Humminbird PiranhaMAX 160 PT Portable Fishfinder Review

The 4-inch Humminbird PiranhaMAX 160 portable fishfinder with dual beam sonar can be attached to your boat, kayak, pontoon boat or whatever you like to fish from with a reliable strong suction cup mount that can be easily adjusted. It also comes with D-rings to strap down the unit if necessary.  The 12-volt gel battery is rechargeable and is impressively long-lasting. One user said he took it out fishing for four hours, left it uncharged until the next fishing trip and used it for another four hours without it needing to be recharged. Batteries seem to be the biggest drawback with portable electronics as far as usage time between charges, so this is a big plus with the PiranhaMAX 160, especially for multi-day fishing trips when recharging may not be an option. This fish finder comes with a storage case that everything fits into for easy transport.

One drawback that someone noted is that the on/off button can be easily pushed by mistake, which could mean arriving to your fishing location with a drained battery. They recommended that you disconnect the battery from the unit while not in use or at least check it before you put it away. One other person recommended keeping the transducer wire short if you are mounting on a boat with a motor so if the suction cup comes loose, the wire will not get wrapped up in the prop.

Simplicity and Performance

Four-Inch Grayscale Display

The PiranhaMAX 160 PT features a four-inch, four-level grayscale display with 160 x 128 pixel resolution, so you get a good view of the action--even in direct sunlight.

Simple Fishfinding

The PiranhaMAX extremely easy to use. For most anglers, all you'll ever need to do is power on and fish. The PiranhaMAX automatically determines depth and makes adjustments to keep the bottom and fish visible on the display.

PiranhaMAX 160 PT Screen PiranhaMAX 160 PT Transducer

The PiranhaMAX uses sonar technology to send sound waves from the transducer into the water. The returned "echoes" are plotted on the display, creating a very accurate picture of the underwater world, including distance to underwater objects such as the bottom, fish, and structure.

Dual Beam Sonar

The PiranhaMAX 160 PT uses a 200/83 kHz dual beam sonar system with a wide (60 degree) area of coverage. Dual Beam sonar is optimized to show the greatest bottom definition using a narrow (20 degree) beam yet can still indicate fish found in the wide (60 degree) beam when the Fish ID+ feature is turned on. Dual Beam is ideal for a wide range of conditions--from shallow to very deep water, in both fresh and salt water. Note that boat speed, wave action, bottom hardness, water conditions, and transducer installation can all affect depth capability.

Fish ID+

Fish ID+ uses advanced sonar processing to interpret sonar returns, and displays a Fish Symbol when very selective requirements are met. When a fish is detected, a fish icon and its depth are displayed above the return that has been classified as being a fish. Three different fish icons represent intensity of the sonar return, and provide an indicator of relative fish size.

Fish and Depth Alarms

When Fish ID+ is on, you can set an alarm to sound when the PiranhaMAX detects fish that correspond to your settings. You can also set a depth alarm from 3 to 99 feet--an audible alarm sounds when the depth is equal to or less than the setting.


The PT version of the PiranhaMAX 160 comes with a soft-shell carrying case, suction cup transducer, integral cable storage and a 7Ah battery and charger so you won't miss a fish, no matter how far away from home you are.
