What to look for in a SMB


Dive marker buoy reviews will tell you that this is not just a product for beginners. It is an important accessory for every diver. There are many things to consider when looking to purchase a dive marker.


If people are going to be able to see you the dive marker will need to stand out. Most are a bright red or orange color with options for yellow or green. This will notify ships of your location and let them know you are underneath. Fluorescent strips also go a long way to signal your location, especially at night.


Scuba diving requires enough gear as it is. This is why dive markers have been designed to roll into a compact bag. Being able to strap this to your bag will not only make you remember to bring it with you but also not take up crucial space in your pack.

When they are inflated your marker should not be small and compact. Full sized markers will range in size from 4 to 8 feet in length and 4 to 12 inches in diameter. We find that 7 feet is the sweet spot. Anything smaller will be hard to see and anything bigger will add visibility but also bulk to carry.
