- PiranhaMAX 4 – Dual Beam sonar (200/455 kHz) for solid depth, fish arches and structure reading. Ideal as a straightforward depth sounder.
- PiranhaMAX 4 DI – Dual Beam plus Down Imaging for a clearer, more detailed view of timber, rocks, weed and fish directly under the boat.
- Portable (PT) options – Same performance in a portable kit with case and suction-cup transducer, perfect for kayaks, hire boats or moving between vessels.
All models include Fish ID+, depth and fish alarms, zoom, tilt-and-swivel mount and a transom transducer (or portable kit). No GPS or networking — just dependable sonar that gets you on the water quickly.
Select your sonar package above to build the PiranhaMAX setup that matches your fishing style.
