Installation Instructions for

Transducers
Single- or Dual-Frequency
This instruction booklet 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.
Read these instructions carefully before attempting the installation.
Determine which of the mounting positions is right for your boat. Use
extreme care if mounting the transducer inside the hull, because once it
is epoxied into position, the transducer usually cannot be removed.
Remember, the transducer location and installation is the most
critical part of a sonar installation!
The smaller single-frequency Skimmers typically use a one-piece,
stainless steel mounting bracket. The larger dual-frequency Skimmers
typically use a two-piece, plastic mounting bracket. The trolling motor
mount uses a one-piece plastic bracket with an adjustable strap.
These are all "kick-up" mounting brackets. They help prevent damage if
the transducer strikes an object while the boat is moving. If the trans-
ducer does "kick-up," the bracket can easily be pushed back into place
without tools.
Depending on your sonar unit's connectors, your transducer cable may
also have the sonar unit's power cable attached to it. If that is the case,
be sure to install the transducer first, before connecting the power cable
to a power source. See the instructions in your sonar unit's manual for
connecting the power cable to a battery or other power supply. (Lost your
manual? Most current product manuals are available for free download
from the manufacturers' web sites. See the back page for web links.)
Recommended Tools and supplies
If you prefer the option of routing the cable through the transom, you will
need either a 1" drill bit or a 5/8" drill bit depending on the type of cable
connector (see figure at top of page 11). Each transom mount requires use
of a high quality, marine grade above- or below-waterline seal-
ant/adhesive compound. The following installation types also call for these
recommended tools and required supplies (supplies are not included):
Single-frequency transom installations
Tools include: two adjustable wrenches, drill, #29 (0.136") drill bit, flat-
head screwdriver. Supplies: none.
