My wife and I with some friends first shot the techno hunt about 10 years ago in the San Diego area. We moved to pa. in ' 96 and have shot the dart system for fun and leagues since moving here. The only ' down' side that I can see is that it has induced target panic in my 3-D shooting.In the ' tunnel' I have it on my mind that the target is going to ' time out' or move to a -3 bad angle, or just walk away and I have found myself really pressing my shots and what I call ' double clutching' . For some reason that has carried over to my 3-D shooting. It has not affected my hunting shots, I guess it is a different game and at the crucial point I am all concentration.
