LMBR Chronographs Anyone?

Screwed up my Air Chrony MK3 (my i door chrono) recently. Had an accident that caused a slug to strike the reflective metal plate, and the resultant little dent in turn was enough to throw off the calibration for optical-based velocity readings. I tried to make a new, flat reflective surface using aluminum tape and then a sheet of fine stainless, but the readings just went north or south of what my Lab Radar was reporting.

So I ordered an LMBR R2H today, not realizing that there were two other models. Does anyone know if thr R2H is the better option in general, and for those that have any of the LMBR chronos, are you happy with it? Thanks in advance 👍
 
I just looked it up, R2 is for Airguns, R2A is Airguns and firearms, R2H is both of these and also includes Archery. I think you bought the top of the line. Where did you buy it from?
