What You See On The Display - Humminbird PiranhaMAX 155 Installation And Operation Manual

What You See On the Display

The PiranhaMAX displays underwater information in an easy-to-understand
format. The top of the display corresponds to the water surface at the
transducer, and the bottom of the display corresponds to the Depth Range
automatically selected for the current water depth. The Bottom Contour varies
as the depth under the boat changes. Digital readouts provide precise
information for depth, fish, and water temperature.
As the boat moves, terrain and bottom composition variations are displayed.
Fish, baitfish, and thermoclines (underwater temperature changes) are
displayed when detected. Underwater conditions vary greatly, so some
experience and interpretation is needed to realize all the benefits of the
PiranhaMAX – use the following illustration as a guide to the most common
conditions and practice using your PiranhaMAX over known bottom types.
