• Decompression Diving

Decompression Diving

The SSI Decompression Diving Specialty will teach you how to dive beyond the no-decompression limits. You will learn to plan and conduct dives to a maximum depth of 132 feet with limited decompression using your recreational total diving system and a single decompression cylinder. You will learn and practice how to effectively use your dive computer features, including switching gases, gas integration, time-to-reserve, and time-to-surface. Using these computer functions will become second nature, enabling you to safely conduct dives with limited decompression without hours of dive planning.

Upon completion, you will earn the SSI Decompression Diving Specialty certification and be able to explore stunning deep dive sites or larger wrecks without being restricted by the traditional no-decompression limits. The opportunities to expand your diving adventures have just got bigger!

The goal of this course is to allow you to expand your diving opportunities without having to acquire as much gear as required to earn full Extended Range technical diving certifications. This course is also a great way to find out if you enjoy more technical diving and get comfortable with the team style of diving required of technical divers.

Availability: Contact us for booking information


Knowledge Development

Digital Student Materials - You will read about the theory behind decompression diving and how decompression works in practice, as well as watch videos on the skills we will practice

Classroom Sessions - We will complete a total of 8 hours in the classroom, covering physics, physiology, decompression theory, decompression equipment, and decompression planning. 

Dry Land Session - We will work with your dive equipment to ensure it is appropriately set up for decompression diving procedures. 


Pool Session

During our pool session, we will work on managing the extra tank you will carry, as well as how to effectively switch from your back gas to your decompression gas. You will also practice emergency procedures and running simulated decompression while assisting a teammate. 


Ocean Sessions

We will complete three dives. During our first dive, we will conduct simulated decompression. On the following two dives, we will conduct decompression dives, while practicing appropriate team procedures and exploring underwater!



You must be 18 years old or older to participate in this program. 

You must be certified, from a RSTC recognized training agency, with the following certifications:

Additionally, you must have at least 50 dives. We conduct all of the above courses throughout the year and have a package for this program.


We also strongly recommend all divers have excellent buoyancy control (you should be able to maintain a hover at a fixed depth for 5 minutes without more than a 1 foot deviation. If you want to work more on your buoyancy skills, please consider the Perfect Buoyancy course. Inability to maintain stop depth is the most common reason divers are unable to progress towards decompression certifications, so strongly recommend this program to everyone who wants to move forward with decompression diving. 


If you have any questions about prerequisites, please contact us at training@beyondlandadventures.com


Required Gear

Decompression diving requires us to solve problems while at depth, so our gear must be in great contiions, properly serviced, and we will carry redundancy for many gear items. If you are unsure if your gear meets the requirements of this program, please come see us. There are no exceptions made to the gear requirements. If you do not have the required gear prior to dry land session, you will be removed from the course without any refund. Please come talk to us so we can make sure you have gear you can rely on!
