For all EL 32 and SLC model Swarovski binoculars (except 8 x 30 WB). This handy gadget will double the magnification of your binoculars in an instant. For example; the booster converts the SLC 15x56 WB into a monocular telescope with 30x magnification. Easy to assemble: simply unscrew one of the two twist-in eyecups on your binoculars, and screw on the booster.
The booster is boxed, in new condition and is a genuine UK Import. It comes with a neoprene belt pouch and SLC 10x42 adapter ring, with original instructions and purchase receipt (all like new).
In excellent condition, would make an ideal Xmas present.
Looking for £200 including postage, or you're welcome to view / collect from Wiltshire (near Salisbury).
