See what's under the surface before you cast.
This castable sonar unit sends live readings straight to your phone or tablet. The compact transducer (about 60 x 68 x 63 mm) links over a 2.4 GHz wireless connection to iOS or Android. It reaches down to 48 m / 160 ft with a 90 degree beam at 125 kHz, so you can spot fish, depth, and the basic shape of the bottom.
A built-in 3.7 V, 1000 mAh rechargeable battery runs up to 20 hours per charge. Pair it over Bluetooth, open a compatible app, and watch fish icons, rough size, water depth, and temperature where the app supports it.
