Funny you should mention Bipod. . . that is exactly my next order of business! What constitutes features to look for? At first blush, absolute rigitity and impervious to the weather seem minimal starting points. Adjustability?, high strength-to-weight ratio, parts availability, product available in Canada (That has become a more than important criteria for me to insist on, as of late)
Well..... There are 3 levels of cost, IMO
You could get a champion pivot traverse for about 80$ and it'll likely be fine. I have one. It's pretty good.
Then, the Harris, at about 120-150$. I think most would agree they're the gold standard and most common. They're really useful, and fairly light. I have several. They look a little utilitarian.
From there it goes stratospheric.... Atlas and LRA are the two that come to mind and you're looking at 4-550$. They are beautiful pieces of machining art, light, and rigid. I'm looking at one of this level for my modern hunter.
Things I've learned are important are:
- the ability to cant/pivot. If you're on uneven ground you'll need it.
- panning is nice, but not needed.
- choice of height: bench is 5-9", prone is 6 (for a little person) and 8-12 if your 6 foot-ish. For hunting i'd suggest a Harris 12-25. It's low enough for prone (barely), but high enough to use kneeling to get you up out of the snow and grass
- get a core-lock lever from coretac. You crank it down and it makes everything solid. It's about 20$.
All of these are available in Canada, at reasonable prices despite the sh!te dollar.
