I just ordered one of these:
US Chargeable Ballistic Chronograph High Accuracy Arrow Velocity Meter Measure
Off of eBay, amazon has them also. Has anybody played with one of them and any feed back on them?

Apexpredator look here:

35 $ on Amazon vs $28 on eBay here:

bandg that is meters per second which in feet per second (what pellet guns are normally measured in) would be 3-3300 fps, which covers most of the pellet guns I shoot.
Odoyle, I am not sure why you put the calculator up on your post, to inform others reading this post how to find out the conversion?
1-999 m/s equals 3 -3,277 f/s (rounded off) (basically multiply m/s x 3 to come up with f/s.
Thanks for the link.
