I purchase a MagnetoSpeed Sporter Chonograph as an upgrade to my shoot through unit. Just found out that it’s not design for Airguns. The rep at MagnetoSpeed did say for larger pellet .25-.30 cal it’s possible if the sensitivity is set at high 2. Before I try it, has anyone on the forum own or tested this unit on Airguns.
I have the Magnetospeed "V3 Ballistic Chronograph" with Firmware version 2.1.03. I assume it is different from the "Sporter" model you wrote about, but cannot say for sure..
I was able to set unit "Sensitivity" to "11" and easily chrono both .22 and .25 caliber PCP guns with pellets raging from 18 grains on up. If I recall correctly, the unit was a bit hit or miss with my .17 spring guns.
I've used the unit a few times in the last few weeks after a two year hiatus, and am re-discovering how much I like the unit. Specifically, I don't have to mess with sunscreens, adequate lighting, and barrel to sensor alignment issues.
Best wishes.
