Transducer Installation Guide

Gimbal Mount Unit
The unit can be installed on the top of a dash or from an overhead. Mount the unit in any convenient location, provided there is clearance, when it is 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/transducer cable connector can pass through is 5/8".

Note: Install the transducer before wiring the power cable!

After installing the transducer and power cables, slide the bracket over the hole, then route the transducer and power 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.

Permanent Mount Transducer
The transom mount transducer can be installed on any outboard or stern-drive (inboard\outboard) powered boat.

The "kick-up" mounting bracket helps prevent damage if the transducer strikes an object while the boat is moving. If the transducer does "kick-up", the bracket can easily be pushed back in place without tools.

Always read the transducer installation instructions that came with your unit carefully before attempting the installation. Determine which of the mounting positions is right for your boat. Use extreme care when mounting the transducer, since the transducer location is the most critical part of a sonar installation. If it isn’t done properly, the sonar can’t perform at it’s designed potential.

Location
1. The transducer must be placed in a location that has a smooth flow of water at all times. If the transducer is not placed in a smooth flow of water, interference will show on the sonar’s display in the form of random lines or dots whenever the boat is moving.

2. The transducer should be installed with it’s face pointing straight down, if possible.

3. Make certain the transducer's location doesn’t interfere with the trailer or hauling of the boat. Also, don’t mount it closer than approximately one foot from the engine’s lower unit. This will prevent cavitation interference with the propeller. Typically, the transducer should be mounted as deep in the water as possible. This increases the chance that it will be in the water in high speed and reduces the possibility of air bubble interference.

4. If possible, route the transducer cable away from other wiring on the boat. Electrical noise from engine wiring, bilge pumps, and aerators can be displayed on the sonar’s screen. Use caution when routing the transducer cable around these wires.
