Don’t waste your money. ### ⭐⭐⭐⭐⭐ Excellent highly visible Scuba/Snorkel surface buoy *by B***. on 6 December 2023* Excellent highly visible Scuba/Snorkel surface buoy to warn boaters of underwater activities in the area. I use this for jetty and offshore dive spots. The metal 100ft thumb reel operates very smoothly, is strong, flat and orange (high viz) to avoid enranglements of cord. Buoy can be inflated from bottom (my preferred method), by mouth or BCD regulator hose. I prefer to save my tank air and just inflate it by mouth. No issues with the product at all. I did use a bigger snap-clip, but there was nothing wrong with the original (just preference). Highly recommend this safety device to warn boaters of Scuba/Snorkeling in the area. ## Frequently Bought Together - Seafard 4ft Scuba Diving Open Bottom Surface Marker Buoy (SMB) with 49ft Finger Spool Alloy Dive Reel and Double Ended Bolt Clip Red - Scuba Choice Diving Dive Writing Slate 6 x 4 with Graphite Pencil --- ## 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.es/products/665563675-4ft-scuba-diving-open-bottom-surface-marker-buoy-smb-49ft](https://www.desertcart.es/products/665563675-4ft-scuba-diving-open-bottom-surface-marker-buoy-smb-49ft) --- *Product available on Desertcart Spain* *Store origin: ES* *Last updated: 2026-06-05*
