SOUND. I shoot and hear the arrow hit. I say, "Gee, that was fast". How many tims can you use one for any real value? If I need to know I go to the archery shop. Of course that's in Maryland now.[&:]
I use mine all the Time. Finding the sweet spot on cam rotation, locating speed nocks on new strings. Checking different arrow setups for speed, KE, etc. Takes a lot of guess work out of things. I like having mine handy. The shop is an hour away, at the price of gas it wouldn't take long to pay for the Chrono
