Review on Portable WiFi Fish Finder with GPS for Kayaks, Boats, and Ice Fishing - Deeper PRO+ Smart Sonar for Deeper Insights by Deva Raja (kamal) ᠌

Different pros: pluses: light weight, a huge number of settings for all types of fishing, working with maps and creating maps of reservoirs, an angler's calendar that has never failed. I got a New Year's set with different goodies in the kit (a cover for night fishing, a smartphone holder and a multi-tool). You only need to buy a winter cover for your smartphone. Some cons: confuse the screws in the cover for attaching the echo sounder to the rod. It seems that with inept casting they can unscrew. Treated with threadlocker. a small drop before twisting and you can not be afraid that the echo sounder will fly away. Didn't find any other flaws.
