I use 15X MeoStars. They`re pretty impressive when covering big country but I can`t do the tripod thing with them, unless I am looking at one spot and am not gridding an area. That is with any bino though, not just the 15Xs. It torques my back all to hell, in all kinds of weird angles when pivoting and panning.

I`ve gone back to bracing my elbows on my knees when glassing big areas and keep the tripod with the spotter.
