I don't have an interest in buying these binoculars at $179 plus shipping but I have purchased many, Many things from Sportsman's Guide and they have good descriptions and excellent customer service should something be wrong when your shipment arrived (damage, doesn't match descriptions etc.)
I understand they have already sold out of the 10x42 model at this price. I've looked through the 7x42 for an hour or so and it seemed bright and sharp. Since I don't use them or the 8x42s I can't make a personal recommendations but these 2 binoculars seem highly regarded.
I have recently obtained a pair of the Yukon Futuro 7x50Ws and I compared them to a pair of Zeiss Jena Binoctar 7x50W I have that are fully multicoated and a pair of Zeiss Jena Jenoptem 7x50W which I think have fully coated prisms and fully multicoated lenses. I immediately went comet searching for Holmes and then used these same binoculars at dawn to search for turkeys in my back pastures. These Yukon 7x50W binoculars are amazing, and as good as either (15-16 year old) Zeiss Jena binocular for allot less money.
I dislike individual eyepiece covers that come off but there is a reason for them. (I'll have top find a routine that requires me to put the Yukon covers away every time I use these bins). The objective covers are the same flip-away style that the other Futuros have. The eyepiece lenses are 24 mm in diameter and the eye relief extends back 26mm with moveable eye cups (so the eyepiece covers are very large). I've seen another version of this same bin that was less satifactory with only 17 mm of eye relief and flip-away lens covers over 17mm eye lenses. This inconsistancy in production bothers me but since Zeiss did this (made various versions of what should have been the same bin), and some Yukon bins are copies of Zeiss Jena bins made on Zeiss tooling after WW2, it might explain why this is happening.
The view of 400 feet at 1000 yards was confirmed using marked fenceposts in a pasture the correct distance away. The image is incredibly sharp all the way across the field (80% sharp and barely soft at 95% at least on fenceposts with a bit of pincushion on the edges). There was very little if any flaring, and stray light was quite minimal even with a brightly lighted dawn sky and shadows on the ground in the pastures.
Saw a number of deer that will later sleep in the high weeds as they were feeding. There was a prowling fox that probably made the turkeys wary because I only saw one and she was headed away from our ranch up a weed covered hill. The Blue Jays were pretty busy though as they like feeding on ground seeds before the raptors start floating in the sky. A few crows came up to search for milo that grows within 70 yards of the farmhouse and they were extremely well defined even though at dawn they are black against dark shadows. Their eyes are pretty interesting to watch as they eat. I've only had these bins for 2 days but I got them at Optics Planet and for just about $100 they are a spectacular performer. They are a bit heavy at 950 grams and you must be aware of your surroundings because the flip-away covers on the objectives can snag things. But they were great yesterday checking the turkey vultures and raptors who prowl our skies overhead. An excellent bin and an excellent value.
