The Deeper START Smart Fish Finder is an entry-level castable sonar for shore anglers. This review is based on Deeper's specs and owner reviews; we have not tested it ourselves. This compact device weighs just 0.08 kg, generates its own Wi-Fi signal, and scans depths up to 165 feet with a 40° beam angle.

Connectivity complaints are common in owner reviews, and the battery life could be longer, but it is good value for recreational fishing. Here is a closer look.
