Mares Abyss 22

[cpd123]

I recently checked Mares's website and saw there was a new model of the abyss 22. Does this have the same internal "guts" as the old model (2005)? Also If the regulator is different, does anyone know where i can obtain an updated service manual?
Thanks

My understanding is that the changes are purely cosmetic.

Here is what I know about the new Abyss 22 which won't be available until late-April 08'

MR 22T first stage
New first stage with nickel- and chrome-plated forged brass that stands out from previous versions because of its lower weight. This was made possible thanks to innovative technical solutions that still maintain the same internal components. Diaphragm technology with the DFC system and replaceable high-pressure seat connector. The high-pressure valve is made of "Tri-material" allowing for superior safety and duration. It is fitted with a preferential intermediate-pressure DFC port with a ½” UNF connection to the primary second stage hose, 3 other 3/8” UNF threading LP service ports, and 2 high-pressure (HP) ports with 7/16” UNF threading. The latter are inclined at a 45° angle to allow for a more intuitive layout of hoses or of the transmitting unit of the integrated dive computers.

Abyss second stage
Second stage with V.A.D. system, made of nickel- and chrome-plated brass. This material offers a number of benefits: Absolute ruggedness. Thinner walls make for a more compact size without the need to resort to a smaller diaphragm, resulting in less drag in the water. Anti-freeze function, facilitated by the“radiating action” of the metal.
More natural breathing: The metal walls of the second stage “capture” the humidity contained in the air breathed, and return it during the inhalation phase, thus limiting the common “dry mouth” phenomenon that is caused by breathing overly dry air.
The lid features the “Mesh-Grid” system to optimize the incoming and out-going flows of water, which offers additional improvement in performance.
The mouthpiece is made of soft hypoallergenic silicone, limiting jaw fatigue and offering a secure fit even after very long dives.
