I can easily use it as a finger spool one handed. The Surface Marker Buoy (SMB) is exactly as I hoped for. A large opening on the bottom to fill with an Octo, and a one-way valve in the bottom section doesn't let the air back out, so it will remain inflated at the surface and not lose air if it tips over. Valve to manually inflate by mouth or BCD hose works well. Press in, and inflate by mouth, let go and it springs back and stops air flow, locking it in. Dump valve works, though I haven't tested as a pressure relief yet. I intend to use soon in Hawaii and if I experience any issues, I will revise this review. So far, very pleased with this product and would purchase again. Review: Works well; holds air; tricky to get water out - I used this DSMB on a Caribbean dive trip, for eight dives. Works well and very easy and fast to inflate from octo. Could also be inflated from a LP inflator hose or by mouth. The addition of the relief valve does add bulk when rolled, but make deflating easy. Due to the design of the bottom, it does trap any water that gets inside, but the relief valve can be removed to drain it. The spool and line seem good quality, and the bolt snap is great but a little smaller than I'd prefer (but sized right for the spool). There's a swivel on the end of the line that could be removed if you want a different setup, but it is very nicely spliced and finished off if you choose to keep it. ## Features - HIGH VISIBILITY DESIGN - The Neon red surface marker signal tube is a 5ft surface marker with a Reflective Band tape on both sides for maximum visibility. - EASY FILL & STABILITY - SMB (total weight 390 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 98ft 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 | B092HV3WJC | | Best Sellers Rank | #111,773 in Sports & Outdoors ( See Top 100 in Sports & Outdoors ) #24 in Diving Safety Gear | | Brand | Seafard | | Brand Name | Seafard | | Color | 5ft Red Smb+gray Reel | | Customer Reviews | 4.6 4.6 out of 5 stars (132) | | Date First Available | April 14, 2021 | | Included Components | Clip | | Item Package Dimensions L x W x H | 9 x 5 x 3 inches | | Item Weight | 0.4 Kilograms | | Manufacturer | Seafard | | Material | Aluminum, Nylon | | Model Name | Diving-HY-0801 | | Operation Mode | Manual | | Package Weight | 0.4 Kilograms | | Part Number | 6-2021SSS-5AAA | | Size | 5ft SMB+98ft Reel | | Style | Dving | | Suggested Users | unisex | | Warranty Description | Not Applicale | ## Product Details - **Brand:** Seafard - **Color:** 5ft Red Smb+gray Reel - **Item Weight:** 0.4 Kilograms - **Material:** Aluminum, Nylon - **Style:** Dving ## Images ![5ft Scuba Diving Open Bottom Surface Marker Buoy (SMB) with 98ft Finger Spool Alloy Dive Reel and Double Ended Bolt Clip - Image 1](https://m.media-amazon.com/images/I/71UW1Vfcv6L.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ DSMB - Large bottom Opening with one-way valve to keep air in. *by C***T on October 8, 2025* Finger spool is great size, not too large.
