Bank fishermen can use the Garmin for shore fishing, river fishing, kayak fishing, and even as an ice fishing fish finder as it has an ice fishing flasher mode. It would even be awesome on a small boat fishing trip too!

This castable fish finder connects to your android or ios device, phone or tablet, via its own WiFi hotspot. Once connected, you simply download the free striker cast app, attach the small floating transducer to your fishing line on a separate stiff rod, cast it out into the water, and you’ll start seeing accurate sonar images or your phone/tablet using the dual-beam sonar.

The castable sonar unit has a 200 ft connection range so you can see what’s sitting way off the shore and with a maximum scanning depth of 150 feet, nothing is going to get missed.

The Deeper Smart Sonar Deeper CHIRP fish finder could be the best portable fish finder around as on paper, it really can do it all. Whether you want to use it for shore fishing, from a small boat, or ice fishing, it can technically do the job and a lot more. Because of its portability, this is also a great kayak fish finder.

What makes this castable deeper fish finder so appealing is that it comes with Chirp sonar and it’s the one castable fish finder in the world that does. CHIRP uses multiple sonar frequencies simultaneously to give you the most accurate readings possible of the entire water column, helping you see and hopefully catch more fish.

Not only does it use CHIRP but it also uses 3 scanning beams, more than most fish finders, which gives you amazing detail of the bottom structure and any fish holding by it.

This sonar unit also comes with a flasher for ice fishing, GPS for marking spots, and will build contour maps of the areas you’re bank fishing from. You can even record sonar data to review at a later date.

With a castable range of 330 ft and a maximum scanning depth of 330 ft, you can really see what is lurking under the surface while bank or shore fishing.

Its battery life isn’t so great at 6 hours as you’ll have to recharge during a day of fishing. Luckily it recharges first but opening the charging port can be a bit tricky.

Overall this portable fish finder is great for shore fishing but it does have some glitches. Some people love it but some have problems with the connection.

Cons

  • Limited castable range

The Vexilar SP200 T-Box Smartphone Fish Finder is a portable fish finder for kayaks and boats, but it could be used as a castable fish finder by attaching it to a float. I’ve included it because it is extremely reliable, accurate, and castable if you want it to be.

The main issue with this unit is that it needs to be connected to a power source and has a 25 ft cable, so despite being able to connect to your phone from 300ft away, its castable range is limited.

But, if you are pulling this unit behind a kayak or jon boats then you are in business. It creates a stable connection with your phone/tablet that never drops, it merges with Navionics so get GPS, charts, and a fish finder all on one screen.

The sonar data on these is super accurate, it works at speeds under 10 knots, and it gives accurate readings down to 240 feet. You can use it with a traditional view or with fish symbols and it has fish, shallow water, and low battery alarms too.

Overall this is one of the most comprehensive and affordable portable fish finders around and the only negative is the castable range.

Cons

  • Connecting to the unit isn’t always easy

If you’re shopping on a budget then the ReelSonar iBobber Castable fish finders might be just what you’re looking for. While these fish finders are very affordable at under $100, they do enough for anyone wanting to fish from the beach or a lake/river bank.

The fish finders work just like the others, by creating a WiFI hotspot that connects to the iBobber app on your phone/tablet. It maintains a solid connection and has a castable range of up to 100 ft, which is pretty good.

The sonar isn’t very high-tech as it runs just a single beam and frequency but still scans accurately down to 135 ft. You’ll be able to see fish, fish hold structure, depth changes, and even bottom types. The fish will be displayed with depth marks and it separates them into two sizes – bigger or smaller than 15 inches. The fish are even tagged with depth markers so you can fish with pinpoint depth accuracy.

You can use this unit as a bobber, it has an LED light for night use, it self-maps the water bed for you, and the GPS lets you mark spots. The app also comes with a trip log feature, provides you with weather reports, and has alarms for fish and shallow water.

Overall, these fish finders are pretty amazing for their price tag and the only thing to be wary of is that it can be hard to connect to the device, but it usually does connect in the end.

Things To Consider When Buying A Castable Fish Finder

Things To Consider When Buying A Castable Fish Finder

Connection Quality & Range

Connection quality & range are two of the most important parts of a castable fish finder. Since the unit connects to your phone, if the connection breaks, the fish finder is useless. If the connection range isn’t very good, then you’ll be limited as to how far from the bank you can look for fishy areas.

Make sure the unit you get has good connection stats and that you can cast it as far as you need to.

Battery

If the battery dies while you’re fishing, the fish finder is also rendered useless and you will have to stop fishing to recharge it. Make sure the unit your go for has a battery that lasts at least 6 hours or more – 10 hours is best.

Sonar, GPS & Mapping

Sonar, GPS & Mapping are the three main features you want your unit to be able to do, and all the fish finders featured above have them. If you can see good sonar images, use GPS to mark spots, and the unit builds maps for you, you have all the data you need to start catching more fish than ever.

FAQs

Can you use a fish finder on the bank or on shore?

Yes, you can use a fish finder on the bank or on shore as these fish finders use a wireless connection that pairs with your phone. This means you can cast out the fish finder unit from the bank or shore and then slowly wind it in. As you wind the unit in, you’ll start seeing accurate sonar images including depth, bottom structure, fish, fish size, and fish depth.

Which Fish Finder Should I Get

Which Fish Finder Should I Get?

Thanks for reading my article, I hope you enjoyed it and have found the right bank fishing fish finder for you. If you haven’t, here at the ones I’d go for and for different reasons.

The Garmin Striker Castable Sonar with GPS is the unit I would buy. It’s one of the best garmin fish finders and the most reliable unit featured with some of the best features at the same time. You can rest assured knowing it will connect, the battery will last all day, the sonar is accurate, it builds maps, has GPS, and it has a flasher for ice fishing.

The Deeper CHIRP unit would be my second choice as it does all the same things the Garmin Unit does plus more, but it’s not quite as reliable. By having CHIRP it will provide the best sonar images of all the units and it also reads deeper than all the others with a max of 330 ft. But, the connection can drop and you’re going to have to pause to charge it if you’re fishing all day.

For those of you on a tight budget, the iBobber is the one for you. As it is one of the best fish finders on the market today. Yes its connection range and max depth readings are almost half of the others but it does the important things – showing you fishing, building your maps, and more
