• If your boat remains out of the water for a long period of time, it may
take some time to wet the transducer when it is returned to the water.
Small air bubbles can climb to the surface of the transducer and
interfere with proper operation. These bubbles dissipate with time, or
you can wipe the face of the transducer with your fingers after the
transducer is in the water.
PiranhaMAX Portable Case Maintenance
If the portable case comes into contact with salt spray, wipe the
affected surfaces with a lint-free cloth, then apply a commercially
available anti-corrosive treatment to all exposed electrical contacts.
If the portable case bag becomes dirty, clean the bag with mild soap,
water, and a soft rag or brush and then hang it up to dry.
How to Remove Water from the Portable Case
Open the front zipper and pull the case down to allow water to exit the case.
If needed, remove the case from the plastic base and air-dry it. Follow
recommended maintenance procedures for salt spray exposure if needed.
