This device screws into the threads that are normally used for your binocular's eyecup to double the effective magnification. An 8x binocular becomes a 16x power unit, a 10x turns into a whopping 20x and so forth. Works with all EL series binoculars and every SLC series binocular except for the 8x30 model. Definitely a handy accessory to keep around. You'll get more use out of this if used with a tripod adapter, pan/tilt head and either a monopod or tripod-but of course it can be used for briefer studies upon its own.
