The Rangefinding ELs don't have Swarovision and aren't the equivalent optically. The belly on the bottom of the barrels of the binoculars is worse to look at than actually to use. The only 2 features I preferred of the HD-B were the rangefinding button position and the rangefinder itself. I didn't get the HD-B for the ability to enter ballistics into the binocular. If that means something to you, it has one more preferential feature. I am not amused by the technical ability of the HD-B. I am just interested in the optic and rangefinding capabilities...
