3.There is no bottom readingvisible on the display.
If the loss of bottom information occurs only at high boat speeds, the transducer needs adjusting – see your PiranhaMAX™ Installation Guide for details. Also, in very deep water, it may be necessary to increase the sensitivity setting manually to maintain a graphic depiction of the bottom. If you are using a transducer switch to connect two transducers to the PiranhaMAX™,make sure that the switch is in the correctposition to connect a transducer that is in the water. (If a trolling motor transduceris selectedand the trolling motor is out of the water,no sonar informationappears.) If none of these actions solves the problem, inspect the transducercablefromend to end for breaks, kinks, or cuts in the outer casing of the cable. If the transducer is connectedto theunit through a switch,temporarilyconnect it directlyto theunit and try again. If none of these actions identifies an obvious problem, the transducer itself may be at fault. Be sure to includethe transducer if returning the unit for repair.
4.When in very shallow water, I get gaps in the bottom reading and inconsistentdigital depth indication.
The PiranhaMAX™ will work reliably in water 3 feet (90 cm) or deeper. Remember that the depth is measured from the transducer, not from the surface of the water.
5.The unit comes on before I press the
Check the transducer cable — if the outer jacket of the cable has been cut and the cableis in contact with bare metal, you will need to repair the cut with electricaltape. If thereis no problem with the cable,disconnect the transducer from the unit and see if the problem is corrected,to confirmthe sourceof the problem.
6.I get gaps in the reading at high speeds.
Your transducer needs adjusting. If the transducer is
