Pro when mounted on quick release bracket.

If you wish, you can fill in the hole around the cable with a good marine sealant compound. (Some marine dealers stock cable hole covers to con- ceal the opening.)

This unit uses a quick release mounting bracket. When you run the cable through the hole, make sure you allow enough slack for tilting the unit and attaching the connector. (The snug fit of the push-on water- proof connector requires some force to attach.) Also be sure there is enough cable slack for rotation if you decide to use the optional GBSA-3 swivel base. The swivel base lets you to rotate the sonar so it can be seen from different parts of the boat.

Align the bracket over the cable hole with the cable slots facing away from you and fit the cable through one of the slots. Fasten the bracket to the dash using the three screw holes.
