there are two models that I know of. The earliest is a one peice plastic houseing . I have this model and it works just fine. It is not my only crono but for the quick load development and cking power factors it works very well. Modestly priced to boot!
I wouldn't hesitate to pick up a used one if the price was reasonable.J.Michael

They usually buy several a year. I think they get them pretty inexpensively, and that's a good thing, cause let me tell 'ya, they're not "bullet-proof." They're not the most convenient, but they work well and they are easy to use. My archery club also uses these, and we're pretty cheap. We made a home-made light kit to use it indoors for a few dollars, works great. I would give them a "thumbs up."

They are a bit simplistic but they work well enough. The serial Data port on the newer ones might be better than the IR printer one that was really hinky. As noted...not bullet proof...my third one is still going after collecting an errant .22 round...I managed to repair it and tested it for function and accuracy. The other two succumbed to high velocity plumbism.
