Just get a used Scatt USB with the standard programming, there is still even much too much geek-dome on that, all you need is what appears on the basic trace screen, that's all I use coaching right up to with International shooters.

I've used one for coaching for very many years, almost since Scatt came out, a wonderful tool that tells all! You can't hide from the facts.

But they do need an experienced and perceptive eye to get the best knowledge from them, so best used with an experienced scatt aware coach, its why so many end up being bought by shooters, used half a dozen times and then gather dust, and why there are always used ones for sale. There's a USB one on Stirton now for the average going price.

Best of luck, and have fun.
