We are selling a cold-water-capable regulator set " Aqualung Legend" "ready for dive" from our freshwater project.

The Legend model has the same features and performance as the Legend LUX and Legend LX models, with one notable exception: instead of the MBS double control valve, the Legend model is equipped with a Venturi switch.

First stage:

Automatic Closure Device (ACD) – prevents the ingress of corrosive water into the first stage inlet by automatically closing as soon as the Legend is removed from the cylinder valve.
This prevents the internal lubricant from being washed out.
Safer at elevated oxygen levels
The unique, pressure-balanced membrane design ensures superior performance at depth.
Two HP ports and four MP ports are angled to ensure optimal hose routing.
An environmentally friendly drying system keeps water out of the main spring chamber, thus preventing ice formation and keeping out mud and contaminants.
Compatible with up to 40% O₂ immediately after unpacking.

Second stage:

The pneumatically balanced second stage ensures gentle, easy breathing.
A Venturi switch prevents free flow at the surface and when the regulator is not in the diver's mouth.
The opening resistance is fixed and preset, so the diver doesn't have to worry about adjusting the regulator during the dive.
The Comfo-Bite mouthpiece virtually prevents any jaw fatigue.
A (patented) heat exchanger surrounding the valve mechanism dissipates the cold generated by gas expansion and simultaneously absorbs heat from the surrounding water.
The ergonomic exhalation T-piece directs exhaled bubbles out of your field of vision. The design also contributes to less effort when exhaling.

I am selling my Uwatec dive computer, including transmitter, which has seen very little use overall.

The computer can take air and nitrox breathing gases (up to 99% O2) into account for its calculations. Multiple transmitters can be paired, and gas switching can be performed underwater. The display can be actively backlit.

The battery is unfortunately dead, but can be replaced at any time by a specialist retailer. The battery type (CR2450) in the transmitter can be replaced by the user.

The transmitter is also compatible with other TCs from Uwatec (Galileo, Luna).

Also included is the case in which the TC can be safely transported.

Asking price 300 EUR (negotiable) minus the cost of a new battery (200 EUR negotiable).

Please feel free to contact us if you have any further questions.

VG, Mario

With the Suex from the XK1 series, a "Rock solid" exploration scooter is for sale here. With the year of purchase 2014 , he already has veteran status, but pulls the diving team consistently as on the first day.

It is equipped with brand-specific solid control technology. The speed control is infinitely variable via the rotary switch on the body. The charge level indicator consists of three blue LEDs on the body. The on/off switch is also designed as a rotary switch. There is also a bypass for separate connections or battery use. The drive lever is operated with the right index finger and, in addition to a turbo mode , has a locking screw for relieving the index finger and right hand. A recessed and retractable handle lever for better handling is attached to the screw guard. A detailed charge status view is obtained after unscrewing the head. Here the trim can also be varied using small lead plates. In its current state, the Suex is well balanced. The body is made of robust aluminum .

The scooter is in used but good condition. The battery still has a large part of its original capacity. It has always been stored in a cool and dry state between 30% and 70%. The Suex was basically only charged to 90%.

Available are:

  • Case with power supply
  • Trim Lead
  • Replacement handle
  • Attachment for separate parts on the handle such as compass, dive computer, lamp or camera.

The Suex can be visited by appointment or borrowed for a trial dive.

Decompression theory - Decompression during diving

The comprehensive book on decompression

Diving is more than just diving down and surfacing – anyone who wants to dive safely needs to understand what's happening in their body. In "Decompression Theory," Veronika Sievers and Dr. Dominik Elsässer explain the physical, physiological, and mathematical principles of decompression in a well-founded, understandable, and practical way.

From its historical beginnings with Haldane and Workman to M-values, Bühlmann's computational model, gradient factors, and the question of the best decompression strategy: this book provides a comprehensive overview. Why does decompression sickness (DCS) develop? Is it really just the bubbles, or do immune responses play a role? How do decompression gases and trimix affect decompression? What is the significance of the "helium penalty," deep stops, or the role of the endothelium?

Understandable and practical

This book is an indispensable companion for anyone wanting to delve deeper into diving theory – from dedicated recreational divers to technical divers. Besides the fundamentals of tissue saturation, half-lives, and M-values, it also covers advanced topics such as repetitive dives, decompression gases, oxygen windows, trimix, nitrogen narcosis, and the psychological aspects of decompression sickness (DCS).

With many practical examples (including subsurface diving) and a broad overview of the current state of research, "Deco Theory" offers a valuable wealth of knowledge for both beginners and experienced divers.

Perfect position

The wing was carefully designed to achieve perfect positioning in the water and comfort on the surface.

Unique NX Series harness

The NX harness is easy to put on and take off without compromising stability, comfort, or safety.

Compatible with two bottles

Thanks to its great flexibility, you can use your NX Series harness with two bottles by simply swapping the wing.

High lift and minimal drag

The position of the air in the wing ensures minimal resistance and prevents unwanted air pockets.

Incredibly robust

The double-shell Cordura wing is extremely durable and perfect for wreck diving.

Sell my rarely used submersible Bombard Explorer 550 Rib including 75 hp Mercuy four-stroke outboard. In addition, there is a Huminbird GPS echo sounder. Steering/drive lever, 20 l tank, stainless steel tank cage at the front, standing console, stainless steel roll bar with lighting etc. Private sale without guarantee/return. Engine has not been in the water since the last service. Hoses are tight, boat was always stored under tarpaulin, no water lounger. The trailer is not one of them! It doesn't belong to me either, so inquiries are futile. The boat can also be delivered to the northern Germany area after consultation and payment, if necessary. The boat is used and has signs of use! A heavily used tarpaulin is added to it. The boat has very good rough water characteristics and was unfortunately used far too little on the Baltic Sea. The 75 hp four-stroke engine is quite economical and with 6 divers the boat was fast. All you need is an unbraked 750 kg trailer
