LAST EDITED ON Apr-13-11 AT 00:44AM (MST)[p]I don't use 'em...they're too pork, and superfluous to a 10x type bino/variable power spotter combo
Have looked through a few of em in the field...
I'll just check off the SLC, as I pretty much hate 'Ski glass, though the 15's were somewhat more comfortable to my eyes than any of their spotters or lower power SLCs or ELs, but not comfortable enough for any serious glassing time
Really love the Docter porros, and have good reliable beta that the old Zeiss-Jena BGAT version is even better, but have never had the luck of having the chance to use one
The older Vortex Kaibab is quite nice, and used to be a great value if you could find a 'deal'...not so sure about either anymore
The Duovid 10-15 were optically excellent the one time I had the opportunity to give it a brief run, ain't too convinced on the durability, given the relative fragility of any 'switch' mechanism (have a horror story that goes along with that, but will let the former Duovid owner post it here if he so chooses)....another buddy is ordering a new one off pro form, will post a review after I get a chance to give it a good trial
haven't used any others worth mentioning
Anyway, for all practical purposes, I find the 15s to be too much (weight/bulk) and too little (power) for the way I hunt...I suppose if you only relied on one optic, and I have good friends that do, a good pair of 15s would fill that role quite nicely
Cheers'
