Clamp it on the webbing, not the entire strap, should fix your problemHave the pro....just make sure you order the long clamping bolts as well. I could have sworn i read the PRO comes with these....well mine didn't. Won't fit on my kifaru shoulder strap....barely fit on my previous eberlestock strap.
I have one and like it a lot, highly recommended.
I need to see about getting a QD plate for mine as I hate having to swap out it out to put on the tripod. Anyone have a recommendation on a QD plate that works well with it?
