The Newtsuit is an
atmospheric diving suit
An atmospheric diving suit (ADS), or single atmosphere diving suit is a small one-person articulated submersible which resembles a suit of armour, with elaborate pressure joints to allow articulation while maintaining an internal pressure of on ...
designed and originally built by
Phil Nuytten.
The suit is used for work on ocean drilling rigs, pipelines, salvage jobs, and photographic surveys, and is standard equipment in many of the world's navies.
This aluminum hard suit has fully articulated,
rotary joints in the arms and legs that give the pilot a great range of mobility.
These joints operate freely at high pressures. At the time the suit was constructed, it was the first of its kind in this regard. The pilot can control objects and handle tools with manipulator jaws at the ends of the arms. Although the suit is certified to , it has been tested to .
The suit can be operated untethered, with a thruster pack that can be fitted to the suit. This allows mobility in mid-water.
The Newtsuit navigates with foot controls. The left foot provides vertical control, with the right foot providing lateral control.
Other equipment that can be attached includes twin video cameras, colour imaging
sonar
Sonar (sound navigation and ranging or sonic navigation and ranging) is a technique that uses sound propagation (usually underwater, as in submarine navigation) to navigate, measure distances ( ranging), communicate with or detect objects o ...
, and an AMS suit monitor system that transmits information to the surface, such as CO
2, HPO (high pressure oxygen), O
2%, depth, temperature, and cabin pressure.
Communication is achieved through digital voice/data transmission via water and
umbilical cable
An umbilical cable or umbilical is a cable and/or hose that supplies required consumables to an apparatus, like a rocket, or to a person, such as a diver or astronaut. It is named by analogy with an umbilical cord. An umbilical can, for example, ...

rebreather
A rebreather is a breathing apparatus that absorbs the carbon dioxide of a user's exhaled breath to permit the rebreathing (recycling) of the substantial unused oxygen content, and unused inert content when present, of each breath. Oxygen is a ...

Xenon
Xenon is a chemical element; it has symbol Xe and atomic number 54. It is a dense, colorless, odorless noble gas found in Earth's atmosphere in trace amounts. Although generally unreactive, it can undergo a few chemical reactions such as the ...
strobe
A strobe light or stroboscopic lamp, commonly called a strobe, is a device used to produce regular flashes of light. It is one of a number of devices that can be used as a stroboscope. The word originated from the Ancient Greek ('), meaning ...
