## Description

Product Description Opticron Binocular Rainguards protect binocular eyepieces from rain, dust, dirt and accidental damage. Box Contains Rainguard

Review: superb handling rainguard . - fantastic quality rainguard thats vastly superior to the one supplied with my new Opticron discovery 8x50 binoculars . Even though the stock item does the job its kinda difficult to remove with it being tight fitting rubber , but this deluxe one fits like a dream and is very speedy to remove when you chance upon that elusive sighting . I'd advise anyone buying this model of binoculars to also order this rainguard (45.5mm) at the same time as it makes such a massive difference to the handling . The other thing worth noting is this size also fits the Opticron discovery 8x42's as well , looks like ill be ordering a second one for them now then lol .
Review: A V good product - I have just purchased a pair of these 37mm Opticron BGA binocular rain-guards for a pair of classic Carl Zeiss 10 x 42B (1980's) that I have just purchased second hand. They fit extremely snuggly over the lenses and also attach very easily on the left side to the neck strap. As long as you measure your lens correctly, you cannot go wrong with this robust, stylish product which is also, at under £10 very good value. Andrew Bruce, Dumfries & Galloway, Scotland.

### ⭐⭐⭐⭐ Good enough for non-Opticron binocular
*by S***O on 16 December 2020*

Bought these for my Olympus 10x50 DPS bins and they work reasonably well, much better than the single caps I had originally. Can't lose them as they fit on the neck strap, and they pop off in one when needed, so they do the job nicely, though not a "perfect" fit.
