[QUOTE="Shootin4fun, post: 1208135, member: 28741"] Well, it sounds like there are some that made it out to users. How are you guys liking them? I'm sure they must be awesome after having to deal with the problems of lesser technologies. After using standard screen type of chrono for several years now, it is apparent to me that this technology has a couple of main important advantages over others that have been in use so far. This one and the magneto get past the problem of inconsistent/inaccurate readings due to the angle of the bullet travel not being perfectly parallel to the sensors, thereby inducing computational errors because of distance between sensor variances. While using mine it has occurred to me that if you are 3 degrees off parallel, that's almost 1% change in distance between sensors, so 3000 fps turns to 2970. Man it took me a long time for that to really sink in. lightbulb Hmmm...so if I'm tilted up 3 degrees on shot and down 3 another that's a 60 fps difference when there was no difference in true speed! What does that do to your stats??? Now I have to throw away all of my records...kidding, but they are now looked at with a jaundiced eye. I guess I have to assume the highest velocities attributed to a given load are the true ones where I had everything lined up perfectly. All this to shoot a deer or pigs at 600 yards, LOL. [/QUOTE]
