I just got a Kuiu and it should be super nice. No strain on the neck like a lot of bino holders. There is a small pouch on each side that would likely work for gps and possibly a rangefinder (depending upon their sizes). I think I would have gotten a size a little larger so it was a little easier to get them in and out but I imagine it may loosen up after use. It also comes with a small waterproof cover as well as an attachment for using without the large pouch (to save on weight and bulk. I paid around $90 for it.
