Transducer Installation

The Twinscope comes standard with either a single or twin
thru-hull or with two transom mount forward scanning
transducers. An optional speed/temperature transducer is
also available which will allow the Twinscope to display
current boat speed, surface water temperature and elapsed
distance. The following section deals with the installation
of the scanning depth transducers only; installation
instructions for the optional speed/temperature transducer
are included with that accessory
The Twinscope's uses two 8 element phased arrays (total of
16 elements). In the single thru-hull model all 16 elements
are enclosed in a single transducer. For transom mount
applications (or for the two thru-hull version) two
transducers are required, each containing an 8 element array.
One of the 8 element arrays is positioned to scan vertically
from straight ahead to directly below the boat, while the
other array is positioned to scan forward horizontally from
side to side. The Twinscope has an amazing amount of
capabilities, but it can not perform magic. It can not see
through objects such as your boat's hull. Therefore, it is
important to position the transducer so that it has as clear a
view as possible of the water directly below and ahead of
your boat, as indicated at left.
The scanning transducer(s) must be positioned properly so
that it scans in the proper direction (i.e. from in front of the
boat to the bottom below). The sketch at left shows the
proper orientation for both the transom mount or the thru-
hull transducer(s). NOTE THAT ON THE TRANSOM
MOUNT TRANSDUCERS, THE ROUNDED SIDE
MUST POINT FORWARD, AND ON THE THRU-
HULL TRANSDUCER, THE MORE BLUNT AREA
MUST POINT FORWARD.

General Considerations
DO NOT CUT OR SPLICE YOUR PHASED ARRAY
TRANSDUCER CABLE OR REMOVE THE 9-PIN
CONNECTOR BECAUSE THE SYSTEM
PERFORMANCE MAY BE SERIOUSLY
DEGRADED. THIS ACTION WILL VOID YOUR
