    Should add feedback after going to the big water! Inside everything is very worthy! On the fasteners there are separate rubber plugs, and another rubber ring is installed, which confirms that the ingress of moisture into the device is almost impossible, unless pour water into the charging connector. The battery I think will be enough for a while. I’ll go out to the big water and add photos. Disassembled and posted photos of the insides, so that others did not look for shortcomings in the Assembly. Everything looks very good.

    Delivery to Karelia 25 days, for some reason through Finland. I tried the echo sounder on the lake. depth shows true. the water temperature in 5-10 minutes also shows true. since the temperature sensor is inside, you will have to wait until the body cool. the presence of fish in the pond I hope shows true, several times showed the presence. I tried to experiment with the luster lowered into the hole, reacts if the luster moves. fishing has not yet been possible, waiting for the weekend.
