2003 - 2006: ALADIN TEC, VR3, Cochran EMC-20 H
Mix Gas Computers are the hype!
- Here we see the nice
- UWATEC ALADIN TEC
- designed like a watch, user replaceable battery
- EANx up to 100 %
- IrDA Interface, the box works down to 120 m
- Mountain Lake up to 4.000 m, dive time up to 199 min.
- with very nice statistic functions, very well known from the MicroBrain
- and a lot more very useful features
- the handling is very quick, no ramifications and, most of all: very intuitively
- as well with the ZH-L 8 ADT MB (adaptive for temperature and workload, micro bubbles) Algorithm
- and: 5 optional "level stops"
- I like this animal, wow!
- Level Stops in comparison to the complete time-to-surface (TTS), for a dive: 42m, 25 min.
Level first, deepest Stop / first stop time TTS
--- m / min. [min.]
L0 9 3 36
L1 12 1 40
L2 12 3 45
L3 15 1 50
L4 15 3 57
L5 18 2 65
- the DECO 2000 table gives us at: 42 m / 25 min.:
- 12 m / 1', 9 m / 4', 6 m / 8', 3 m / 16', i.e.: TTS = 29 + 4 = 33 min.
- in comparison with the D.C.I.E.M. dog:
- 9 m / 7', 6 m / 8', 3 m / 17', TTS = 36 min.
- and, old mother U.S.N. Table:
- 6 m / 2', 3 m / 14', TTS = 19 min.
Presently we are making in-depth tests with it, as well with: COCHRAN EMC-20H and NiTek He.
- as it was written once upon a time in one of these countless divers mags:
- "charming like a bolt gun" ...
- the VR3 for open circuit (SCUBA)
- Air, Nitrox, Trimix, Heliox
- Color Display with sort-of integrated XBOX ( :-)) )
- the dive simulation for 42 m / 25 min. gives us:
- 25m/2', 17m/2', 9m/2', 6m/8', 3m/22', i.e.: TTS 40 min.
- what is really ridiculous: the arm strap (well, for that price !!!)
- and the really lousy manual (details, completeness, ..)
- battery replacement, even when done within 3 minutes, puts the box into e-oblivion (complete loss of data ..)
- the housing is more or less the bulk aluminum,
- but the whole (computer, strap, manual, accessories) looks like a botched job...
- especially the extremly silly deep stop calculations
- which puts the deco prediction and, as well, the diver himself, at the verge of going nuts
- and here comes the best feature ...
We are testing in open water, in our recompression facility and for the fun of it, we are doing a saturation dive with them.
(well, if i am in a bad mood, i will drop the boxes to the bottom of our oil rig and
leave them there for a couple of days ....)
As soon as we have the results, we are going to publish a small comparison chart
with the features, the bugs and the overall handling and the responsiveness and competence of
the technical support.
- this one is the latest from the COCHRAN family
- these boxes have an United States Navy certification:
- they are robust and reliable!
- this company has an ISO 9000 certificate, and, as well the civilian computers have a CE quality sign
- the field failure rate is below 1 % !
- here we see the EMC-20 H
- EMC - 20 H means:
Environmental Microbubble Consciousness 20 halftimes, Helium
- the computer comes completely with:
- a robust box for transportation, a display protector, all of the manuals and flow charts on one CD,
- as well with the ANALYST Desktop-Deco-Software (on another CD) with an USB Linkadapter
- here a screen shot of ANALYST Version 4.01.k
- the whole set-up, including the arm strap and the housing, looks very, VERY professional!
- this one is good for 3 arbitrary mixes ( 3 * fO2 ), and, as well:
- for rebreather operation (CCR) with 2 set-points ( 2 * pO2 )
- as well with a brandnew silver Quarter !!!
- :-)) for the operation of the electrical contacts
- and as battery replacement tool ...
- with 20 compartments from 1.25 min. to 950 min.
- depth up to 130 m
- Super Features like:
- automatic adaption to fresh / saltwater
- automatic temperature adaption
- logging of up to 1,500 hours of diving
- file transfer of logged dive data directly to DAN
- here some technical information directly from the manufacturer
- and as well a compilation of NDLs in relation to the conservativism factor
- the simulation with my "Lake of Constance" Standard Dive ( 42 m / 25 min.) yields:
- Conservatism = 0 (=Minimum): 18m/2', 9m/2', 6m/3', 3m/8', i.e.: time-to-surface: 15 min.
- Conservatism = 10: 18m/2', 9m/3', 6m/4', 3m/10', time-to-surface: 19 min.
- Conservatism = 20: 18m/2', 12m/1', 9m/3', 6m/4', 3m/13', time-to-surface: 23 min.
- Conservatism = 30: 18m/2', 12m/2', 9m/3', 6m/5', 3m/15', time-to-surface: 27 min.
- Conservatism = 40: 18m/2', 12m/2', 9m/4', 6m/7', 3m/17', time-to-surface: 32 min.
- Conservatism = 50 (=Maximum): 18m/2', 15m/1', 12m/3', 9m/4', 6m/8', 3m/19', time-to-surface: 37 min.
the first results from our tests:
- after a lot of air-, nitrox- and mix gas dives in the Red Sea and in Thailand
- with SHE- and HE-Divers of various skill levels
- Divemaster, Instructor, Techie, Tec-Instructor, Course Director, etc.,
- we have compiled a short list with the results
- the ALADIN TEC is an unofficial competitor because it isn't a Helium computer
- but anyhow we checked it on purpose, just to demonstrate, how easily a well-designed box can out-perform
- as well we didn't compare deliberately all the features on a 1:1 basis
- because there is already more than enough material on the manufacturers homepages!
- here is a small PDF with our findings!
- as well results of the workshop 2006 Smithsonian Institute from my friend Karl Huggins
- Have Fun with it!
