Free: Contests & Raffles.
Honestly it depends on what and where you are hunting. I think the best way to go is a high quality pair of binos 10x42 on a tripod and a spotter. The 10x42 allows you good fov to find your deer or elk. Then switch over to your spotter to find out if it's worth the stalk. I'm running a maven setup with an outdoorsmans medium tripod and a pistol grip, I'd like to get a panhead eventually. It's absolutely amazing the difference glassing is with your binos on a tripod. I can pick out deer in no time on my tripod while my buddies search forever (freehand) trying to find what I'm looking at.
I use 15x Swarovski's 95% of the time. I have a 95mm and 65mm Swarovski spotter and always have one or the other in my pack for detail work.I recently bought a BTX which allows two eye viewing at 35x. For big country where I am day hiking, these will be tough to beat. I will use the hell out of them in Eastern Nevada in a couple of weeks.I just got back from a high country hunt in Colorado where my 15x binoculars paid huge dividends.
I'll give an update, bought a Vortex razor, gave it a shot, and returned them. It really was not comfortable for glassing long periods of time. I also doubt I will ever want to pack it around. I'm gonna give bigger binoculars a shot
