Portable Sonar Installation

slack for tilting and turning the unit and attaching the connector. (The snug fit of the push-on waterproof connector requires some force to attach.)

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

Attach the unit to the bracket by first connecting the power/transducer cable. Then, hold the sonar unit vertically and slide it onto the bracket from above. (The back of the unit should be touching the front of the bracket as you lower it into position.) As you push down, the unit will lock into place with a distinct click.

Depress ratchets to release

Swivel base

Adjust viewing angle: use one hand to press and release the spring-

loaded ratchets while you move the unit with the other hand.

To adjust the vertical viewing angle, pinch the ratchets with one hand, then tilt the unit with your other hand. Release the ratchets and the unit locks into the new position. You can also turn the unit on its special swivel base for a better horizontal viewing angle. To dismount the unit for storage, press the ratchets and lift the unit off the bracket.

Like many Lowrance products, these sonar units are capable of portable operation. The X51 Pro uses the optional PPP-12 portable power pack. The PPP-12 package includes the power pack, battery adapter and a portable transducer. Batteries are not included. Each power pack has a storage compartment for the portable transducer. The PPP-12 can be used with eight AA alkaline batteries. To use a portable power pack, you simply install the batteries and then attach the sonar unit to the power pack's bracket.
