Can Deeper Smart Sonars work underwater?

Deeper smart sonars are designed to float on the surface of the water, and we don’t recommend submerging the device (it is waterproof up to 1 meter). Of course, it may get submerged briefly if the water is rough, and this shouldn’t affect the performance of the device. It records information for 5 seconds while underwater. After resurfacing, it transfers that data back to your phone.
