I know this is a very old thread, but I just wanted to post what I put together as a trekking pole/monopod for hunting. I use this for everything from Vanguard 10x42 hunting binos to Celestron 15x80 big binos and it works well. It is a 61" monopod, 7"-13" adjustable top extension, tiny little pan and tilt head, and a Staoptic generic bino stud mount (very similar to Outdoorsman product as far as function and quality at around 10% of the cost). All totaled, everything cost about $85 for the entire setup and weighs about a pound and a half. A little heavy as trekking poles go, but very light for all the funtion I get out of it. Being 6-3 and 250, a heavy duty trekking pole is often just what the doctor ordered anyway. My entire setup is about half the cost of an Outdoorsman bino mount and stud alone. Outdoorsman has great products and I like them, they are just proud of them. Fully extended height is around 80". Works great as a trekking pole and I can quickly stick my hunting binos into the stud mount without even detaching the binos from my bino harness to quickly glass a hillside, ridge, or canyon while I am on the move. I usually carry a carbon fiber tripod in my Kuiu daypack for longer sessions from a hilltop or ridge location. If it is a particularly rugged approach (as they often are in southern AZ), I can carry this as my only glassing option and pack light and still get the job done. I keep one hand in the carry loop, and can grab my rifle and take a shot without even dropping the pole, it just hangs from my arm while I shoot.
