Reflective tape on top. Heavy duty material and construction. Aluminum finger spool. Stainless swivel. Purge valve. 60ft of line. Stanless d ring attachment. Velcro and bungee keeps it securely rolled up. Cons: spool is small for 60ft of line making it difficult to get clip through holes (I cut 10ft off which helped resolve the issue). Loop to attach to smb d ring is on the small side but workable. A bit on the bulky side. Takes a number of breaths to inflate (easier to do with regulator). Overall very satisfied with this DSMB for the price point. Review: Very good DSMB - I am happy with this DSMB. It has already been on one dive with me, and it held up well. I do wish the spool was a bit bigger - it works well for me. ## Features - HIGH-VISIBILITY SURFACE MARKER β€” 4FT red SMB with reflective bands on both sides helps create a more visible surface signal for scuba diving, snorkeling, and other underwater activities. - OPEN-BOTTOM INFLATION β€” Open-bottom design supports inflation with a regulator or oral inflator, making the SMB easier to deploy underwater when a quick surface marker is needed. - DURABLE 210D NYLON + TPU β€” 210D nylon fabric with TPU coating provides a durable construction, while the built-in overpressure relief valve helps release excess air during ascent. - 49FT ALUMINUM FINGER SPOOL β€” Corrosion-resistant aluminum alloy dive reel with 49FT braided nylon line and 316 stainless steel double-ended bolt snap for controlled line handling. - COMPACT SMB DIVE KIT β€” 4FT surface marker buoy and 49FT dive reel combine into a compact setup for scuba, wreck diving, cave diving, snorkeling, spearfishing, and underwater photography. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07TX99GTP | | Best Sellers Rank | #145,600 in Sports & Outdoors ( See Top 100 in Sports & Outdoors ) #34 in Diving Safety Gear | | Brand | Seafard | | Brand Name | Seafard | | Color | 4ft Red Smb+gray Reel | | Customer Reviews | 4.4 out of 5 stars 342 Reviews | | Item Diameter | 7 inches | | Item Dimensions | 47.24 x 5.91 x 0.79 inches | | Item Highlight | High-Vis 4FT SMB with Reflective Bands, Open-Bottom Inflation, 49FT Aluminum Finger Spool and 316 Stainless Steel Bolt Snap | | Item Type Name | Surface Marker Buoy | | Item Weight | 12.8 ounces | | Item dimensions L x W x H | 47.24 x 5.91 x 0.79 inches | | Manufacturer | Seafard | | Manufacturer Part Number | dsfsdgfsg-001 | | Material | Aluminum, Nylon, Stainless Steel | | Material Type | Aluminum, Nylon, Stainless Steel | | Model Number | dsfsdgfsg-001 | | Number of Items | 1 | | Number of Packs | 1 | | Operation Mode | Manual | | Style | diving | | Style Name | diving | | UPC | 725691765471 | | Unit Count | 1 Count | ## Product Details - **Brand:** Seafard - **Material:** Aluminum, Nylon - **Color:** 4ft Red Smb+blue Reel - **Style:** diving - **Operation Mode:** Manual ## Images ![4FT Scuba Diving SMB, Open Bottom Surface Marker Buoy +49FT Gray Dive Reel - Image 1](https://m.media-amazon.com/images/I/61e5i0rwuXL.jpg) ![4FT Scuba Diving SMB, Open Bottom Surface Marker Buoy +49FT Gray Dive Reel - Image 2](https://m.media-amazon.com/images/I/71-00u2rhkL.jpg) ![4FT Scuba Diving SMB, Open Bottom Surface Marker Buoy +49FT Gray Dive Reel - Image 3](https://m.media-amazon.com/images/I/61mruwn4W2L.jpg) ![4FT Scuba Diving SMB, Open Bottom Surface Marker Buoy +49FT Gray Dive Reel - Image 4](https://m.media-amazon.com/images/I/61qW+OhGtxL.jpg) ![4FT Scuba Diving SMB, Open Bottom Surface Marker Buoy +49FT Gray Dive Reel - Image 5](https://m.media-amazon.com/images/I/61i9VslF8uL.jpg) ## Available Options This product comes in different **Color** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Nice, well constructed DSMB *by M***K on October 19, 2020* Very decent DSMB Pros: multiple ways to inflate (mouth, inflator hose, regulator).

It has already been on one dive with me, and it held up well. I do wish the spool was a bit bigger - it works well for me. ### ⭐⭐⭐⭐ Good value SMB and spool *by A***. on August 5, 2021* I haven't shot the SMB in the water yet, but it appears to be well made. It has double seams along the sides, which is nice. The ones with single seams can sometimes wear along the non-stitched side. It can be orally inflated (or with the LP hose) or via the octo purged into the open bottom. It is self-sealing, which is a nice feature and will keep it from flopping over and deflating on the surface. However, I suspect that exhaust from the primary will not provide enough pressure to inflate it that way; probably have to use the octo. I might be wrong, however, so I'll have to try in the water. The spool is pretty good. It has a nice, large hole so it's suitable for cold water diving with gloves on. I like that it's aluminum. Like pretty much every finger spool, you'll have to strip off some line in order to expose enough of the holes so you cal clip off a bolt snap. I stripped off about 15' and it's fine now. That leaves about 30' of line on the spool, which is good for shooting the SMB from a safety stop in most situations. If you need to shoot it from deeper or while in a strong current, this might not be enough line. The swivel and leader is a nice touch. Unfortunately, the leader is too small to be useful. The diameter of the loop is not large enough to easily slip over the spool when clove-hitching the SMB to it. It can be done, but not easily, which means it will be even more difficult in the water (and probably impossible with gloves on). I removed it and used some of the stripped line to tie a larger loop. Now it's perfect. Overall, if you are looking for a good price on a small SMB and spool, this fits the bill. Perfect for most calm-water situations when you are shooting an SMB from your safety stop. If you dive when the swell is high or when the current is ripping or need to release an SMB from much deeper, then you probably want a larger SMB and a larger spool. --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.no/products/150934394-4ft-scuba-diving-smb-open-bottom-surface-marker-buoy-49ft](https://www.desertcart.no/products/150934394-4ft-scuba-diving-smb-open-bottom-surface-marker-buoy-49ft) --- *Product available on Desertcart Norway* *Store origin: NO* *Last updated: 2026-09-18*
