NITROX
Among its many features, the adaptable Commander Nitrox, from Cochran
Undersea Technology, offers LCD backlighting; decompression ceilings down to
90 feet; zone or seamless altitude compensation to 15,000 feet; automatic
saltwater/freshwater compensation; automatic adjustments that consider
previous dive profiles, current temperature and ascent rate; personal safety
adjustments from 0 to 50 percent; a 100 dive logbook; and blend switching
(bottom blend up to 50 percent oxygen, decompression blend up to 99.9 percent
oxygen). The suggested retail price for the wrist mounted Commander is $680.
NEMESIS IIA NITROX
Cochran Undersea Technologys incredible Nemesis IIa Nitrox has all the
features of the Commander, plus a 300 dive logbook and hoseless air
integration (via a regulator-mounted transmitter). Thus, air supply and
breathing rate are factored into several calculations, including remaining
bottom time. It offers three blend switching, with the bottom blend
adjustable to 50 percent oxygen and two separate decompression blends
adjustable to 99.9 percent oxygen. There are several customizable alarms and
personal adjustments. The wrist mounted computer, Tank Unit transmitter and a
unique Field Programmer (not shown) are purchased together for $1,170.
EQUANO2X
Dacors EquaNO2x computer is activated by contacts and has a tap switch
operated LCD light and user replaceable battery. There are manual adjustments
for five altitude ranges, up to 11,480 feet. Personal adjustments can be made
for normal or hard diving conditions. In addition to visual indicators, there
are audible alarms for oxygen partial pressure violation, oxygen toxicity,
excessive ascent rate, entering decompression diving and exceeding
decompression stop ceiling. The suggested retail prices for the EquaNO2x are:
wrist mount $520, two gauge console with submersible pressure gauge $575.
NITROX RESOURCE
The Nitrox ReSource, from Genesis Scuba, is button activated (including its
Hydroglow backlight). It features automatic altitude adjustment from 2,000 to
14,000 feet, calculating depths in this range as occurring in fresh water.
The easy to understand display has prominent icons and a dive profile illustration.
There are color coded bar graphs for tissue loading, oxygen exposure and
ascent rate. The suggested retail prices for the Nitrox ReSource are: module
$376, wrist or hose mount $385, two gauge console with a submersible pressure
gauge (SPG) $475 and three gauge console with SPG and compass $510.
DATA PLUS
Oceanics Data Plus is button activated (the button also operates the
backlight) and offers automatic altitude adjustment from 2,000 to 14,000
feet, with dives in this range calculated as occurring in fresh water.
Graphics include a color coded tissue loading bar graph, oxygen exposure bar
graph and variable ascent rate indicator. If decompression is needed, the
computer calculates stops down to 60 feet. Oxygen partial pressures above 1.4
atmospheres are indicated by a visual warning. The suggested retail prices
for the Data Plus are: module $359.95, two gauge console with SPG $439.95 and
NavCon console with SPG and compass $479.95.
DATATRANS PLUS
Oceanics DataTrans Plus computer offers all the features of the Data Plus as
well as hoseless air integration (via a regulator mounted transmitter) and a
whole lot more. Additional graphics include breathing gas time remaining and
consumption rate bar graphs. There are many audible alarms, a few of which
include: five minutes of breathing gas remaining, entering decompression,
excessive ascent rate, gas time remaining equals decompression time, and high
partial pressure of oxygen. The suggested retail price for the wrist mounted
DataTrans Plus and transmitter is $949.95.
PILOT EAN
The Pilot EAN, from Orca, features finger contact activation and a tap switch
operated backlight. It has manually adjusted altitude settings for five
ranges from sealevel to 11,480 feet. Audible alarms include high oxygen partial
pressure, oxygen toxicity, excessive ascent rate and no decompression time
remaining at four minutes. Personal adjustments can be entered for normal or
hard diving conditions. The oxygen partial pressure warning can be set from
1.2 to 1.6 atmospheres. The suggested retail price for the wrist mounted
Pilot EAN is $469. In a two gauge console with a submersible pressure gauge
it is $559.
