PiranhaMax 4PT 4.3" Display

The Humminbird PiranhaMax 4PT is a portable fishfinder built for anglers who need a compact sonar unit with a dedicated transducer. It suits small-boat, kayak or occasional users wanting a self-contained kit for locating fish and bottom structure. It is not for mariners requiring integrated chartplotting, networking or larger screen real estate.

Dual Beam Sonar 600 ft Depth

Dual Beam sonar delivers 2400 Watts PTP output with coverage angles of 16° and 28° at -10 dB, reaching a maximum depth of 600 ft. The narrower 16° beam provides detail for target separation while the wider 28° beam scans a broader area. Very deep offshore waters beyond 600 ft exceed the unit's sounding capability.

XPT 9 28 T Transducer Portable Case

The included XPT 9 28 T transducer enables the Dual Beam operation straight from the box. A soft-sided carrying case protects the 4.3" colour TFT display and electronics during transport. The tilt and swivel mount allows flexible viewing angle adjustment on the water.

Questions about this item

Will the XPT 9 28 T transducer fit the transom mount on my older jon boat?

The XPT 9 28 T transducer included with the PiranhaMax 4PT uses a standard transom bracket that fits most flat-stern small craft.

How can I confirm the dual-beam sonar is pinging correctly on the 4.3" color TFT display?

Power the unit and watch the screen; you should see two distinct cones — one at 16° and one at 28° — scrolling with bottom returns down to 600 ft.

Does the box contain the tilt-and-swivel mount and portable case, or must I buy them separately?

Both the tilt-and-swivel mount and the soft-sided portable case are packed in the box with the display and transducer.
