I have a Beta Master Pro Chroney, that I have used for several years for reloading. I wanted to use it to check my arrow speeds but it will only work, once out of every 5 or 6 shots, the rest of the time I get an error message or no reading at all. Has anyone had problems with a chronograph that works well on bullets but won't work with arrows? Or am I doing somthing wrong?
Thanks
