Which Amazon Chrony?

I have this... works great overall, in ALL lighting conditions, how not super flexible as you have to set yourself to shoot through that hole. Lol. Not a big deal at all. Its a backup to my FX unit. Also use it when chrony shots from my springers. Comparing results between the FX and this unit, FX is about 5fps higher. Again no big deal the resulting differences are pretty consistent for each.
