4. 🌍 Exploring the Underwater World with Tankless Dive Systems

Diver exploring the underwater world with tankless dive system

The Essence of Tankless Diving

More than a new diving method, tankless diving offers a completely unique underwater experience. It’s an ideal choice for various dive destinations, enabling divers to discover the underwater environment without relying on cumbersome scuba tanks. The main benefit of tankless diving is that most of the gear remains on the surface, leading to better mobility, less effort, and minimized water resistance. This results in less underwater noise and disturbance, as the surface air compressor pumps air to the diver through a hose, eliminating the need for heavy tanks.

Tankless diving is generally limited to a maximum depth of 30 feet of seawater (fsw) or 9 meters of seawater (msw). The BLU3 Nomad Dive System allows divers to reach these depths and is powered by a specially designed battery pack nomad.

The BLU3 Difference

Powered by a specially designed lithium-ion battery pack, the BLU3 Nomad Dive System allows divers to descend up to 30 feet underwater. Carrying a few extra packs extends the dive time and allows for more exploration.

5. ⚙️ The Mechanics Behind the Magic: How Tankless Systems Work

Mechanics of tankless dive system with Smart Reg™

Also referred to as Hookah Diving, tankless diving presents a revolutionary alternative to conventional diving systems. Instead of carrying heavy scuba tanks, the diver is connected to a motor/compressor unit on the surface that draws in fresh air and transports it through a hose connected to the diver’s weight belt. This process delivers air efficiently to the diver while reducing the equipment’s weight and making diving more accessible and enjoyable.

A custom battery-powered air compressor, which floats on the water’s surface, supplies divers with an air supply of compressed air via a hose. The pump air is transferred through the intake, down the common hose, then into the individual hoses, and to low pressure regulators, making it easily accessible for the diver’s next breath. A spare battery can be used to prolong the dive time and ensure a seamless diving experience.

Breathing Made Efficient

The heart of BLU3’s Nomad Dive System is the Smart Reg™. This innovative technology offers the following benefits:

  • Monitors the diver’s breathing patterns to efficiently deliver air
  • Ensures a comfortable dive experience
  • Provides a more convenient and enjoyable underwater adventure with Nomad.

The Smart Reg™ offers the following benefits:

  • Uses patented technology to continuously monitor and adjust to the diver’s breathing patterns
  • Conserves battery life
  • Guarantees a consistent and reliable air delivery
  • Ensures the diver gets exactly the right amount of air when they need it

Powering Your Dive

Rechargeable batteries power tankless dive systems, offering a sustainable, eco-friendly substitute for traditional scuba diving. The duration of these batteries varies, with some systems featuring battery packs lasting over an hour and in other cases up to 3 hours.

The type and quality of batteries utilized significantly influence the performance and runtime of tankless diving systems. For instance, while the Sea Lion system is comparable to a gasoline-powered system, the battery-powered Nomad scuba diving system offers approximately 60 minutes of battery time.

6. 🧳 Travel Light and Dive Right: The Portability Advantage

The portability of tankless dive systems stands as one of their most notable advantages. Their lightweight design and convenient transportation options provide a stark contrast to traditional heavy scuba gear, making them an ideal choice for divers who are always on the go.

The Nomad Mini by BLU3 offers the following advantages:

  • Airline-friendly design
  • Capability to explore depths of up to 15 feet with a single battery
  • Compact enough to fit in a backpack, making it easy to take to your favorite dive spots

Nomad’s Flotation Shell Surrounding

Nomad's flotation shell providing buoyancy underwater

Key to the Nomad’s enhanced buoyancy and stability is its flotation shell. Constructed from rotomolded hard, durable plastic filled with foam, the shell ensures Nomad’s unsinkability while diving. This design incorporates additional air volume and buoyant material to counterbalance the weight of the diver and their equipment.

The flotation shell offers several benefits:

  • Ensures the unit’s unsinkability
  • Enhances stability and visibility during diving
  • Provides inherent buoyancy
  • Adds buoyancy through the Dry Bag Float, aiding in maintaining a horizontal position in the water for a smooth and enjoyable diving experience.

On-the-Go Charging

Tankless dive systems offer several advantages:

  • They are portable and easy to carry.
  • They are designed for on-the-go charging, so you can recharge the batteries anywhere.
  • They are always ready for your next underwater adventure, whether you’re on a boat, at the beach, or in your hotel room.

The duration for fully charging a tankless dive system is approximately 3 hours. Moreover, the batteries for tankless dive systems can be easily replaced. For example, the Nemo tankless dive system features a replaceable battery that can be interchanged to prolong dive duration.

7. 🛡️ Safety First: Ensuring Your Own Safety While Tankless Diving

Despite the unique and liberating experience tankless diving provides, safety should always be a priority. As with any form of diving, it is advisable to obtain SCUBA certification to enhance your diving abilities and guarantee safety during tankless diving pursuits.

BLU3 ensures divers are well-equipped to handle their tankless systems with their Online Dive Training Course. The course is designed to equip experienced divers with the necessary knowledge and skills to safely embark on new underwater adventures with Nomad.

  • Waterproof compartments
  • Spare hoses
  • Weight belts
  • Additional gear

These accessories allow divers to customize their equipment to suit their individual preferences and needs.

Accessories like the Dry Bag Float not only offer buoyancy capacity of 44 lbs but also allow for easy inflation by mouth. They also serve as a secure and waterproof storage space for dry items during dives, ensuring that your belongings remain protected and dry while you enjoy your dive experience.

Waterproof Compartment

One such accessory that enhances the tankless diving experience is the waterproof compartment. Available in BLU3’s tankless dive systems, this compartment provides a secure storage space for dry items during dives. Divers can store important items, preventing them from getting wet or damaged while in the water.

The waterproof compartment offers divers peace of mind. They can focus on their underwater exploration without worrying about their belongings getting damaged. It is an example of how tankless systems aren’t just about innovative diving technology; they’re also about providing a convenient, worry-free diving experience.
