Phedon,

 Well, I have one of these Nikon CoolShot AS and it sure measured the height of the planes at West Baden and Kent very well. Mike Kirda borrowed it once at West Baden, I think. I do not recall him telling me that there were any problems when he tried it out.
 

 Bruce Kimble brought an older Bushnell Rangerfinder to Kibbie last summer. It was a version used for hunting and only measured inline distances (no angle measurements and trig calculation). He was measuring the height of the planes by standing directly underneath the flying model. Many of the F1D fliers in the trials asked Bruce to measure the heights of their planes to help setup the vp prop hubs. Bruce was iin great demand so his measurements must have been accurate and valuable to the fliers. This is where I got the idea to use a forestry version of a similar rangefinder so as to be able to stand off to the side and still measure the heights (the forestry versions have an inclinometer and use trig to get the heights). I borrowed the a Nikon Forestry Pro to test before I bought the Nikon Coolshot AS. BTW, the Nikon Forestry Pro has dropped about 50% in price recently and can be bought for around $400 US. However, the CoolShot AS allows one to be a bit closer to the target (4.5m rather than 10m) and has greater range (550m compared to 300m). However, the Forestry Pro has a "feet" output put mode where the CoolShot AS only has meter and yard modes.
