I need to measure accurately the velocities of 6 loads through 4 different rifles.

I freely admit I shot my latest chrono ...

Because of that I would like to rent from someone or somewhere a radar like chrono (Garmin, Athlon) that will sit on the bench rather than in front of the muzzle (so I don't risk shooting it, again...).

However I cannot justify spending $500+ to chrono 6 loads...

Does anyone know of a range that offers that service?
Or, alternatively, loan me one (I will leave an adequate security deposit, cash) for a couple of days?

Testing would take place at the Silver bullet Shooting Range in Wheat Ridge and Golden Gun Club in Watkins.

I would pick it up and return it at your location, of course.
