Best selling combined Speed/Distance Log and Echo Sounder in standard 110mm square size. Suitable for open cockpit mounting. As with all Nasa instruments – it is excellent value too.
INSTALLING THE DISPLAY
Select a convenient position for the display on a panel or bul-head. The site must be flat and the cavity behind the panel must remain dry at all times. (The cable entry is deliberately not sealed to ensure adequate ventilation. This prevents misting of the display).
Cut a hole in the panel 87mm wide and 67mm high. Bring the wiring through the hole in the panel and connect the black wire to negative and red to positive. (See Figure 1). It is wise to use a fused supply to provide protection should a fault occur. The current consumption is very small, so any supply with at least a 1/4 amp fuse is more than adequate
