Review on Deeper PRO Smart Sonar - Portable WiFi Fish Finder for Kayaks, Boats, and Ice Fishing on Shore by Jonathan Sanders

Used for ice fishing, works great! Can't wait to try this in open water soon. Get some kind of charger for your phone! UPDATE: Works great all year round. Definitely good below -4°F. No interference with Vexilars, even from 2 feet away. I also found it useful to carry a portable battery to charge my phone and ball. I use it in the summer when I tow it behind an RC boat. I can find the exact spot on the crib/descend/weed edge and drop my bobber right on the spot. It's hard to tell from the photo, but there are 2 straws to keep the musky line from getting tangled in the support.
