MagnetoSpeed Sporter chronograph

I use the Magneto Speed V3. It has a broader sensitivity adjustment which I found necessary with the smaller pellets to get reliable readings. In other words I have not used this particular Sporter version but would question if 3 levels of sensitivity would be enough adjustment to read the pellet. I will say that the price isn't bad and that the reliability on what I use from them gives good results regardless of lighting and conditions.
I have heard that some complaints of accuracy with some larger powder burners as to FPS but I have used my set up and have had great results.
