Der Preis ist ebenfalls viel zu hoch, aber die Boje erfüllt in allen Maßen das was sie soll. Die spool macht einen hochwertigen Eindruck und alles funktioniert einwandfrei. Die Boje hat eine gute Größe und mit den Metallplatten ist es perfekt. Der Karabiner könnte allerdings größer sein. --- ## 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.be/products/393983322-4ft-yellow-scuba-diving-open-bottom-surface-marker-buoy-smb](https://www.desertcart.be/products/393983322-4ft-yellow-scuba-diving-open-bottom-surface-marker-buoy-smb) --- *Product available on Desertcart Belgium* *Store origin: BE* *Last updated: 2026-09-03*
