1.1 General
The Pathfinder PLUS Radar/Chartplotter comprises the SL70MRC (Mono)
or SL70CRC (Color) display unit, scanner unit and associated cables.

The display unit is waterproof to CFR46 and can be installed either above or
below deck.

• Four soft keys (unlabeled) whose functionality changes

MAP NT

chart cards
The display and keys can be illuminated for night-time use.
Scanner
The Pathfinder Radar is supplied with a scanner unit which illuminates targets
with microwave energy and then collects the returns from those targets. The
scanner includes a sensitive low-noise front end receiver, and a variety of
clutter attenuation controls to maintain target resolution.
The scanner is adjusted and operated from the display unit, so these details are
provided in this Handbook. It can be switched between transmit and stand-by
modes. It also has a power-saving timed transmit mode which pauses between
bursts of transmissions.
Installation of the scanner is described separately in the Scanner Owner’s
Handbook.
