Was great until I dropped it and it unspooled all the way to the bottom and got wedged between rocks. I had to cut it and leave. Wish it attached and could retract. I kept getting it wrapped in my flippers when I surfaced Review: Really good buoy but! The line is really short , as it is described yes i know but just keep in mind this is to short for any 10m below dives, for a safe and confortable deployment. ## Features - HIGH VISIBILITY DESIGN - The Neon yellow surface marker signal tube is a 4ft surface marker with a Reflective Band tape on both sides for maximum visibility. - EASY FILL & STABILITY - SMB (total weight 360 grams) can be filled using the oral inflator, or through the use of a regulator in the open bottom of the SMB. - RUPTURE RESISTANT - Made from a 210D Nylon Fabric with a TPU coating for added strength in all water conditions and a built-in over pressure relief valve allows the tube to ascend without rupturing. - SMB FINGER SPOOL - Strong and corrosion resistant aluminum metal finger spool dive reel with 49ft of braided nylon line and stainless steel double ended bolt clip. - LIGHTWEIGHT & COMPACT - The combination ideal for cave and wreck diving, scuba diving, travelling diver, snorkeling, photography and other underwater activities. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B08LZ3LZ44 | | ASIN | B08LZ3LZ44 | | Best Sellers Rank | #12,489 in Sporting Goods ( See Top 100 in Sporting Goods ) #7 in Diving Reels | | Brand Name | Seafard | | Color | 4ft Yellow Smb+blue Reel | | Customer Reviews | 4.3 4.3 out of 5 stars (54) | | Customer reviews | 4.3 4.3 out of 5 stars (54) | | Date First Available | 1 January 2024 | | Department | Unisex | | Installation Method | built-in | | Item Dimensions | 121.9 x 15 x 2.5 centimeters | | Item Type Name | Surface Marker Buoy | | Item Weight | 136 g | | Item model number | HY-00120278US | | Manufacturer | Seafard | | Manufacturer | Seafard | | Material Type | Nylon | | Model Number | HY-00120278US | | Operation Mode | Manual | | Product Dimensions | 121.92 x 14.99 x 2.54 cm; 136.08 g | | Style Name | DIVING | ## Product Details - **Brand:** Seafard - **Colour:** 4ft Yellow Smb+blue Reel - **Item dimensions L x W x H:** 121.9 x 15 x 2.5 centimeters - **Material:** Nylon - **Style:** DIVING ## Images ![4ft Yellow Scuba Diving Open Bottom Surface Marker Buoy (SMB) with 49ft Finger Spool Alloy Dive Reel and Double Ended Bolt Clip - Blue - Image 1](https://m.media-amazon.com/images/I/61WbluvVD3L.jpg) ## Available Options This product comes in different **Color** options. ## Customer Reviews ### ⭐⭐⭐ Review *by A***A on 16 December 2021* Used this snorkeling. Solo trip. Was great until I dropped it and it unspooled all the way to the bottom and got wedged between rocks. I had to cut it and leave. Wish it attached and could retract. I kept getting it wrapped in my flippers when I surfaced ### ⭐⭐⭐⭐ Review *by L***E on 17 December 2024* Really good buoy but! The line is really short , as it is described yes i know but just keep in mind this is to short for any 10m below dives, for a safe and confortable deployment. ### ⭐⭐ Review *by R***Y on 21 July 2024* The reel is very small. Made for a child's hands and the line is very thin. Says it included a double ended clip, but I didn't receive one. Now I have to go buy that separately. I at least hope the smb holds air. I like the colour so i gave it 2 stars instead on 1. I would return, but I'm off to the carribean in days and don't have time to order a different one. --- ## 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.tn/products/393983322-4ft-yellow-scuba-diving-open-bottom-surface-marker-buoy-smb](https://www.desertcart.tn/products/393983322-4ft-yellow-scuba-diving-open-bottom-surface-marker-buoy-smb) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-06-03*
