Deeper smart sonars have been designed to be as simple and quick to use as possible. Just attach the device to a fishing-line and put it in the water; this will switch the device on. Then cast it to the spot you want to scan, and your Deeper does the rest. It will automatically transmit detailed data of the depth, temperature, vegetation and structure of the water. And best of all, it will show you where the fish are hiding. The Deeper app has modes suitable for shore, boat and ice fishing; just chose the mode that’s best for you and get fishing.
