The Deeper MAX is a castable sonar ball that pairs with your phone over Wi-Fi, so you can scan bottom depth, contours and fish from shore, a kayak, a boat or through ice. Its CHIRP sonar and improved GPS (rated to about 400 ft of casting range) separate it from the older PRO line, and the free Fish Deeper app adds personal 3D depth maps and unlimited cloud storage. It scans to roughly 330 ft and runs about 15 hours per charge. It suits anglers who want a portable, no-wiring fish finder and map builder; dedicated boat units still offer bigger screens and live sonar, but they cost more and need installation.

Owners generally rate the MAX as a solid step up from the PRO for GPS accuracy and mapping, and like the simple cast-and-scan workflow. Complaints center on the phone-tethered experience and connection dropouts at range.
