Section 2: Installation & Accessories
Preparations
You can install the unit in some other order if you prefer, but we rec-
ommend this installation sequence:
Caution:
You should read over this entire installation section before drill-
ing any holes in your vessel!
1. Determine the approximate location for the unit, so you can plan how
and where to route the cables for the transducer, any sensor and power.
This will help you make sure you have enough cable length for the de-
sired configuration.
2. Determine the approximate location for the transducer and its cable
route.
3. Determine the location of your battery or other power connection,
along with the power cable route.
4. Install the transducer and route the transducer cable to the sonar
unit. Install the speed or temp sensor, if applicable and rout the cable
to the unit.
5. Route the power cable from the unit's location to an appropriate
power source and connect it there.
6. Connect the transducer/power cable to the unit and mount the sonar
unit on the bracket.
Transducer Installation
These instructions will help you install your Skimmer
transducer on a
transom, on a trolling motor or inside a hull. These instructions cover
both single- and dual-frequency Skimmer transducers. Please read all
instructions before proceeding with any installation.
Your Skimmer transducer typically comes packaged with a one-piece
stainless steel bracket for mounting it to the transom of your boat. The
optional trolling motor mount uses a one-piece plastic bracket with an
adjustable strap. These are kick-up mounting brackets. They help pre-
vent damage if the transducer strikes an object while the boat is mov-
ing. If the transducer does kick-up, the bracket can easily be pushed
back into place without tools.
Read these instructions carefully before attempting the installation.
Determine which of the installation methods is right for your boat.
