A few more points on the Mares team vs. Apeks discussion.
I purchased a Mares Abyss after some research and I'm very happy with it. Aside from some of the shortcomings mentioned, such as stiff hose, uncomfortable mouthpiece, rather heavy second stage, and price - shop around. The benefits greatly outwheigh it, such as: ease of breathing, rugged metal construction for second stage and yes - no adjustments.
I prefer many of my products to be automatic for personal convenience and ease of use so I can concentrate on enjoyment and other tasks. Aside from a few surface free flows which can be easily corrected or prevented with proper positioning in water, its been flawless under water.
I know some of you hard core manual fans will dispute this, but I believe a good automatic adjustment which sets breathing resistance at uptimum to prevalent conditions is superior to the less accurate human adjustment which may be further compromised by impaired judgement
Just like some driver enthusiasts swear by a manual transmission in sports or race cars, even though automatic transmissions can make a car faster.
I am a rookie diver so I can not make an experienced comparison as some of the very experienced, expert divers on this forum have. While I certainly value these qualities I take them with a grain of salt for the following reasons:
While I have no doubt Apeks are excellent regulators, why always point to the competitions weaknesses and your products strength? What are the weaknesses of Apeks regulators, or have they achieved what mankind has been striving for - "perfection"?
Many of you Apeks fans out there sound like the Apple computers
fanatics when it comes to pc's.
I went to the respective company websites and saw the U S Navy Breathing Work charts they list, the one for the Mares was superior to the Apeks TX 50, 40, and 20. The TX100 was'nt listed, but Rodales Mag. claims its the best breathing reg they have ever tested. Fair enough?
