How much weight does a scuba diver need?

How much weight should I need for scuba diving? This can be considered one of the most common questions asked by scuba divers. As a scuba diver, you need to be equipped with the right weight in order to have the best diving experience.

Plenty of methods are available for the scuba divers to determine how much weight they need. However, it is important to figure out how you can keep away from being significantly over-weighted or under-weighted, as both of these problems can cause a diver to use waste energy in order to maintain neutral buoyancy.

Here are few steps that you can follow in order to figure out the ideal weight to enjoy your scuba diving experience.


First, don’t forget that the scuba tank you use for scuba diving has its weight as well. If you do the weight check with a filled tank, you will end up being underweighted. Therefore, you should make sure that your tank is close to empty when you are conducting the test. Good time to do it is end of the dive while you float at the surface waiting for the boat to pick you up. Very convenient option aswell is to do it in a training pool before you go diving into the open water. Remember the pool contains less dense freshwater and you will have to compensate for it before you go to the salt water. General rool is 15 % extra weight on your wieght belt or in weight pockets. If you are using a drysuit, you should make sure that there is little air in it as well. On the other hand, if you are diving with a wetsuit, you should ensure that it is really wet. Otherwise, tiny air bubbles would get trapped when you descend and this can create an impact on your buoyancy.

Next, you should get into the water that is over your head and dump all of the air from your BCD. After that, you will have to take a normal breath, hold it and stay still. While holding your breath, you need to notice where you float in water. If you are properly weighted you should float at eye level. If you cannot get onto the top of the water, you need to remove some weight and try again as you are over-weighted. On the other hand, if your head pops out of the water above the level of your eyes, you should increase your weight as you are under-weighted. This method will assist you to figure out if you are properly weighted so you can enjoy your diving experience.

Now you have a clear understanding about how to calculate the ideal weight that you need for scuba diving. If you are a person who dives frequently, it is important to get your weight checked at least from time to time. Or, if you go less frequently, you can think of checking the weight before you go on your scuba diving vacation.

It is also important to keep in mind that the changes that take place in your body fat percentage can also create an impact on your buoyancy. Another factor to consider is keeping an eye on the wear and tear of your scuba diving equipment. When you change your scuba diving equipment, it is important to do a weight check again. Pay particular attention when wearing a new or different wetsuit. Factors that can affect your buoyancy include the thickness of the wetsuit, as well as the style i.e. shorty or full. These factors can create an impact on your entire scuba diving experience and you need to be aware of them.
