If you weren’t successful at finding elk in the first place, does purchasing a Tier 1 Bino make sense?
No, it does not make sense. Why? Because the gear and equipment do not make the hunter.
Here's an example: when I started out as a 12 year-old kid just getting into hunting, I had no idea what I was doing. At that point in my life, my goal was to kill a deer, any deer, with my bow. It took a couple of years, but it obviously happened!
If I were to take all of the very expensive and high end gear I own NOW, and give it to that 12 year-old kid - that 12 year old kid would still not be successful in shooting a deer. Any deer. Even if I had every top of the line piece of gear when I was 12, it just was not going to happen.
However, take all of the crappy gear and clothing that I used when I was 12, and if I were to go hunting with it today, I am very confident I'd be able to kill a deer with that same equipment now. Many deer per season, if I so wanted!
It's not the bow, the boots, or the camouflage patterns; it is the hunter.
It's not the brand of the spotting scope, either.
I've been nearly 100% shot opportunity on elk for archery going on two decades now, using mostly Nikon and Vortex binoculars. (I own Swarovski's as well, but tend to beat the pi$$ out of my optics on the mountains, so the alpha glass is used from a treestand.)
OK, mini-rant over.

The noticeable difference may include sharper and brighter images, an ability to glass for longer periods of time, with less eye strain. This may help you locate more animals on your hunt, but does not come with any guarantees, obviously. If you have the money and will enjoy the purchase, go for it!
