A scuba marker buoy is a key piece of gear that will ensure your safety when under water. If you are diving in water which is being used by a lot of people, then it is imperative that the people on the surface know you are underwater. Hazards, such as boats passing overhead when you are surfacing, or divers diving in the same area, exist, and you should always have a safety-first mental when you are under the water.
The best surface marker buoy will not weigh you down or inhibit your dive at all, but it will allow you to communicate where you are in the water. These dive markers give your party an idea of where to pick you up and how far you have drifted. The top-rated SMBs are easy to use and will inflate in seconds, allowing you to be safe, but also to enjoy your dive.
It is important to find the best diving SMB so that you can properly enjoy your dive. The SMBs on our list will keep you safe when you are in the water. Here are our top 10 for 2018.
How To Choose A SMB For Scuba Diving – Buying Guide
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.
Closed-Circuit vs. Open-End SMBs
When you are looking at an SMB, you will notice that you have two options: closed and open-end. The two options are what you would expect from the name. The open-end SMBs have an open end. This makes them easier to inflate. The open end will have a weight to keep the open end under the water. If the end does breach the surface of the water, then the air will escape, but they are easier to use and inflate. They are also easier to deploy at depth, but may not be as visible when you do. Closed-end SMBs have a valve to keep the air in. Once they are inflated, they are easier to keep inflated.
One thing we like about the open-end SMBs is that they are easy to inflate. You can use any source of inflation to put air into it, but one handy way to inflate them is to do so with your exhalation bubbles when you are in the water. You can exhale your bubbles directly into the dive marker and inflate it without another inflation device.
For the closed SMB, you need to blow into the valve to inflate it. This generally involves taking in a breath through your regulator, taking the regulator out of your mouth, and then exhaling into the marker. They are trickier to inflate, especially at depth but will stay inflated when you have them inflated.
You will find that SMBs will come in a variety of bright colors, with the main two colors being yellow and orange. The color should not be much of a choice when it comes to the actual color, but you should ensure that your dive marker can be seen. You would not want to use a dark colored marker in the ocean, and you would probably not want to use a bright blue marker in tropical waters. Sticking with yellow or orange is a safe choice for being spotted at distances.
The line you need will depend on where you are launching your marker from. If you are five meters down and are launching your marker, then you would not want a long line, and a finger spool would be an adequate way to launch your marker. If you are down deep, then you will want a longer line and a better way to dispense the line. You may want to use a reel at depth. The other option is to use a weighted line. You drop the weight to unfurl the line, inflate the marker, and then launch the SMB.
Depending on the currents and type of water you are diving in, you may want a line which is attached. If you use a finger spool or a reel, then you can follow the SMB as it goes to the surface. The other benefit of having a line attached to the SMB is that you or the SMB will not drift from each other. When the boat comes to the marker, the attachment will ensure that you are below the marker and have not drifted off.
Q: What Is A SMB?
A: An SMB is a surface marker buoy. An SMB is a piece of safety equipment for when you are diving. When you are under the water, you can launch an SMB to indicate your location or as part of a safety check. Your mask and your scuba equipment will help to keep you safe when you are diving, but another important safety precaution is to have an SMB with you. When you launch it, it helps to show other divers and boats where you are. It allows you to go deeper into the water without worrying about becoming separated from your dive boat.
When you get to a point in the water where you need to perform a safety check, or if you want to place a marker so that people know your position, then you can launch your SMB. TO do this, you open your SMB and inflate it. You may have an inflation device which you can attach to it, or you could inflate it with your exhalations. This can be done in one of two ways. If you have an open end, then you can allow your air bubbles to be caught in the device. If there is a valve, then you will have to exhale directly into the device. Once you have filled the device, you can let it go, and it will float to the surface of the water.
Q: Why Do I Need A SMB?
A: There are even some destinations where an SMB is mandatory for a diver. One of the biggest advantages that an SMB provides is not having other boats sailing over your position when you are coming back up to the surface. It can be dangerous to be completing your ascent when a boat sails straight through your position. An SMB will prevent that from happening.
SMBs are a great way to communicate your position to other divers and boats. They allow you to be rescued easier if you get into trouble and they keep danger from getting in your way.
Q: Open At The Bottom Or Self-Sealing SMB?
A: The choice is entirely up to you. The open-bottom SMBs are easier to inflate, and you do not need to take your regulator out of your mouth to fill them. You will need to do a little more work with a closed-end SMB, but once they are inflated, they will stay inflated, and be easier to use.
