Nitrox Scuba Diving, & Two Dive Computer (Oceanic & Dive Rite) Reviews

Hi folks, lets first discuss what Nitrox Scuba Diving is, and why or why not nitrox is important.

Then we're going to get into the best Dive PCs on the market today the Oceanic Atom 2.0, and the Dive Rite Threesome Technical PC . Everybody of us has breathed nitrox. Nitrox means a mixture of nitrogen and oxygen and the word "nitrox" does not tell the relationship of those elements. So air is nitrox too as it contains ( basically ) nitrogen ( 78% ) and oxygen ( 21% ) .. And a little bit of trace elements like carbon monoxide, carbon dioxide, fog, arsenic, ciggie smoke. .etc. .The base of word nitrox is the expression Nx / Ox, where N is the chemical sign of nitrogen and O is the chemical sign of oxygen. So as an example N ( fifty ) O ( fifty ) would be fifty percent oxygen.

.Also EANx40 label is employed sometimes ( the letter "x" is saved in the label ). Sometimes folk mean EANx when they assert "nitrox", and so do I further here. Then we are saying that the mix is hypoxic, ie.

It has less oxygen than 21%.) = eighty fsw! At EAN32 ( that is 32% oxygen ) you get a twenty percent get out of jail free card. If you dive to one hundred feet of seawater ( fsw ) you can work it out at 80 fsw ( one hundred - ( a hundred x twenty p.c.) = eighty fsw!

And using the rule of 120 ( 120 - depth = time ) 120 - eighty = forty mins so bottom line, you can stay at one hundred fsw for forty mins, rather than the twenty mins that your dive tables tell you.

The Dive Rite TRIO  3 Gas Dive Computer:

This is a real technical PC for the recreational and technical diver. The new NiTek TRIO is a three-gas Nitrox PC that is easy-to-read and simple to use. Worn on the wrist or as a part of an SPG console, the NiTek Threesome turns on mechanically on descent is the ultimate first or back up dive PC. Underwater, divers can switch between mixes with the push of a button. On surfacing, the NiTek Threesome will maintain the gas mix entered till midnight, when it clears and must be reset next day. Employing a changed Buhlmann ZH-L16 algorithm, the NiTek Threesome can work out decompression stop times for needed stops as deep as 90-feet. It includes all of the features of the favored NiTek DUO, and the following new features : one. Dot matrix LCD displays dive profile in a graph format two. Diver can enter a custom message of almost 8 ( eight ) characters in 2 rows which will display at the head of the screen 3. All 3 mixes are programmable from 21%-99% Nitrox four. A deep stop feature allows for safety stops at deeper depths five. 3 user adjustable safety factor levels six. You'll see this product branded by Zeagle as the N2ition, TUSA as the Hunter, and a large number of others. What i have found out, and this isn't reflection on Dive Rite, of which we are definitely a proud dealer, is that as the scuba market is so small, Seiko wields its strong hand and restricts the guaranty on this unit. Leaving Dive Rite and the others holding the bag should a unit go bad in 2 years. It is ludicrous to only guaranty a $450 technical PC for a period of a year. .stay tuned for details. Conclusion The NiTek Threesome uses the Bulhman algorithm like the NiTek Pair and other Dive Rite computers. The deep stop feature isn't new gradient factors in the PC, but instead a straightforward method of incorporating deep stops without adding time to the less deep stops. When deep stops are turned on it will add deep stops to any dive with over five mins of decompression. Deep stops are figured out by splitting the difference between max depth and the 1st booked shallow stop.

As an example if you're making a 100' dive for sixty mins and have a 30' stop the 1st deep stop will be at 60' for one minute. It will continue giving you one minute stops each 10' till you're able to the booked 30' stop. The Threesome is not built to be a technical PC, but a complicated recreational PC. It does not do Trimix so deep stops won't be correct for helium.

The Threesome will slow your ascent and let you do deep stops without suffering increased time at less deep stops. Thanks for reading.
