Hi folks, We could first discuss Nitrox Scuba Diving and why it is no longer vital. Then, we will get into the great Dive Computers on the market today, the Oceanic Atom 2.0 and the Dive Rite Trio Technical Computer. Everyone has breathed nitrox. Nitrox means a mixture of nitrogen and oxygen, and the phrase “nitrox” doesn’t tell the relationship between those factors.
So air is nitrox, too, as it incorporates (essentially) nitrogen (78%) and oxygen (21%). Some trace elements are carbon monoxide, carbon dioxide, smog, arsenic, cigarette smoke, etc. The base of the phrase nitrox is the expression Nx/Ox, wherein N is the chemical sign of nitrogen, and O is the chemical signal of oxygen. So, as an example, N(50)O(50) might be 50% oxygen. So basically, nitrox can be any blend of nitrogen and oxygen containing 1 to 99% oxygen (and relaxation is nitrogen).
Back to our tale. Also, the EANx40 label is used now and then (the letter “x” is preserved in the label). Usually, people mean EANx while saying “nitrox,” so do I go further here? Then we say that the mixture is hypoxic, ie. It has less oxygen than 21%. Hyperoxic nitrox is EANx, and normoxic nitrox is essentially air, 21% of oxygen, and 79% nitrogen. If you dive to one hundred feet of seawater (few), you could calculate it at eighty few (100 – (100 x 20%) = 80 fsw!
At EAN32 (32% oxygen), you get a 20% get-out-of-jail unfastened card. If you dive to a hundred ft of seawater (few), you may calculate it at 80 few (100 – (100 x 20%) = 80 fsw! And using the rule of a hundred and twenty ( 120 – intensity = time), 120 – 80 = 40 minutes, so the bottom line is you can live at 100 fsw for 40 mins; in place of the 20 mins, your dive tables let you know.
Equipped with the same old dive laptop functions, the Atom 2.0 measures temperature, intensity, dive time, and no-decompression limits over more than one dive. It will feature paintings with air and nitrox and could operate in regular time mode while you’re not underwater. It can also be utilized in gauge and unfastened-diving modes with modifications for altitude. The Atom 2.0 is person-changeable between Metric and Imperial.
Air Integration
Using up to a few transmitters, the Atom 2.0 can simultaneously display the tank stress of 3 specific tanks, allowing it to behave as 3 SPG in a single. The Atom 2.0 can also be operated in buddy mode to permit the computer to test for and display another transmitter’s air pressure inside 4-6 ft of the laptop. This is a tremendous way to preserve a watch at either your friend’s or student’s ultimate air.
Multiple-Gas Mixes
The Atom 2.0 can handle up to a few unique gas mixes containing 21-100% oxygen or even permit you to switch gases at some point in the dive. This function makes it mainly appealing to deep and technical divers.
User-Replaceable Battery
This is one big gain that Atom 2.0 has over its competitors. The computer is powered via a CR2430 battery that may be effortlessly bought at a normal watch shop and replaced with the person’s aid. This large time and price saver allows Atom 2.0 to stand out from the p.C.
Dive Logging
The Atom 2.0 comes with a USB interface and OceanLog PC software to permit dives to be easily logged to your computer. The dive facts are easily formatted for smooth reference, sorting, and printing. The software allows you to add additional information to your logs to hold music from dive sites, dive pals, and notes. Unfortunately, the software program is the best available for PCs.
Oceanic has been knowledgeable using it is provided that they had obtained remoted reviews that two Atom 2.0 dive computer systems locked into the Gas Switch-to display screen and did not go back to the Main Dive display screen whilst the divers switched the devices from Gas 1 to Gas 2 during dives when they were simplest the use of one transmitter, and Pressure related to Gas 2 turned into being provided through an Analog Gauge.
You must discontinue all diving activities with this computer until a software program upgrade has been carried out via Oceanic, your neighborhood Authorized Oceanic Retailer, or sent back to us. So beware when buying this computer used. If you’re going to make this buy, seriously consider buying a brand new unit.
Conclusion
The Oceanic Atom 2.0 is a top-notch package of dive gauges in a neat, sporty little wristwatch. The handiest area it falls quickly of being the whole package deal is not having a built-in compass (the new Oceanic OC1 now DOES come with a constructed-in virtual compass). However, it makes up for this shortcoming by offering a user-replaceable battery and other fantastic functions a diver could wish for. It may not be an appropriate accessory for a three-piece fit, but it virtually works with any other outfit, with incredible functions and sporty styling.
Dive Rite Trio Dive Computer
This is a real technical PC for recreational and technical divers. The new NiTek Trio is a 3-gas Nitrox computer that is straightforward to examine and easy to apply. Worn at the wrist or as part of an SPG console, the NiTek Trio turns on mechanically upon descent and is a great primary or, again, updated computer. Underwater divers can transfer between mixes with the frenzy of a button. Upon surfacing, the NiTek Trio will maintain the fuel combination entered until the middle of the night while it clears and should be reset the following day. Using a changed Buhlmann ZH-L16 algorithm, the NiTek Trio can calculate decompression stop instances for required stops as deep as 90-toes.
