After a Chronograph which I can use indoors (under LED lights), which I can use by itself OR can connect it to a computer to do a complete shot string, and a print off.

Ideally compact, I've had Chrony ones with the two light diffusers above but found them a bit of a faff.

Mains powered is ideal, not really fussed on it being battery powered.

I'm leaning towards a SKAN, but from what I've heard and read the software is extremely dated. Unsure whether it will work with Windows 10 (It mentions Windows 95, and at an extra £140 over the standard non computer version I'd hope it to be fairly decent. I will be calling them in the next couple of days, as their website is pretty useless.

Any Chronograph suggestions, or anyone had any experience with SKAN software?
