NiTek Trio w/DSS Mount and Free Cover

The NiTek Trio is a three-gas Nitrox computer that is easy-to-read and easy to use:
  • Backlit 2.5-inch dot matrix LCD displays dive profile in a graph format
  • Diver can enter a custom display message
  • All three mixes are programmable from 21% Air to 99% Nitrox
  • A deep stop feature allows for required stops at deeper depths
  • Three user adjustable safety factor levels
  • Digital compass integrated into the dot matrix display

Nitek Trio with Depth-Compensating Wrist Strap Worn on the wrist or as part of an SPG console, the NiTek Trio turns on automatically upon descent and is an ideal primary or back up dive computer. Underwater, divers can switch between mixes with the push of a button. Using a modified Buhlmann ZH-L16 algorithm, the NiTek Duo can calculate decompression stop times for required stops as deep as 90-feet.

This computer has a user changeable battery. The battery is a CR2032 coin battery, the most popular coin battery in the world and very widely available. A battery will typically last over a year, even for very frequent divers.

The Trio is also an excellent 'digital gauge' for technical diving, see below.

Bungee Mount Front Bungee Mount Back In addition to the standard buckle wrist strap, every NiTek Trio from Dive Gear Express now also includes a FREE acrylic cover and the DSS Elastomeric Bungee Mount with 18 inches of bungee cord. The bungee mount securely retains the NiTek, is very low profile, makes it far easier to don than a buckled strap, and is depth compensating. The tough elastomeric material, remains flexible at low temperatures and the download interface cable can be attached without removing the NiTek from the mount. The photos show only one bungee lacing method, many more are possible.

Additional features include:

  • The NiTek Trio turns on automatically upon descent. Nitek Trio - Back
  • On the surface, the NiTek Trio displays a minimum of date, time and temperature when activated.
  • To conserve battery life, the NiTek Trio will enter the “Sleep” mode after several minutes of inactivity.
  • The NiTek Trio uses easily accessible and highly reliable push buttons instead of exposed electrical contacts.
  • The NiTek Trio can be programmed to monitor exposure to up to three different gas mixtures during a dive. All three mixes are programmable for mixtures ranging from air (EAN21) to EAN99. Underwater, NiTek Trio users can switch between mixes at the push of a button.
  • The NiTek Trio is capable of functioning up to a depth of 328 feet (100 meters) when in dive computer or gage mode.
  • The NiTek Trio automatically adjusts for altitudes up to 19,685 feet (6,000 meters).
  • The NiTek Trio has a digital compass integrated into the front-panel dot-matrix display.
  • The NiTek Trio displays a variety of data underwater including: date, time of day, current and maximum depths, no-decompression dive time elapsed and remaining, compass heading, and water temperature.
  • The NiTek Trio displays data specifically related to the use of Enriched Air Nitrox (EANx) including: fraction of oxygen (FO2) setting, partial pressure of oxygen (PO2), and an oxygen limit index (OLI) representing the cumulative effect of a diver’s exposure to elevated PO2s (the theoretical “CNS clock”) as a bar graph.
  • Through a combination of audible and visible alarms, the NiTek Trio helps to alert the diver to a number of possibly hazardous situations including: violation of ascent rate, nodecompression state, and whether mandatory decompression stops are necessary or if the diver has ascended above a mandatory stop ceiling.
  • Nitrox specific warnings occur when the diver approaches or exceeds a limiting PO2 of 1.6 atmospheres for all mixtures, and when cumulative exposure to elevated PO2s exceeds recommended limits. Nitek Trio with Acrylic Cover
  • The NiTek Trio can calculate decompression stop requirements for stops as deep as 90 feet (27 meters).
  • The NiTek Trio can be programmed to display data in imperial or metric units.
  • Dive depth can be displayed in fresh or salt water equivalents.
  • Special mode indicators make it easy to determine what display mode or screen you are in at any time.
  • The NiTek Trio has a back light to illuminate the screen, which can be turned on with the touch of a button.
  • The NiTek Trio’s memory capability enables it to hold and display log data on up to 30 hours of dive time or 60 dives.
  • Detailed dive-profile information can be stored for each dive through user-programmable sample intervals of 10 or 30 seconds (longer intervals allow data for a greater number of dives).
  • The NiTek Trio is the same physical form factor as the Duo, and the Trio will work with all Duo accessories, including the console and DSS boot.

Even today, with the popularity of technical dive computers, we still carry backup tables and many divers are seeking a solution for a good digital gauge. We suggest you consider the Dive Rite Nitek Trio, not as a dive computer, but in gauge mode as a digital gauge. The Trio has a backlit 2.5-inch display with very easy-to-read numbers. In gauge mode, the Trio displays a variety of gauge data underwater including: current and maximum depths, dive time elapsed, water temperature, and a digital compass. Other features include:

  • Officially rated maximum depth in gauge mode of 656 feet (200 meters).
  • Both audible excessive ascent rate alarm and visible indicator for ascent rate speed.
  • User settable audible alarms for depth, and dive time (i.e. alarm when a specific depth or bottom time is reached).
  • Configurable for fresh or salt water, imperial or metric operation.
  • 60 dive log with 30 hours of profile logs in 15 second intervals.
  • Automatically activates upon immersion in water.
  • Widely available CR2032 user changeable battery lasts approximately 3 years.
  • In gauge mode, the Nitek will not "lockout" after a missed stop or ascent rate violation.

These two graphics illustrate what you will see during the dive. This example is in metric (Meters and °C), but imperial (Feet and °F) can be configured as well. In "gage" mode the Nitek operates only as a depth gauge / bottom timer. It begins displaying depth and elapsed time once you descend below 5 feet (1.5 meters). While in gauge mode underwater, there are two screens you can toggle between. The primary screen displays current depth and elapsed time. The secondary screen displays maximum depth and lowest temperature reached during the dive. For both screens, the "Speed" bars at the bottom are graphic representation of ascent rate; more bars indicate faster ascent rate. In the upper right hand corner, the two symbols below the "Gage" symbol indicate the maximum depth and time alarms are enabled. In the lower right hand corner, the "Sea" indicates saltwater.

Time to Fly? Maybe Not.

Time-to-fly is the time you must wait between your last dive and ascending to altitude. Most dive computers display the amount of time remaining until residual nitrogen levels drop to the point where the computer considers a subsequent dive to be the same as a non-repetitive dive. This time may be described as a time-to-fly. However, even after considerable study, flying after diving recommendations remain controversial and continue to evolve. Decompression sickness statistics from Divers Alert Network (DAN) make it very clear that no current decompression theory and computer algorithm is able to account for all the complexities of decompression introduced by flying after diving.

Dive Gear Express encourages you to follow the May 2002 Flying After Diving Workshop recommendations published by DAN:

  • For a single no-stop-required dive, a minimum preflight surface interval of 12 hours is suggested.
  • For multiple dives in a single day, or multiple days of diving, a minimum preflight surface interval of 18 hours is suggested.
  • Wait substantially longer (i.e., 24 to 36 hours) if you have done any decompression-stop-required diving.
