This is the unit I am considering if I don't do the Caldwell set up. Wiser bayonet mount: https://www.wiserprecision.com/products/chrono-mount

I have seen groups affected and have also had the unit slip which ruins a string of velocity tests. I also have a table top tripod that could work for this as well.
