Matrix 2002 LED w/ SLAM bolt, SCM LPR, Evil Detonator Inline reg, Centerflag 201 88/4500 tank. and 9 other guns......
Reads out to 1 tenth of a foot per second,
Needs full sunlight.
easily shot by an uninformed user.
I prefer the pro chrono because it works in low light better (but still not indoors) and the splatter guard for it is MUCH better. If you want the extra info of the 1 tenth of a foot per second readout, and you are careful to shoot well over the unit AND play in a sunny area, you should have no problems with this unit. The problems arise when your friends tend to shoot to close to it, not realizing they can shoot a good foot over it and it would still work. I suggest making your own splatter guards from little pieces of clear plastic because the ones they sell for it are only good if you don't want to fold it up.
Be sure to cover the readout with a thick piece of clear plastic because I myself have shot out the display of my pro chrono with a sensitive electronic trigger gun....
A very nice well built feature laden unit that was NOT designed for paintball but will work well if you are cautious with it.
