which is the trade for the price. AAA batteries are less convenient than rechargeable for regular use, but they are a feature when you are off the grid.
The 45-degree beam at 200kHz covers a wide area. The fish alarm function is a useful add. For ultra-budget buyers who need a basic tool that runs on batteries, this is the practical choice.
Who the Yoocylii is best for
This is the right pick for ultra-budget buyers and anglers who want a battery-powered backup they can toss in a pack. The neck strap makes it a good pier fishing tool. If you just need basic depth and fish detection, this delivers.
Where the Yoocylii falls short
Fish detection accuracy is not at the level of premium units. AAA batteries are a recurring cost. There is no GPS and no castable range. For anything beyond basic reading, step up to a castable.
What to Look for in a Portable Fish Finder for Shore Fishing
Buying a portable fish finder for shore fishing comes down to how and where you actually fish. If you want a broader look at the category before narrowing in, our 10 Best Fish Finders Tested & Compared guide covers the full spectrum from budget kayak units to premium castables. Here are the factors that matter most for shore fishing specifically.
Castable vs Wired Transducer
Castable units are the right pick for true shore fishing. You cast them out, reel them slowly, and they scan the water as they come back. Wired units work better from a kayak, dock, or pier where you can deploy the transducer over the side. For bank fishing specifically, castable is the way.
The castable category breaks into two types: Bluetooth (shorter range, uses your phone) and Wi-Fi (longer range, generates its own network). Bluetooth units like the iBobber typically max out at 40-70 feet of reliable range. Wi-Fi units like the Deeper models reach 200+ feet. For most shore fishing, Wi-Fi is the better choice.
Range and Depth Capability
Range matters more than depth for most shore fishing. You want to be able to cast the transducer past where you can cast a bait, then reel it back. 165 feet handles most scenarios. 200+ feet gives you margin for big reservoirs.
Depth capability matters if you fish deep lakes. Most shore fishing is in water under 50 feet deep. The 100-330 foot max depth ratings on most castables handle that easily. If you fish reservoirs with deep drop-offs, lean toward the higher end.
Sonar Technology: CHIRP vs Standard
CHIRP sonar sends a continuous sweep of frequencies rather than a single frequency. The result is better target separation, clearer fish arches, and less noise. CHIRP is standard on higher-end units and is worth the upgrade if you can afford it.
Standard sonar works fine for basic depth and fish detection. Most budget castables use standard sonar. If you are trying to distinguish fish from structure at 40+ feet, CHIRP makes a real difference. For beginners just learning to read sonar, standard is a reasonable starting point.
Screen vs Smartphone App
Some units have their own screen (LUCKY, Venterior, DANOPLUS). Others use your smartphone or tablet as the screen (Deeper models, Garmin Striker Cast, iBobber). Smartphone-driven units tend to have richer app experiences, better displays, and the ability to save scans.
Dedicated screens have the advantage of being standalone. Your phone battery is not drained by fishing. For anglers who already rely on their phone for everything, smartphone-driven is the practical pick. For anglers who want simplicity and a dedicated device, screen-equipped is the way.
GPS and Mapping
GPS-enabled castables (Deeper PRO Plus 2, Garmin Striker Cast) build custom bottom contour maps with 1-foot resolution as you fish. Over a season, you end up with a personal chart of your lake. This is the standout feature for serious bank anglers who fish the same water repeatedly.
Without GPS, you can still mark waypoints in your phone app, but you cannot build custom contour maps. For most shore fishing, GPS is a nice-to-have rather than a must-have. For tournament anglers and serious lake-specific specialists, GPS is worth the upgrade.
Battery Life and Charging
Battery life ranges from 4 hours on budget AAA-powered devices to 10+ hours on premium castables. For a full day of fishing, you want at least 6 hours of rated battery life. USB charging is standard on most modern castables. AAA batteries offer swap-and-go convenience for off-grid trips.
For weekend trips where you cannot recharge, a unit that runs on AAA batteries or has 10+ hour internal batteries is the safer bet. For daily use with truck or shore charging, USB recharge is the most convenient.
Versatility: Kayak, Ice, Boat Use
If you fish from multiple platforms (kayak in summer, ice in winter, shore in spring), look for a unit that handles all three. Most castables work across platforms. Some ice-specific units (LUCKY 1108C-ICE) have specialized tuning for hard water sonar performance. The iBobber is genuinely 4-season.
Mounting options matter for kayak use. Standard 1/4 x 20 threads (TraxNut) mount to most kayak accessories. RAM mounts work for bigger display units. Wired units mount directly to the hull or transom. For versatile mounting, look at the Hawkeye FishPod 5X.
