Lowrance Eagle 4x Fishfinder vs Deeper Pro+ 2 Fish Finder

Buy the Lowrance Eagle-4x if you want a fixed, always-on sonar on the boat with its own screen, a transom transducer and no phone in the loop. Buy the Deeper Pro+ 2 if you fish from shore, a kayak or a paddleboard and want to cast a wireless sonar to reach water you cannot cover, plus GPS mapping. The Eagle-4x is a conventional sounder with a 4-inch IPS display and autotuning sonar; the Deeper is a castable Wi-Fi unit that runs on your phone and adds CHIRP, GPS and lake mapping. Owners rate the Eagle-4x around 4.1 out of 5; the Deeper's narrow 7-degree beam gives sharper target separation but a much tighter view of the water column.

• Choose the Lowrance Eagle-4x if you want a dedicated screen on the boat, a transom-mounted transducer and simple key controls with nothing to charge or pair.
• Choose the Deeper Pro+ 2 if you fish from shore, kayak or SUP and need to cast to reach deeper water, with GPS mapping and phone-based CHIRP sonar.
