Brycey boy I suggest you look at the cheapest version that Ace sells. Clint gave me one and I love it. Its super simple and only works for wood or boo. It mounts to the wall.

Make one yourself Bryce.I made this one years ago from a book called Bow Making Accessories.Very quick accurate tester.A dial indicator costing 20.00 was used with spare pieces of wood laying around.Nice on and off switch with a nice zero out option.26" width between the posts[not sure if that's ISO] with a 2# weight to hang onto shaft.

I use a micrometer attached with a clamp, and made my weight with lead ingots, and found the charts on line.  Set it up to be not collapsible but it can easily converted to breakdown mode.  I think I am going to make an arm the will support fletched arrows, too!  I can send you a base and upright (walnut)' you  just have to make and set the yardarm, and mount the pegs.

Thanks Chris I’ll look into it.
The one I have now is one that I made. It’s accurate as all hell but I hate having to check my deflection sheet the cross reference the actual spine of the shaft.

My dial indicator reads out MM to the poundage of the spine shown on a converstion chart taped onto the spiner for very quick reference.Easy peaszy and very fast.
