Laser Trace - The current system does do a laser trace much like the Scatt system does. The big difference that in trace mode we don't detect the pulse of a laser shot. (Something we may be working on the future). So if you just want to see how steady you are through pulling the trigger, they system works well for that. We also work with any firearm that is putting out a steady laser, even laser bore devices will work for this.
Laser Hit detection - While doing this we see the short laser pulse and mark the location on the screen and store it in the database. This allows you to do realistic dry-fire training. We the laser dry-fire training you can work on your sight picture and trigger pull.
Live Fire Hit detection - In live fire mode, we "see" the holes that are put through the paper and mark those as hits. You are using the same system and can compare live fire vs dry-fire training. So you can identify mistakes you are making that are not just trigger pull or sight picture.
One of the biggest advantages with the system is that it is easy to set up and use and it is just sits their watching what you are doing. Shooting session after shooting session it is your silent witness to what you are doing and the bad or good habits that you have. It knows the location and timing of each shot that you have done. If you are pulling shots when you rush the shot, the OCAT System will show you that. If you are anticipating recoil, the OCAT System will show you that.
Now there was a question about the version "levels", I am guessing you are asking about the different kits and their capabilities. There is really just two different capabilities, Laser Only and Full versions of the software, everything else is options and goodies. The laser kit of course comes with all the stuff you need for starting out with laser (software can be upgrade to the full version for the difference in the software prices). The basic kit is all you need if have a compatible spotting scope. The Standard kit is everything you need to get going. The deluxe kit is the kit for people that want everything in one bag, has a lot of goodies and extras.
A computer is required for using the system but most people have those now days. For laser-dry fire a desktop computer will work just as well as a laptop, we have someone that is using their desktop for laser-dry fire.
Hopefully I have answered those questions. If you have anymore, or I didn't really answer what you asked, let me know.
