Looking at a lot of videos comparing several chronographs.
Looks like the MagnetoSpeed seems to be on par with lab radar, usually between 3-10 fps slower, the good reviews I watched charting 10-30 shots showed this trend.
Magneto seems to be easier to carry, you pay once and get everything. The downside seems to be can't use with semi auto pistols unless they have a rail, but I dont care about that and I am not sure how it would work with a revolver (let's say a 5" barrel).
Lab Radar needs a bunch of additional stuff. So let's call it $50-100 over the cost. The positive is the type of gun doesn't matter. But the distance and position relative to the chrono does matter.
Other, cheaper brands, they seem to work OK. I have one, but nothing to compare against and it always s*cks when it throws an error.
So, anyway, what are your thoughts?
