Swim buoy for snorkeling – Why and how to use a dive flag?

Swim buoy for snorkeling is an accessory that helps to be visible in areas where there is intense boat traffic or while swimming in open water. Using a high visibility floating surface marker is essential for your own safety by clearly indicating the wearer’s position and helping to rest if needed. This post explains what type of dive buoys are available and which one is the best for snorkelers!

What is a swim buoy?

A swimming buoy is an inflatable accessory that serves as a dive flag by letting people know that someone is in the water, provides a resting platform if needed and can work as a buoyancy aid too. Due to its bright color, it increases the user’s safety (a black swimming or snorkeling suit is almost invisible in open water to boaters) but doesn’t replace a personal flotation device or a snorkel vest.

Why use a dive flag for snorkeling?

Using a highly visible flag is a common practice in diving, but swimmers and snorkelers rarely carrying any surface marker. Most beach holiday destinations have laws regarding using one and there are various safety and practical reasons too why you should get one.

Benefits of using a snorkeling flag:

  • makes the user noticeable to boats, surfers, jet-skis and other swimmers so helps to avoid accidents
  • helps the family (or coach if you do some training) to track the wearer from the shore
  • serves as a buoyancy aid and provides a small resting platform when the swimmer gets tired
  • models with dry compartment can store phone, ID, keys, etc…

Surface marker buoy types

There are various marker buoys available that all have their advantages and disadvantages. Here we list the most common models and explain which one works the best for snorkeling.

Snorkel buoy

A snorkelbuoy is a small floaty that is attachable to the snorkel tube and works as a surface marker. It makes you noticeable, moreover, it also prevents your mask from sinking to the bottom of the sea in case you accidentally drop it.

Swim buoy

This is a floating accessory that is highly visible, easy to inflate/deflate, compact, lightweight and attachable to the waist but to your surfboard or kayak too. Due to its small size and wide usability, we recommend choosing a swim buoy for snorkeling, open water swimming and any other water sport.

Dive float with flag

A classical surface marker buoy in red or orange color with a red-white dive flag on it. Using a dive float and dive torpedo is a must in many countries when divers are in the water and they are available in most water sport stores.

Torpedo buoy with dive flag

Diving floats are designed to be carried on a long line that makes them easy-to-fix to underwater objects such as wrecks, but for snorkelers, it can be inconvenient to carry a dive buoy because they are large and don’t have such practical attachment options like a snorkeling dive flag has. The long line can be dangerous while surface swimming since it can get caught in your fins, on corals or in worse cases, in a boat motor. For snorkeling, choose a swim buoy that you can attach at your waist instead.

Safety sausage

A dive sausage is a long inflatable tube in red or orange color. These accessories are used mainly by divers but can be carried on the surface too, however it is not the most ideal way of letting boats know where you are if you are snorkeling.

snorkeling buoy recommendation

To keep yourself visible, you should hold it in upright position, which is of course not possible all the time while observing corals and fish. If you just let it float on the water, it won’t get attention since it is quite flat. We don’t really recommend this as a snorkeling dive flag, better choosing a swim buoy instead!

How to use it a swim buoy for snorkeling?

Snorkeling safety markers are easy-to-use and follow the user almost unnoticeable.

Setting up a swim buoy takes just a few easy steps:

  • inflate it fully
  • fix the belt to your waist
  • attach to tether to the buoy
  • set up the correct length
  • you are ready to go

Don’t attach to yourself an inflatable buoy if you are freediving while snorkeling since it will restrict your movements, moreover the line can get caught in your legs or other objects around you. In this case, one person in your group (your buddy if there are just the two of you) who is not freediving should carry the marker and when the other one swims down, you should stay close to each other.

When not in use, rinse the buy with freshwater, dry it fully and deflate it so you can store it in your snorkeling bag or sport accessory box.
