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: Muy bien - La boya es buenísima. Funciona perfecto. El carrete es más pequeño de lo que me hubiera gustado y el cordel utilizado no me gusto (por ser plano y se riza con extrema facilidad) ## Features - HIGH-VISIBILITY SURFACE MARKER — 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 — 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 — 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 — 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 — 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 | #151,466 in Sports, Fitness & Outdoors ( See Top 100 in Sports, Fitness & Outdoors ) #24 in Diving & Snorkelling Safety Gear | | Brand | Seafard | | Brand Name | Seafard | | Colour | 4ft Red Smb+gray Reel | | Customer Reviews | 4.4 out of 5 stars 240 Reviews | | Item Diameter | 7 Inches | | Item Dimensions | 120 x 15 x 2 Centimeters | | Item Weight | 0.8 Pounds | | Item dimensions L x W x H | 120 x 15 x 2 Centimeters | | Manufacturer | Seafard | | Manufacturer Part Number | dsfsdgfsg-001 | | Material | Aluminum Stainless Steel Nylon | | Material Type | Aluminum Stainless Steel Nylon | | Model Number | dsfsdgfsg-001 | | Number of Items | 1 | | Number of Packs | 1 | | Operation Mode | Manual | | Style | diving | | Style Name | diving | | UPC | 725691765471 | | Unit Count | 1.0 Count | ## Product Details - **Brand:** Seafard - **Material:** Aluminum+Nylon - **Colour:** 4ft Red Smb+gray Reel - **Item dimensions L x W x H:** 120 x 15 x 2 Centimeters - **Style:** diving ## Images ![4ft Red Scuba Diving Open Bottom Surface Marker Buoy (SMB) with 49ft Finger Spool Alloy Dive Reel and Double Ended Bolt Clip - Image 1](https://m.media-amazon.com/images/I/61e5i0rwuXL.jpg) ![4ft Red Scuba Diving Open Bottom Surface Marker Buoy (SMB) with 49ft Finger Spool Alloy Dive Reel and Double Ended Bolt Clip - Image 2](https://m.media-amazon.com/images/I/71-00u2rhkL.jpg) ![4ft Red Scuba Diving Open Bottom Surface Marker Buoy (SMB) with 49ft Finger Spool Alloy Dive Reel and Double Ended Bolt Clip - Image 3](https://m.media-amazon.com/images/I/61mruwn4W2L.jpg) ![4ft Red Scuba Diving Open Bottom Surface Marker Buoy (SMB) with 49ft Finger Spool Alloy Dive Reel and Double Ended Bolt Clip - Image 4](https://m.media-amazon.com/images/I/61qW+OhGtxL.jpg) ![4ft Red Scuba Diving Open Bottom Surface Marker Buoy (SMB) with 49ft Finger Spool Alloy Dive Reel and Double Ended Bolt Clip - Image 5](https://m.media-amazon.com/images/I/61i9VslF8uL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Nice, well constructed DSMB *by M***K on 19 October 2020* Very decent DSMB Pros: multiple ways to inflate (mouth, inflator hose, regulator).