PILOT AUDIO EAN
Orcas Pilot Audio EAN offers all of the features of the Pilot EAN but can be
operated in normal or audio mode. In audio mode, the computer is worn on the
facemask strap, near the ear. It offers voice (spoken words) indication of
depth, dive time, no decompression stop time, reminder to check air, ascent
rate warning and entering decompression diving. The audio mode and backlight
are activated by a tap switch. An audible warning (beep) is always given to
remind the diver to make a safety stop on ascent. The suggested retail price
for the Pilot Audio EAN, which can also be worn on a wrist strap (included), is
$599.
SOLUTION NITROX
Sea Quests Solution NitrOX computer (manufactured by Suunto) tracks the
divers exposure to nitrogen and oxygen separately and offers graphic
representation of oxygen exposure, depth and ascent rate. There are audible
warnings for high oxygen exposure, entering decompression, excessive ascent
rate, ceiling depth exceeded and high oxygen partial pressure. The computer
can be set for three altitude ranges. (Selecting a higher than required
altitude range gives a personal safety adjustment.) The suggested retail
prices for the Solution NitrOX are: capsule $630; wrist mount $639; hose
mount $657; two gauge console, with submersible pressure gauge (SPG) $720;
three gauge console (one or two sided), with SPG and compass $765.
CHAMELEON
The Chameleon, from Undersea Breathing Sys-tems, is field upgradeable from
air only to nitrox compatible, which allows the owner to purchase one
computer that safely offers expanded features as the divers training
progresses. The Chameleon offers manual settings for five altitude ranges
from sealevel to 11,480 feet. There is a tap switch activated backlight and
personal adjustments for normal or hard diving conditions. Audible alarms
warn of excessive ascent rate, high oxygen partial pressure and exposure, and
a recommended safety stop. The suggested retail price for the wrist mounted
Chameleon is $299.
NITROX PRO
Undersea Breathing Systems Nitrox Pro has most of the features of the
Chameleon (plus it is always ready to handle nitrox or air). These include a
user replaceable battery, tap switch operated backlight, altitude and
personal safety adjustments, and ten dive logbook with profiles indicated.
Other offerings include an oxygen exposure bar graph and the diver can
manually enter a salinity correction factor for the diving medium, from zero
percent (fresh water) to seven percent. The suggested retail price for the
wrist mounted Nitrox Pro is $399.
NOVA
U.S. Divers Nova computer has three settings for altitude ranges from
sealevel to 8,000 feet. To increase personal safety, the diver can select a
range higher than that required. The computer is finger contact activated and
the backlight is activated by a tap switch. There are graphics for oxygen
exposure, ascent rate and depth. Audible alarms indicate entering
decompression, excessive ascent rate, ceiling depth exceeded and exceeding
maximum operation depth. The Nova has a 25 hour log and history mode. The
suggested retail price for the Nova in wrist or hose mount is $725.
ALADIN
PRO NITROX
Above 3,000 feet, the Aladin Pro NitrOX, from Uwatec, automatically sets
itself to one of four high altitude ranges. Using the optional PC interface,
the oxygen partial pressure warning level can be set from 1.2 to 1.95
atmospheres (settings greater than 1.6 are not recommended). Calculations
consider estimated skin temperature and blood perfusion, dissolved gases and
microbubbles. Audible alarms warn of excessive ascent rate, oxygen toxicity
and missed decompression stops. The suggested retail prices for the Aladin Pro
NitrOX are: wrist mount $795; two gauge console with submersible pressure
gauge (SPG) $915; three gauge console with SPG and compass $975; four gauge
console with SPG, compass and temperature gauge $995.
ALADIN
AIR X NITROX
Uwatecs Aladin Air X NitrOX computer offers all the features of the Pro
NitrOX plus several more, including air integration via the regulator mounted
transmitter. The remaining bottom time is based on the most critical of
several factors, including the preset (from 435 to 1,160 psi) tank pressure
minimum. Additional audible alarms warn of entering decompression diving,
high oxygen partial pressure, lost air data, remaining bottom time less than
three minutes and excessive breathing rate. The suggested retail price for
the wrist mounted Air X NitrOX and transmitter is $1,295.
