Review on Portable WiFi Fish Finder with GPS for Kayaks, Boats, and Ice Fishing - Deeper PRO+ Smart Sonar for Deeper Insights by Amphai Sangchang ᠌

In general, the impressions are very pleasant. I hope that the described shortcomings will be just speculation. Just bought a cover for winter fishing. The feeling that the price for it is too high (2.5k), yet there is nothing but a primitive box and insulating plates. But I bought it - and I bought it, it might come in handy. Some pros: The sounder is compact. The cover under it is comfortable and with a carabiner, which is important for winter fishing. The application on a mobile device is innovative. No need to ate the firmware - there is an application. That is, by buying a product, you can get new chips in the future at the expense of the mobile application. I went fishing to test (payer, a lot of fish, depth up to 5 meters) - it shows everything. Interesting to watch, great to watch. Cons below: The following did not live up to expectations: After the purchase, I read that the battery built into the deeper holds only 300 charge-discharge cycles. Taking into account the rather fast discharge, this can conditionally be equated to 300 fishing trips with an echo sounder. For 20k to buy an echo sounder for 300 fishing trips is strange. I sincerely hope that 300 is the minimum amount that the manufacturer guarantees, and if the device is used correctly, it will last several times longer. The manual also indicates the possibility of replacing a used battery at your own expense using the outofwarranty deeper service - but I did not find this service and its contacts in 2022 (maybe I was looking badly?) The rubber gasket, which should maintain complete tightness, seems reliable, but I still worry a little about it. It is indicated that the echo sounder cannot be used at extremely low temperatures - it is dangerous. But still, the declared range is -20 +50 - which is acceptable, I would like it to be up to -30 degrees - we'll see.
