Chronographs, shields, tripods.. more stuff for me to carry out to the range and then back to the house. I have it worked out now to one big load, but two small loads would work as well.

Now how far do you put that thing in front of the rifle stand? Also you have to shoot through the ears or the V of that thing.. right? All of this is battery operated of course?

That box looks easy enough to make. I have a camera tri pod some where in one of the gear closets... But then I would actually have to compare all the numbers, and I hated statistics classin college..
