One of the most significant innovations in equipment cave divers have seen since the beginning of this century has been the transition from backmounted to sidemount doubles. Many cave divers now sidemount. There may even be more open-circuit sidemount cave divers that backmount cave divers.
To become a technical diver, you need to have passion, experience and training. Technical diving can be dangerous if one or more of these factors is lacking.
Sidemount is a great option for cave diving, as it can offer many benefits to divers. Sidemount was invented by cave divers. These are just a few of the many benefits.
The next day it was on to technical sidemount, which means adding our deco 50-percent oxygen and 100-percent oxygen tanks on either side. This increases your profile underwater so you must keep the tanks as trim as possible against your body. You have a couple of clips on each side of your waist. As you breathe down your tanks and they become positively buoyant, you adjust your tank position to the second clip position. The aim here is to be as streamlined as possible. Every few minutes you also switch your breathing from one tank to the other. That way the pressure in each tank runs down at roughly the same rate, and if there is a failure with either tank or regulator, you’ll still have gas to breathe. As with all new things, building up experience is key to comfort and enjoyment. I spent the next few days doing deco dives with the sidemount rig, buddied up with Evolution co-owner David Joyce — a hugely experienced Tec diver and Trimix instructor. On one dive we visited the Japanese Mogami wreck down at 164 feet, where I was beguiled by the bits of old gas masks, uniforms and even a few bones we saw.
Technical divers search for wrecks and reefs in depths below the recreational limit (40 m/130 ft). These divers have the ability to dive into underwater caves and other areas not accessible by regular recreational diving.
Do you want to become a Sidemount diver. You've come to the right spot, as this article will cover all the details!
You might consider continuing to Tec Sidemount Diver, where you will learn additional skills that are specific to tec diving in sidemount like switching deco cylinders and staging.
However it is important at greater depths to decrease effort and achieve maximum performance to avoid overexertion and CO2 buildup. CO2 is the trigger for our breathing reflex, so the more CO2 we build up the more we will feel the urge to breathe. This means in the same amount of time we will pump more gas through our lungs and we take in more gas in the same amount of time.

Computer-aided instruction forms an integral part of most courses we teach. The Why? The reason is simple. eLearning helps students get in the water earlier and spend more of their time there. We offer all applicable online eLearning programs at no additional charge. They are typically $140. This can translate into an extra day in-water instruction. That is an incredible value. Priceless.
PADI Training is available for both Android(tm), and Apple(r), iOS devices. Devices should not be older than three years old and have the latest OS (operating systems).
Sidemount diving is a great way to get additional air. There are two tanks that you use, one tank with an SPG and the other with regulators. This makes it safer and gives air-hogs like me a lot more air. Sidemount also makes diving extremely easy, since you can simply put tanks on top and there isn't any pressure on your spine.
You can choose from the following options to learn more about diving or for lessons alternatives.
These cards are only issued to those who have earned them. Participating in a course is not a guarantee of certification. Certification cards may be offered by multiple agencies for cave courses. C-cards cost $30 to $30 per card, depending on the agency. Ask your instructor for more information.
- Increased Bottom Time A Closed Circuit diver is not concerned with running out of gas because they are only limited by decompression. This can also be reduced by selecting an oxygen partial pressure that provides the diver with virtually limitless bottom times in 60 feet or less of water.
To begin a technical diving course, you must have completed the following prerequisites: a PADI Advanced Open Water Diver certificate or equivalent, a PADI Enriched Air Diver certificate or equivalent, and a PADI Deep Diver certificate or proof of at least 10 dives to 30 metres/100 feet.
2-3 hours
Even with small cylinders, you can usually dive for 2-3 hours (rebreathers typically have two 2/3l cylinders or one 3/5l cylinder).
