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

I had Deeper Pro for 6 weeks, used it 8 times in that time, after that it stopped working. I can still charge it and drop it in water, the phone will connect and give me the correct battery and water temperature readings on contact. It shows a generic "too shallow or too deep" error message and doesn't display any sonar data. I've tested it in places I knew was 20 feet deep and places it's worked before. Called the US support number, asked me 3 basic questions (Have you updated the app, is the screw in the right place to plug it in, the app says it's plugged in) and then was told that I someone would send an email (do not call me) by the next business day. just wow. I would return this to Revain except it has been 7 days since I returned it.
