X37TX and X47TX quick release mounting bracket. Slots in the base
allow routing the cable from beneath the mount. Shown on swivel base.
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.
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.
