Selecting The Correct Type Of Transducer - Raytheon HSB L760 Owner's Handbook Manual

2-2
For the Fishfinder to display depth, water temperature and speed, you must
install the Depth/Speed/Temp transducer supplied with your system.
For full functionality of the radar chartplotter you need to provide position and
heading data.
• Heading data enables the chart to operate in North Up and Course Up
modes. If speed data is also available the MOB function operates.
• Position data is required for full functionality of the chart display.
Full details of heading, position and other data are given in Section .
Before you start the installation, check that you have the correct transducer for
your application, as described below.

Selecting the Correct Type of Transducer

The L755 and L760 Fishfinder displays can be used with any of the following
transducers:
• Transom Mount: Depth/Speed/Temp P65-TM
• Thru-Hull Bronze: Depth/Speed/Temp B44-TH
In addition to measuring water depth, these transducers include a paddle
wheel to detect distance traveled (from which speed is calculated) and a water
temperature sensor.
Applications
Plastic housings are recommended for fiberglass or metal hulls.
Bronze housings are recommended for wood or fiberglass hulls.
• Installation of a bronze housing in a metal hull requires using of a fairing,
available from your Raytheon dealer.
• Never install a metal housing in a vessel with a positive ground system.
Transom Mount Transducers are recommended for personal watercraft and
powerboats with outboard, inboard-outboard and jet drives.
They are NOT recommended for large or twin screw inboard boats.
• Adjusts to transom angles from 3
tapered plastic, wood or metal shim will be needed.
• Designed for operation from 5 –58 m.p.h. (4 – 50 knots).
Thru-Hull Transducers are recommended for boats with straight-shaft
inboard engines.
