Technical Diving Equipment: A Definitive Guide


Want to know what technical diving really means? Right from a tech dive computer, dive system tech fins and harness systems to multiple gas cylinders and dive lights. Equip yourself with the tools needed to explore uncharted environments and more. Redundant life support systems and drysuits provide added safety and thermal insulation, while reel and line systems assist with navigation.

Buy high-quality technical diving gear and undergo solid training to ensure a successful and safe dive. Travel deep into the ocean with confidence, knowing you have the right equipment to fully experience the thrilling underwater world.

Tech diving involves diving beyond the normal limits of recreational scuba diving. Indulging in tech diving requires extra experience, training and equipment. The equipment used by technical divers differs considerably from that used by recreational scuba divers. Even when it appears similar, the technical diver will usually either carry more equipment or configure it slightly differently.

So, invest in technical diving gear and get ready to conquer the underwater world. Remember, the right technical diving equipment is your ticket to diving with confidence and enjoying the incredible world of technical diving to the fullest.

First Things First: A Technical Dive Computer

A dive computer is a critical piece of equipment for technical divers. Unlike recreational divers who rely on dive tables, technical divers require real-time information about their depth, bottom time, and decompression obligations. Dive computers track these parameters, calculate safe ascent profiles, and provide vital data to manage gas mixtures and decompression stops accurately. It is crucial to choose a tech dive computer that supports multiple gas mixes and offers accurate decompression calculations.

Support It Is: Harness and Backplate

Unlike recreational divers who typically use jacket-style buoyancy control devices (BCDs), technical divers often prefer a harness and backplate system in their tech dive gear. This setup provides better stability, streamlining, and control in the water. The harness ensures a snug and secure fit, while the backplate distributes the weight of the diving equipment evenly across the diver’s back, enhancing comfort and maneuverability during dives. This configuration allows technical divers to carry multiple gas cylinders, additional equipment, and accessories necessary for their dives.

Breathe Well: Multiple Gas Cylinders

Technical divers rely on multiple gas cylinders to manage different gas mixtures required for varying depths and decompression stops in their technical diving gear. These cylinders are usually connected through a manifold system, allowing divers to switch between gas sources seamlessly. Proper gas management and switching procedures are crucial skills that technical divers must master to ensure a safe and successful dive.

The Reel Life: Reel and Line

Technical divers often explore complex underwater environments such as caves and wrecks. In these challenging conditions, a reel and line system is an essential tool in the technical diving equipment. The reel contains a length of line that the diver can unwind as they explore, marking their path and ensuring a safe exit. Proper training in the use of the reel and line system is essential for technical divers to ensure effective navigation and safe exploration.

The Non-Negotiable: Redundant Life Support Systems


Technical diving pushes the boundaries beyond recreational limits, resulting in higher risks. To address these risks, technical divers utilize redundant life support systems, which consist of duplicate regulators, dive computers, buoyancy control devices, and essential technical diving equipment. The purpose of redundancy is to ensure that if any component fails or malfunctions, divers have an alternative system at their disposal.

It’s Not All Wet: Drysuits

As technical dives often involve diving in cold water or for extended durations, drysuits are commonly used to provide thermal insulation. Unlike wetsuits, which allow water to seep in and then insulate the body, drysuits keep the diver dry by sealing the body off from the surrounding water. By wearing appropriate thermal undergarments, divers can stay warm and comfortable during prolonged dives. Drysuits are especially crucial in technical diving, where divers may be exposed to low temperatures and extended decompression obligations.

More Than Regular Fins: Tech Diving Fins

Tech diving fins are designed for advanced divers exploring deep and challenging environments. These fins offer excellent propulsion, maneuverability, and stability underwater. They are typically longer, stiffer, and feature specialized designs to optimize efficiency and power. Tech diving fins provide the necessary thrust for divers to navigate currents and explore complex dive sites.

Vision Express: Dive Lights

Technical dives often take divers into dark and visually challenging environments. Dive lights are essential tools for illuminating the underwater world, providing better visibility and allowing divers to navigate effectively. Depending on the dive conditions, technical divers may use primary lights, backup lights, and even handheld lights for added convenience. Proper lighting is crucial for maintaining situational awareness, reading dive instruments, and exploring the intricacies of underwater structures.

Technical diving requires specialized equipment to safely explore the depths and overcome the challenges presented by extended dive times, challenging environments, and increased risks. By investing in high-quality technical diving equipment and undergoing proper training, technical divers can enjoy the thrilling dives that are more than just regular ones!
