Had a set of those and my only issue was keeping the bolt at the right tension level. It seemed to always work loose even with a nylock.2 - 4' long popular survey laths with a hole about 8" from the top and a 1/4-20 bolt with a couple washers and a lock nut. lol
Been using them for 35 years.
I really want to try one of these!Depending on the vegetation/terrain I'll either run a TBAC bipod with leg extensions or a RRS 24L tripod. I find myself taking more shots seated or kneeling behind the tripod.
