SMB for Scuba Diving Buyer’s Guide

As an SMB is a safety device, its importance cannot be overstressed. In fact, it is common practice for a diver to carry a second, back-up SMB on their person at all times should he drift off course. These secondary devices can be inflated in the water using exhaled bubbles or by purging your regulator.

Take a look at our buyer’s guide for some tips and features to keep an eye out for when purchasing an SMB.

Visibility

Look for an SMB that features vibrant, bright colors like red, yellow and orange. Other features like flags and reflective material are a great way to stand out. These features will ensure passing vessels can see your SMB in all weather conditions, day or night.

Size

As divers already need to carry an abundance of gear, SMBs are designed to be compact, easily folded or rolled up to fit neatly in your dive bag. Look for an SMB that is roughly 6-7 feet and 4-12 inches in diameter. This will ensure that it remains highly visible when inflated yet stored easily when not in use.

Closed circuit vs. open-ended

SMB’s come available in two options: closed and open-ended.

Open-ended options are easy to inflate in the water. A weight is used to keep the open end slightly submerged, trapping the air inside.

Close-ended SMB’s use a valve to inflate and keep the air in, making them more reliable but unable to inflate under the water’s surface.

Line

The line you will use is determined by where you are launching your SMB. If you’re roughly 5 meters underwater, a short finger spool is a great option. If you are deeper down, consider a long line and a reel mechanism.
