The iBobber Bluetooth Smart Fish Finder can make accurate sonar scans 100 feet out and 135 feet deep. Choose from a raw sonar structure contour view or the fish-tagging view that color codes by fish size. 

They claim to be the smallest finder on the market. It doubles as a regular fishing bobber when you’re not using it for sonar readings. You can also fish for 10 hours or more on a single charge.

The iBobber syncs with an app and also works with smart watches. 

The app has an interactive map that allows you to tag spots and log your trip with information about when you were there, temperature, lure type, fish quantity, and fish type. It also includes a lunar calendar and weather information.

The Garmin Striker Cast has a traditional 2-D mode and an ice-fishing flasher mode. It’s easy to cast with a 20-pound+ weight fishing line. It works in freshwater, and below the ice to show structures and fish in the water around you.

You can use your mobile device to stream data from the Garmin up to 200 feet away. The finder works with the STRIKER Cast app on smart devices to stream live sonar information and locate fish. The Garmin Quickdraw Community has downloadable maps with up to 1-foot contours. 

The USB-rechargeable battery lasts 10+ hours on a charge, and powers off automatically when you remove it from the water.

A version with GPS and ones that include a bonus fish scale or cell mount for your fishing rod also exist.

Deeper Start Smart Fish Finder

The castable Deeper Start Smart Fish Finder only weighs 2.3 oz (65g) and is 2.3 inches (60 mm) high, so the small size makes it easy and comfortable to cast. It has a 40° sonar scanning beam that can scan 165 ft (50 m) wide and deep. 

The fish finder transmits data to the Deeper app on your mobile smart device concerning fish location, size, water depth, and contours of underwater structures and vegetation. Each scan automatically saves to the app with time and location stamps. It also comes with a user-friendly instruction manual.

This fish finder includes an automatic night fishing mode. The battery only lasts 6 hours and has a 2.5-hour recharge time.
