Bracket Installation
You can install the sonar unit on the top of a dash or from an overhead with
the supplied bracket. It can also be installed in the dash with an optional
IDA-3 mounting kit. If you use the supplied bracket, you may be interested
in the optional GBSA-1 swivel bracket kit. This converts the unit's gimbal
bracket to a swivel mount which can be used on the dash or overhead
mounting positions. Installation instructions for the in-dash and swivel
mounting kits are supplied with the adapter kits.
Mount the unit in any convenient location, provided there is clearance
when it’s tilted for the best viewing angle. Holes in the bracket’s base allow
wood screw or through bolt mounting. It may be necessary to place a piece
of plywood on the back side of thin panels to reinforce the panel. Make
certain there is enough room behind the unit to attach the power and
transducer cables.
Drill a hole in the dash for the power and transducer cables. The best
location for this hole is immediately under the gimbal bracket. This way,
the bracket covers the hole. The smallest hole the power and transducer
cable connectors can pass through is 5/8". After drilling the hole, pass the
transducer connector up through the hole from under the dash. Pass the
power cable down though the hole from the top. Slide the bracket over the
hole, then route the cables out the slot in the back of the bracket. Finally,
fasten the bracket to the dash.
Attach the unit to the gimbal bracket using the supplied gimbal knobs and
washers as shown above.
