When the total weight of your gear is critical keep your options open for long-distance viewing with the help of this lightweight waterproof pocket-sized piece. With the Vortex Doubler you can increase the magnification of any full size Vortex binocular (except the Kaibab) as well as the Recon R/T and Recon Mountain scopes. Take in high-power views more similar to what you'd see through a spotting scope. The Vortex 2x Doubler easily attaches over most Vortex binocular eyecups.
I was on the fence about this but after trying it out I couldn’t be happier with it! It isn’t the same image quality as a true spotting scope; however, it weighs about as much as 12 feathers so is a no-brainer-addition to the optics kit. If you’re even remotely interested in this, BUY IT!!
