Just got a pair of GT-31s from www.gps-speed.co.uk and I'm setting them up. I've followed Tom Chalko's setup for GT-31s. However, I seem to remember reading somewhere, probably on Tom Chalko’s Site, that you can set the timing (may have been GT-11s) so there was a 0.25 second or 0.5 second lag when reading. The idea being that combining this with a reading without the lag give increased accuracy. I can’t seem to find the setting, can’t remember what it was called, does anybody know?
Is there anything else I must do in the set-up for the Dual GT-31?
