When browsing around it seems not all are equally impressed with the Bushnell Discoverer 7x42, some prefer Nikon monarch 8x42, Some say its even mediocre, other praise it, but not substanially better than the Monarch. Maybe i have read reviews of early versions, without the XTR-coating?
At the same time The Bushnell Custom compact 7x26 (pre-elite version, now its got XTR-coating), gets praised over the Nikon Monarch 8x42 for being more bright(!!) sharper, better long distance resolution AND with lesser eyestrain view.
With that Monarch generally being praised as good in the pricerange, the custom compact must be insane then!
Seems that Bushnell custom compact is even better than the discoverer then??
Bit odd comparison, but that is what i am "reading".
Correct me if I´m babling..

I don't think it would be possible for the 7x26 Custom Compact (with its 3.7mm EP) to actually be
brighter than the 8x42 Monarch (with its 5.25mm EP) though it might appear as such simply based on the difference in FoV (363 ft for the Compact and ~330 ft. for the Monarch.) The wider FoV might give the
illusion of increased brightness. Not even their XTR coatings, regardless of how good they are, can overcome a full 1.55mm difference in exit pupil size. I would venture that it
might be possible for the Custom Compact to be brighter than say an 8x30 or 8x32 binocular as the exit pupil difference is only between 0.05 and 0.30mm and I would think this difference MIGHT be able to be overcome IF the XTR coatings are significantly better than those used on the other binocular.
Basic physics suggest that (unless the bigger binocular is made in an inferior way) the smaller binocular does not have the potential for being sharper, offering better long-range resolution, or providing a more relaxed view than a larger binocular. Its physical size also requires most people (including very small people like me) to scruntch their hands together to use it, which can become quite uncomfortable after awhile.
In reality, even with the "blessed" 7x magnification coupled with a very comparable exit pupil, a similar FoV, and a smaller size/weight than even many 8x3* class binoculars, the 7x26 Custom Compact has never exactly taken the binocular world by storm. So, although it is a very good and perhaps even one of the very best compact binoculars ever made, it still IS a compact and it trades off some performance for its smaller size.
I am a huge fan of compact binoculars (including the Custom Compact) and I keep a compact binocular in my pocket almost all the time no matter where I am. I am not, however, trading in my full-size binoculars any time soon in favor of a compact as a primary/only binocular. My wife on the other hand, could be perfectly well served for the rest of her life by a compact binocular as her performance demands simply don't compare to mine.
Whether the performance level the Custom Compact
does offer is good enough for your specific needs, is up to you to decide.
