Dive Alert Surface Marking Buoy - Orange
- Inflate the SMB on the surface OR at depth
- {65 in | 165 cm} long by {8 in | 20.3 cm} wide

- Baffle prevents air from releasing at the surface
- Top strap provides an attachment point for a strobe
The value priced Dive Alert™ Orange SMB is inflated with your second stage regulator. It has a one-way duckbill baffle closed base, which prevents air from releasing at the surface. You may inflate the SMB on the surface OR at depth because an over-pressure valve (OPV) prevents over-inflation but also allows for rapid deflation when required. The nylon strap at the top provides an attachment point for a light or slate and two strips of reflective tape across the top significantly increases visibility.
The SMB is {65 in | 165 cm} long by {8 in | 20.3 cm} wide and although it should not be used as a lift bag it has approximately {40 lbs | 18.1 kgs} of buoyancy. Constructed of durable 400 denier polyurethane coated nylon material in high visibility orange color on both sides and includes two velcro straps to retain a tidy compact roll for storage.

Great surface marking boy
on 15 May, 2018
I don’t usually use a service marker here in California either off the beach or in the kelp beds at the Channel Islands. But I did take this out on a beach dive and used it from 20 feet. I added a s/s snap link to it so that I could clip it to my plate. I found by loosening the Velcro strap I could easily unroll and fill it with ease and let it deployed to the surface. I tried this six times and never had one problem with it, I’m really glad that it’s longer than 3 feet like so many I see. I’m leaving at the end of this month for a month in the Philippines and will be diving in areas known for their strong currents. I’m looking forward to having a surface marker buoy that sticks out of the water higher and is also a little wider than most others I would highly recommend this marker to other divers .Comment Thank you for your feedback!

A better SMB from Dive Alert: looking forward to using it
on 17 February, 2018
We saw this SMB from Dive Alert being used on a recent dive trip (by the crew of the Nautilus Belle Amie) and decided to replace our current ones with this one. I like the opening where the regulator is placed, the length, and the sleeker design. I look forward to the peace of mind I'll have by having this with me on future trips.Comment Thank you for your feedback! You already voted Sorry, we failed to record your vote. Please try again -
Very visible surface marker
on 26 December, 2017
Although a bit larger than I wanted, this SMB rolls up tight and fits nicely in my pocket. When inflated properly it is remarkably visible from boat traffic and mostly from the captain of your boat! Heavily built and strongly stitched . Unlike other smb’s this one has a convenient handle on top that makes it easy for the crew to grab and swing back in the boat. If you need to be seen on the ocean, this is the one. As always, wash it after each dive.Comment Thank you for your feedback! You already voted Sorry, we failed to record your vote.
