The Swarovski BTX binocular eyepiece is compatible with all three “TX” objective lenses (65mm, 85mm, and 95mm). The BTX 30x/35x Eyepiece Module represents the pinnacle of comfort for long glassing sessions. The innovative design replaces the typical eyepiece of a spotting scope with a dual-eyepiece binocular configuration. Thus, eye-strain is greatly reduced because hunters can glass with both eyes open. The BTX eyepiece angles 45° to the optical tube, so the user’s head is put in a natural viewing position. The BTX provides 30x magnification when mounted on the 65mm and 85mm objectives and 35X when mounted on the 95mm.
Glassing with both eyes improves comfort and dramatically improves your ability to spot game.
