My buddy has the Primos trigger stick and it isn't beefy enough to use as a trekking pole. You could get the shooting sticks adapter from Wiser precision, connects trekking poles so you can shoot off them.
I own TWO Primos trigger sticks- both the same tall (72" or so) two leg versions. I use them for (dry ground) trekking (in my left hand) fine. I also love that I can throw up my binos on them (standing straight- I'm 6' tall). They can also go low (wide) enough to make a sitting shot too.
What I love: They are FAST, weigh nothing, and they stay where I put them. I hunt with them (1/2 down) on my left hand slightly widened (where they stay fine), rifle slung over right shoulder (or over right shoulder top (hand on pistol grip) when some "action" is happening). I can drop the sticks (widen them a bit more with my left hand fingers on the way down), pull the rifle over and have a steady standing shot in just over a second. I can also use them in a ground blind or in the field (set wide) for an great rest- they are very capable of quickly moving left or right a few inches just tilting the head (to miss that stick in front of your barrel) and setting up a fast shot in this case. The head is "grippy" and the guns stays put even when you tilt the head 30 degrees or so either way.
What I don't like about them: They can NOT get used in water (as in trek poling THROUGH streams or mud). They'll work for that one hunt for a while. But after they get "gunk" in the bottom feet, they will take that gunk up to the release mechanism next time you pull them up to the shortest length (don't do it!!!). Its a PITA to clean them after that (and you can't use oil- have to disassemble them and clean them to a shine and re-assemble). They are fine in rain- clean water isn't much of an issue.
So WHY do I own TWO sets? - because if I "water foul" my first set (it happens on wet Kansas hunts), I just grab set #2 to finish the hunt. At $69 a piece on sale they are affordable.
If they JUST would have used a BRASS release mechanism these would do WAY better in dirty water. The "sticking" problem is due to the "steel release" rusting up VERY fast-- enough to stop them from working smoothly even if you wash the mud out of them. I did reach down and PULL one leg out on my first (5" downpour pig hunt) with them (and I was dropping them in 6" thick mud then- took an hour but they started to "gunk" up and so... I adapted. Made the shot, but took a few seconds to manually extent the "sticking" leg.
You can spend more for sure... but if hunting dry country they work like a charm for me. And if I get a set muddy, I can grab the spare set and hunt on. They are like guns (to me); might have to break them down and clean them some-- but my original set has been under my last 6 or so kills and I've never had to go to the back-up set... yet. But I'm careful to not drop them in water/mud after my first lesson
I'm sure the higher dollar stuff is more durable, but I've learned how to maintain these as just another hunting tool and once cleaned up- they work like new (I've only cleaned my original pair twice- both times due to mud). I just clean them after use with VERY LIGHT oil on a cloth and they are ready for the next hunt.
Yes, I like them!
