The Best Castable Fish Finders: 2024 Top Picks and Pro Guide

The Lowrance FishHunter PRO has some pretty awesome features for shore fishermen. This fish finder links directly to your phone, but it doesn’t require a data connection.

Instead, the FishHunter Pro creates its wifi signal that you connect to using the Mobile app for your phone.

The fish finder also includes a traditional sonar view and a fish mode which shows fish icons on the sonar display, so you can pick whatever mode you prefer.

The coolest feature of this fish finder is the mapping feature. This feature allows you to create custom color contour charts of your favorite spots, revealing depths of every area you can reach by casting, allowing you to save those maps to use whenever needed.

The unit also runs three frequencies for sonar at  381kHz, 475kHz, and 675kHz.

Pros:

• Contour mapping
• Wifi signal
• Multiple frequencies

Cons:

• Shorter casting range
• Large unit

The Deeper Start Smart fish finder is incredibly portable and easy to cast. It, like the Lowrance and others, creates its own wifi signal allowing you to use the fish finder and app without draining the data on your phone.

You can cast the fish finder up to 165 feet away from you and still have enough signal to see the readings on the app. The sonar is also powerful enough to accurately ping to depths of 165 feet with a 40-degree sonar cone.

The fish finder also comes with an automatic night fishing mode and 6 hours of battery life while only taking 2.5 hours to charge. The deeper is compatible with both Android and IOS platforms.

Pros:

• Long battery life
• Very portable

Cons:

• Short casting distance
• Wide sonar cone

The iBobber is a very easy-casting and aerodynamic sonar unit that you can connect to using your phone via Bluetooth.

The iBobber has 2 line tie points, along with an LED beacon to help with night fishing.

On top of that, you get a whopping 10 hours of battery life and a sonar maximum depth of 135 feet. Works on both Android and IOS with a completely free app.

Pros:

• 2 line points
• Long battery life

Cons:

• No mapping feature
• Short distance reading

The Deeper Chirp is the high-end model of the Deeper series of castable fish finders.

Like the other fish finder, the Chirp also has its own wifi signal, but things get drastically better with this model compared to the Start Smart by deeper for an added price.

The Chirp can cast out to 330 feet and maintain solid connectivity with your smart device, allowing you to really reach out with maximum casting distance to discover what’s really out there from shore.

This means it also has a sonar depth of that same 330 feet of depth, which should be more than any shore angler could ever ask for.

With such huge depth reading capabilities, it can also read accurately in as little as 6 inches of water, with a 4-inch precision readout of anything it pings.

It can also be used to make contour or bathymetric map readouts that you can save and use anytime you return to the area on your smart device.

The Chirp also has fast charging reaching 100% in 75 minutes. This is a great option for any shore fisherman or kayak angler.

Pros:

• Precision sonar
• Long distance casting
• Mapping

Cons:

• The price is higher than others on the list

The Lucky fish finder comes with its own handheld device that features a 2.5-inch LCD screen. Allowing you to use it without the need for a smart device or wifi, while it stays around your neck via the provided lanyard.

The range of the transducer from your handheld device is 196 feet with 147 feet of depth for sonar, which should be plenty for most anglers using these types of fish finders.

The sonar also has multiple setting options such as detection sensitivity, zoom, depth alarm, and fish alarm.

The Lucky also has a very long battery life, with 4 hours on the handheld LCD device, and 10 hours for the sonar unit itself.

Pros:

• No smart device needed
• Multiple settings

Cons:

• Small screen
• Short range

Our last Deeper model on the list is the PRO. It’s an in-between of the Start and the Chirp.

With a total cast distance connectivity of 330 feet like the Chirp, but with only 260 feet of depth readings, which still should be more than enough for almost all anglers.

It also features dual beam sonar frequency with a 55-degree wide beam and a 15-degree narrow beam.

Everything else is pretty much the same as the other models. And like the Chirp, you can still create bathymetric maps of all your favorite fishing spots.

Compared to the other two Deeper models listed, the main point of this is price, which is in between the others and comes with additional features over the Start.

Pros:

• Long range
• Wide and narrow beam settings
• Mapping

Cons:

• Less depth than the chirp model

Here’s another offering from Lowrance that you can use on your smart device by making its own wifi connection.

This unit comes with a directional casting mode for open-water fishing or an ice fishing mode if you’re out on the ice.

Along with those 2 modes, it also comes with 3 different frequencies for the sonar, these frequencies are  381kHz, 475kHz, and 675kHz.

The Lowrance app allows you to log catches, follow friends, or even stream your sonar display live anywhere in the world.

And like some of the other offerings on this list, you can map out all your favorite spots with the contour mapping feature.

Pros:

• Open water and ice fishing modes
• Multiple frequencies
• Mapping

Cons:

• Short range of 150 feet casting distance
