If you think about it, breathing underwater is pretty remarkable, and it all happens because of the regulator. The scuba regulator is a great invention that delivers the air from your scuba tank to you just the way you need it to breathe. More...
Scuba diving with a sidemount configuration simply means that you carry your tanks at your sides instead of on your back. This can reduce drag and is more comfortable for many divers. Sidemount divers often dive with two smaller tanks that are attached in the water. This makes carrying tanks and kitting up easier, especially for those who have difficulty lifting or walking with a backmounted tank. Technical divers typically need to carry extra cylinders, and believe that using a sidemount setup is the best option.
The PADI Sidemount Diver course introduces divers to sidemount techniques for recreational scuba diving. The Tec Sidemount Diver course teaches technical divers how to mount at least four tanks for their technical diving adventures.

Standard Sidemount Features
- BCDs (buoyancy control devices) used for sidemount are usually wing style with a harness and different tank attachment points than backmount BCDs.
- Tanks attach at the hip and on the upper chest, at armpit level on either side.
- Most configurations use an elastic system (bungee, tubing, etc.) to hold tanks in place, or clips that attach to chest D-rings.
- One or two regulators with SPGs (submersible pressure gauges) to match the tanks, and at least one must have a low pressure inflator hose that hooks into your BCD.
Optional and Desirable Sidemount Features
- Many harnesses are padded for comfort and have pockets for weights to balance your trim. Most have crotch straps to keep the harness properly positioned.
- Some harness and BCD designs allow you to change out parts, allowing you to use the system for either backmount or sidemount diving.
- For cave diving, some BCDs have hoses that attach near the bottom of the bladder instead of the top.
- Cylinder-mounted weights allow you to fine-tune weight position during the dive by loosening and sliding the band up or down the tank.
How to Choose Your Sidemount Gear
There are many sidemount diving systems available and your PADI Sidemount Instructor or Tec Sidemount Instructor can give you with the best advice regarding which sidemount rig will work for you. Here are a few considerations:
- Where you dive and what kind of tanks you use affect how much lift you need from your BCD.
- You need to be able to easily and comfortably handle all clips and attachments. If you’ll wear thick gloves while sidemount diving, it’s a good idea to try putting on and taking off tanks with your gloves on. If you plan to boat dive with your sidemount system, make sure you’ll be able to quickly secure and release tanks on a moving platform or in choppy conditions.
Take Care of Your Sidemount Gear
To keep your sidemount equipment in good shape, follow the three general maintenance procedures:
- Rinse thoroughly with fresh water after each use – both the outside and inside or your BCD.
- Let it dry completely – out of direct sunlight as much as possible.
- Partially inflate the BCD and store in a cool and dry place. Don’t leave weights in the harness weight pockets.
