Bypass the bridge all together. >Just thinkin, >Joe Goss Interesting idea, Joe. Getting enough distance between the laser and the target might be tough, unless you bounce it off a mirror to the ceiling, or to the opposite corner of the case. The longer the baseline, the more accurate the reading. You'd have to get the increments bigger than the laser dot, and a scale calibrated for that particular baseline distance. That's where reflecting to the ceiling (and back down to the scale, where it is reachable and can be positioned for zero) might be handy. A tad cumbersome for field evaluations though... Ron N
