What a great idea!

I know that would help me with eye strain after looking through a spotter for 4-6 hours straight. Can't afford it, though.

Why would you use this over a double spotting scope set up? For this price you could buy 2 Swarovski spotting scopes

Are your eyes wide set enough to use two spotting scopes with 85mm objectives?

Would you enjoy panning, canting, setting diopter, and focus on two spotters each time you move both of them. And that's after you got both of them viewing the area you want to view.

Based on your comments you don't know what I'm talking about. I had a guide use something like this and it was awesome.

Big Eyes

Correct, I didn't know.

You never mentioned hardware to cant, and tie them together.

Skylar what do you see as the benefit? Weight and size? It seems like everything else would go towards a dual spotting scope setup.

Weight and size are pretty huge benefits. Heck, the little headrest alone is pretty dang nice.

I see this to be more beneficial over the Big Eyes design that we formerly offered, because that is no longer available. The man who originally came up with that design no longer offers it for sale.


This set up will be considerably lighter. In the video, it also seems more accommodating to peoples eye set. We should see this attachment within a couple weeks and I will have more information on it.

Well time to update spotter. Swaro got it right this time. Probably not near the field of view of the prominar but probably a lot more back friendly and being modular dual purpose is extremely nice.

Hey BOBO just pick up a couple in case you lose one. I'll field test the spare for you to make sure it's working right.

I'm not sure about the headrest feature being useful for hunting. Leaning or putting pressure on the spotter seems odd. Light touches move the scope at long range even with a good tripod
