Thank You
Thank you for purchasing a Piranha fishfinder from
Humminbird, America’s #1 Manufacturer of quality con-
sumer marine electronics
WARNING! This device should not be used as a
navigational aid to prevent collision, grounding, boat
damage, or personal injury. When the boat is moving,
water depth may change too quickly to allow time for you
to react. Always operate the boat at very slow speeds if
you suspect shallow water or submerged objects.
Installation Overview
Use the included installation guide to properly install your new Piranha. Installation
must be done correctly to ensure best performance.
Using the Piranha
The Piranha is the easiest to use fishfinder ever. For most anglers, all you’ll ever
need to do is Power On & Fish! The Piranha automatically determines depth and
makes adjustments to keep the bottom and fish visible on the display.
The Piranha uses sonar technology to send sound waves from the transducer into
the water. The returned “echoes” are plotted on the Piranha’s LCD display and cre-
ate a very accurate picture of the underwater world with distance to underwater
objects such as the bottom, fish and structure.
Powering ON and OFF
Press and release POWER-MENU to power the Piranha on. Press
and hold POWER-MENU until the unit shuts down to power off.
When Piranha powers on, the Start Up menu temporarily
appears. From this menu, select either Start-Up for on-the-water
use, or Simulator for learning to use
the system with simulated sonar data.
The Start-Up menu disappears after
several seconds and the Piranha
begins operation.
What You See On Screen
The Piranha displays underwater information in an easy-to-
understand format. The top of the display corresponds to the
water surface, and the bottom of the display corresponds to the
Depth Range automatically selected for the current water depth.
The Bottom Contour varies between the two as the depth under
the boat changes. Digital readouts provide precise information
for depth, fish and water temperature
(separate purchase required).
