15x binocular - Vortex Vulture HD 15x56 Binocular

I conducted side by side vision test of this unit and the Kaibab 18x. The light gathering at dusk was better with the Vulture. All Vortex optics are very impressive and a value at more than the cost. These binoculars can be hand held for a little time, but are MUCH better when tri-pod mounted. The adapter is included.
