I've been using a pair of the HD-B's in 8X, since April. They've proven to be top notch so far. The program has been spot on for both my 6 Creedmoor, and 6.5 SAUM. I've used them up to 11,000', down to 2000', from 20*F to 100*F. Great tool! No more fumbling around for a range card. Under perfect conditions, I've ranged out past 2000 meters with them. The ergos and optics are what you expect from Leica..

Luck....is the residue of design...
