I'm selling mine, too, though. And not for a v2 but rather an acoustic chronograph. Magneto speed is accurate but it affects POI in a big way so you can't shoot for groups or do load development at the same time. The acoustic chrony is just as accurate and the same price.
Not too sure about that... did you see the data posted in the other thread? In a comparison of the SuperChrono and Magnetospeed against an Oehler, the Magneto speed was more accurate and consistent.... assuming the Oehler was accurate. and no reason not to assume that.
The SuperChrono's inconsistancies "may" have been because it was set up closer (I set it up) than the recommended distance by the manufacturer, for magnums and high velocity rounds. Coincidentally, it was the higher velocity rounds that were least accurate compared to the Oehler. I plan to have both the V1 and Superchrono and when I get the V1, I will be conducting another test with the SuperChrono. One good thing was the ES's recorded were close to the Oehler and Magnetospeed.
When I'm developing a load, I can use both and determine the difference for that load, i.e., SuperChrono records velocity for that load 50 fps slow than the Magneto. Once I know the accurate velocity of the load from the Magneto, I can use the SuperChrono for all other velocity data for that load by applying the difference factor and not be concerned with POI shift. I can also use the SuperChrono anywhere down range to confirm velocities down range. That will help me fine tune BC's and know where my effective range is limited to.
The fact you don't have a readout on the bench is a draw back, but I've been dealing with that for years anyway. Also, Steinert is coming out with a wireless bluetooth version
If when testing with the SuperChrono properly set up, it proves to be consistent with the Magnetospeed, well then everything is great all around.
