Review of AquaTec Atlas Tec

AquaTec Atlas Tec BCD

Today I will be reviewing the AquaTec Atlas Tec BCD. Now here is a thing you all have to be aware of. Aquatec has a strange naming system which goes like this: Name, Name Tec, Name Pro. Here is the difference. Just the name means you only get the basic BCD. If it has Tec next to it, you get a weight integrated version of that BCD, and finally, Pro is the weight integrated BCD with an alternate air sourse power inflator. Now, I've got the Atlas Tec which mean I have the weight integrated. Now, if you have started reading from my first review, you'll be wondering why would I be reviewing an already well known and well reviewed product. Here's why:





AquaTec Weight Integrated, Quick Release System (Closed)



AquaTec Weight Integrated, Quick Release System (Opened)





Spot the difference? No? WHAT!? Ok, ok, here is a Northern Diver Atlas:

Please note: I do not have any affliation with this dive shop. I have simple borrowed their picture because my Sony A350 is rubbish unless the object is well lit, and I cannot do that becaue I currently do not have a studio.





Thats right. AquaTec has actually listerned to its customers and changed the weight integrated system and its quick release system.


The Aquatec Atlas was famous for three things. Being the same as the Northern Diver Atlas at a fraction of the cost. Divers loosing the weight integrated bags while diving, and finally, the power inflator going free flow on the horns. Here's what Aquatec has done. They have changed the weight integrated system, but still offer to replace the bag, if you ever do loose it while diving, through no fault of your own. And they offer a limited life time warranty on the whole BCD, so they will fix or replace your power inflator. And unlike the annoying Oceanic limited lifetime warranty, which you have to registor with in a certain period of time, they come with the limited lifetime warranty just with purchase, as it should be with warranties. But the really great thing I found was that the local distributor actually offered to whole his own class for people to learn and maybe service their own BCD, regulators, etc. The only other company I found that offered to hold its own courses were Zeagle and I was very temped to buy Zeagle just on that fact alone, even if they were roughly 4000kms away. Some people should learn from these examples, cough, cough (I'm looking at those people who promised, but never delievered). I might be sounding very bias right now, but I gain no profit from this. Heck, I even had to buy this stuff myself to just review them. I just really, really like having the option of self servicing, even though I will never self service(yes, after 3 broken laptops and a PC into this self servicing business, I learnt that I wasn't born to self service).



Back to the review, the AquaTec Atlas Tec is a nice large BCD with 4 metal D rings, large pockets with web/net bases so whatever water that has gathered in those pockets will drop out pretty fast when you walk out of the water. The weight integrated system was easy enough to use, but would have liked a manual release button instead of pulling on the tabs all the time. Its also got a nice Stainless Steel Tank Cam Lock Buckle and can be upgrade to carry two tanks. Unfortunately, I seem to find AquaTec's rubber products to be flimsy and could have used some scissors works to trim the long hanging left over threads. Am I asking for too much? Yes, a good scissors work is hard to come by even in expansive handbags, so what am I expecting. One thing that really got me though was the plastic zippers. Sure, plastic doesn't rust and will keep the zipper working well, but it just doesn't have the same feel of a metal zipper. Another thing which people might find hit and miss with is the size of the BCD itself. I, being a fat, short person, usually wear a medium large, but if they only have medium or large, then I'm usually screwed. Strangly enough, this wasn't the case for the Atlas, as the medium fit me (to borrow another manufacturer's phrase) like a glove. Usually a large BCD leaves me hanging off of its 'wings' and the shoulder straps floating where my head should be. Another reviewer(far more experienced than myself), concluded the AquaTec Atlas as 'too average'. Well, maybe his had one too many high end BCDs sent to him, cause from where I'm standing, this BCD is one of the better budget BCDs out there, pacted with features. So, if you are low on cash, might want to have a look into this BCD.




Review of AquaTec Mark II (RG-2000)

AquaTec Mark II (RG-2000)



I assume most of you are here because you, like me, could not find any reviews on AquaTec products, or just wanted to learn a little bit more.
Today, I'll be reviewing the AquaTec Mark II or RG-2000. This review will be comparing the Mark II with the Oceanic Alpha 8 SP 5, as the AquaTec is in a similar price range.
Suprisingly for its low budget, the Mark II comprises of 2 HP(High Pressure) ports, compared to that of the slightly more expansive Alpha SP 5. Also, the Mark II is an enviromentally sealed regulator and the LP(Low Pressure) ports are on a different part of the first stage to the HP ports, allowing the reg and octo to move while the gauge would stay put. Of course, the famous,but more expansive Alpha SP 5 does not have any of the mentioned features.
High featured as the Makr II was, the one I got had very minor cosmatic features, which I'm sure if I asked nicely enough to the distributers, they would swap for another. One last problem I did find on the first stage was that the HP and LP ports used different sized allen(hex) keys. The LP used the standard 4mm allen key, but the HP ports used a rarer 4.5mm allen key(this is only a rough assumption as it is the allen key between 4mm and 5mm). Moving on, the second stage was also packed with features like pre-dive and dive mode and some kind of an air flow adjustment screw. Unfortunately, the Mark II felt much more flimsier than the Alpha 8 (if you have noticed that I have changed the Alpha SP 5 to just Alpha 8, that is because Alpha's first stage is called SP 5 and the second stage is called Alpha 8, not a mistake on my part by all means).
Also the second stage itself was much bigger compared to the tiny Alpha 8, like comparing an orange to a mandarin. I'm not saying bigger is better, I actually kind of liked the tiny Alpha 8. I'm not sure if the large size of the second stage regulator had influnenced the size of the mouth piece, but it was uncomfortably large for my small mouth which had grown accustom to the BOSS Elite Balanced Diaphragm regulator set which I was using until now. This is not a problem as a mouth piece can easily be changed and I was sure it would take me no time to get used to them, as they were of a very soft silicon compared to that of the Boss eilte. You have to remember before you take this second stage for a dive, you have to change the air intake, otherwise, you will feel so much air is coming out, you can breath at all, or the air just doesn't come out. Another big difference was the purge button, which was much harder to press on the Mark II than the Alpha 8, which I can only attribute to Oceanic's experience in the market. This may not be an error on the part of Aquatec, as if you take the inter-switchable coloured purge button off, you find an amazingly soft purge button underneath. I couldn't tell if they had just made the cover too thick and hard or made it purposely hard so you couldn't accidently purge is very unclear as AquaTec's website has no information apart from the very basic.
Infact, this is all it said:



-----



• 2 high pressure ports (7/16-20 UNF)

• 4 low pressure ports (3/8-24 UNF)

• First stage uses a pneumatically balanced diaphragm design

• Built in swivel on the low pressure port reduces the stress on the hose connections

• Second stage is a downstream demand valve with twin air intake control



The MARK II Regulator (RG-2000) contains: One unit of the RG-2000 First Stage and One Unit of the RG-2000S Second Stage maximum Intermediate pressure: 125-160 PSI. Inhalation Effort: 0.0-0.2 CIW (Column inches of water).



Exhalation Effort: 1.1 CIW

This rg-2000 looks alot like a rg-1002 from:

http://www.aquateccanada.ca/product/RG-1002


and it got a little more information compared to that of the USA site, but they do not have the Mark II second stage, which in USA is called the rg-2000s.
