When we first started our scuba diving courses, we were each instructed on the importance of surface marker buoys. We didn’t truly understand their significance until we started diving in highly populated spots. With plenty of boats whipping around while we were underwater, we knew we had to find the best SMB for scuba diving.
Now, when it comes to this type of marker, you can’t really afford to make any mistakes. This is why you should follow our tips and reviews mentioned here. You will find it a great deal easier to select the top make and model for your next dive.
How to Select a Scuba Diving SMB
Here are the top features that you will need to consider when selecting your own SMB:
SMB vs. DSMB
There is often quite a bit of confusion between SMBs and DSMBs. Mostly, divers want to know if they refer to the same safety mechanism or if differences exist between them. Well, for the most part, these two pieces of equipment are rather similar.
As you are aware, an SMB is a surface marker buoy – a DSMB is simply a delayed SMB. As the name suggests, a DSMB is one that is deployed once you are below the surface of the water. With a regular SMB, you first inflate the buoy and then you dive.
So, which one is right for you? In this case, it really is a matter of preference as there is no right or wrong answer. Just remember that if you do select a DSMB, you should choose one made from durable materials. After all, these safety mechanisms have to withstand the obstacles typically associated with ascension.
Open-Ended vs. Close-Ended
Open-ended SMBs are closed on all three sides except the bottommost one. Due to this, it can be filled in a number of different ways. The greatest advantage here is that it allows you to fill the SMB with the help of your alternate airflow line. As a result, you can inflate the SMB easily and quickly.
The close-ended designs are sealed on all sides. The benefit is that absolutely no water can get in. At the same time, it also means that you have to inflate the SMB orally. Therefore, you will need to remove your regulator and blow into the SMB valve. Unless you are a skilled or experienced diver, this may prove daunting for some.
Typically, SMBs are either four feet or six feet long. In most instances, the smaller buoys are more compact when rolled up and are, thus, easier to take with you on your dive. However, there are other factors to consider.
The length that you need will depend on the condition of the diving site. For instance, if the water is relatively calm, then a smaller buoy will still show up against the horizon. If there are more waves, though, you are going to require something taller. This is the only way that your position can be spotted over the waves.
There are now more colors than ever to select from. The most common options are orange, pink, green, and yellow. You can select anything you want as long as the color is bright and can be easily seen, particularly from a distance. So, avoid anything that may seem dull or a little too dark.
It is also a good idea to look for an SMB that has a reflective patch on top. This will make the buoy stand out more, making it easier for others to know where you are. Such a feature can be useful when diving in popular spots.

Depending on the size of the deflated SMB, you can keep it in your suit pocket, hang it from your BCD, or place it on any other ring that can hold it behind you.
Are SMBs Suitable for All Types of Diving?
SMBs can be typically used for all open sea diving sites. They only can’t be used when diving in enclosed areas such as caves.
