AceTech Shooting Chronographs

I had wanted to get a ballistic chronograph for many years and last year there were two that appeared for sale on Amazon dot CA for very affordable prices.
I first bought the AC5000(orange & black) for $75, and later last year I upgraded to the higher end model, the AC6000 which cost $95.
They both function flawlessly and for the price of one "CHRONY" brand chronograph, I had two, one for at home mounted on aa tripo, and one for use in the field that fit easily in my shooting supply bag.

The Acetech AC5000 & AC6000 shooting chronographs are airsoft chronographs, but i contacted Acetech and asked if they can be used for lead & alloy pellets and steel BBs and they assured me that both devices will function perfectly with all AirGun ammo.
