Remove any smears with a gentle wipe of a microfiber cloth.


Can the units change to metric?

Customers can change from feet to meters and Fahrenheit to Celsius displays.

Can the transducer be removed?

It is not easy to remove the transducer after each outing. The cable is hardwired to the transducer so the cable would need to be removed at the same time.

Memory cards can be moved from one device to another as long as they accept the cards. Waypoints etc can be saved on the memory card.

Can the transducer cable be installed through the hull?
