[QUOTE="P7M13, post: 2000822, member: 94154"] True words. The light curtain types are useful for pistol loads and arrows. However, they are a PITA to set up, need light to work, and the light filter "bonnets" have sucked on each one I've used, especially on my Chrony Pro Beta. I built a new screen, keeps the sucker dry in rain, and works great in the '8 months out of the year', heavy, gray skies here in the PNW. That said, it still sucks. I get a lot of "DNR" data points. Magnetospeed is much nicer, doesn't drop any data points, but you cannot use it for pistols. In retrospect, I wish I had spent the $200 more to buy a labradar. On the Magnetospeed affecting your accuracy, it sure does. Not only will it affect the barrel harmonics, if you vary the adjustment of the blade off the front of your rifle, the closer to the bore, the more it will cause a bullet deflection upward. Wouldn't believe it if you had told me, but mounted my magnetospeed close to the bore. Didn't hit it with the bullets, but it was causing them to deflect high enough that they hit the first "bullet deflector" wall at my club. Certainly a WT* moment. Empirical data, dude. It doesn't lie. Sure you shoot more bullets, but that's fun! Of course it will be dead on, but the target will be in the wrong position. It's a Schrödinger's Cat kind of problem. Didn't see it in your list, but you can also verify the accuracy of your projectile ballistic coefficients. Using a Labradar, you can also see how the B.C.'s change at different velocities. I have always appreciated how Sierra publishes that data. [/QUOTE]
