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.

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. ## Frequently Bought Together - Opticron 37mm BGA Binocular Rainguard - Opticron Rubber Objective Lens Covers 50mm OG S Pair fits Models with Outer Diameter 56~58mm --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.kr/products/55680071-31025-37mm-bga-binocular-rainguard-black](https://www.desertcart.kr/products/55680071-31025-37mm-bga-binocular-rainguard-black) --- *Product available on Desertcart South Korea* *Store origin: KR* *Last updated: 2026-05-11*
