Hi folks, we could first speak about Nitrox Scuba Diving and why or why no longer nitrox is vital. Then we’re going to get into the great Dive Computers on the market today, the Oceanic Atom 2.0 and the Dive Rite Trio Technical Computer. Everyone people have 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%). And a touch bit of trace elements like carbon monoxide, carbon dioxide, smog, arsenic, cigarette smoke, and so on. 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% of 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 whilst they say “nitrox,” so do I further right 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. In case 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 bottom line, you can live at 100 fsw for 40 mins, in place of the 20 mins that your dive tables let you know.
Equipped with all of the same old dive laptop functions, the Atom 2.0 measures temperature, intensity, dive time, and no-decompression limits over more than one dives. It will feature paintings with air and nitrox and could operate in regular time mode whilst you’re now 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 display the tank stress of 3 specific tanks simultaneously, 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 manner to preserve a watch at the ultimate air of either your friend or student.
Multiple-Gas Mixes
The Atom 2.0 can deal with up to a few one-of-a-kind gas mixes containing 21-100% oxygen or even permit you to switch gases at some stage 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 is a large time and price saver that allows the 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 in your logs to hold music of dive sites, dive pals, and notes. Unfortunately, the software program is best available for PC.
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 now not go back to the Main Dive display screen whilst the divers switched the devices from Gas 1 to Gas 2 in the course of 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 have to discontinue all diving activities with this pc until a software program upgrade has been carried out via Oceanic, your neighborhood Authorized Oceanic Retailer or sent back to us. So beware whilst buying this pc used. If you’re going to make this buy, seriously recollect buying a brand new unit.
Conclusion
The Oceanic Atom 2.0 is a top-notch package deal 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 with the aid of offering a user-replaceable battery and each other fantastic function a diver could wish for. Maybe not quite an appropriate accessory to a 3 piece fit, but it virtually works with pretty much any other outfit with incredible functions and sporty styling.
Dive Rite Trio Dive Computer
This is a real technical pc for the recreational and technical diver. 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 is a great primary or again up dive 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.
