Dear Authorized SCUBAPRO UWATEC Dealer,

This is a communication to you, our dealers, to inform you we are in the
preliminary stages of an upgrade program for the MK20 first stage
regulators.

Recently, we were notified that a diver had reported a crack in and
around the body of a MK20 first stage regulator where the yoke retainer
seats against the internal body of the regulator. We immediately
conducted an internal review utilizing our SCUBAPRO ® Engineering Team.
Simultaneously, we asked the independent experts at Exponent Failure
Analysis Associates to determine the root cause. Exponent is a leading
failure analysis consultancy with technical expertise spanning a wide
range of scientific and engineering disciplines.

Exponent has completed an extensive and comprehensive independent review
and analysis of the MK20 design and materials, as well as detailed
inspection and analysis of both the failed unit and properly working
MK20s. They determined the crack occurred due to a combination over
torque and exposure to an underwater environment. The crack may be
initiated if exposed to over torquing and over time, a larger crack may
develop when exposed to harsh environmental conditions and, in a small
number of cases cause a failure.

As a result of these findings, SCUBAPRO’s engineering staff and Exponent
both recommend that all MK20s be updated with Universal Yoke Retainer
(PN 10.103.115). This retainer transfers the mechanical load to the yoke
retainer and not the body. The upgrade to this Universal Yoke Retainer
and proper torque settings have been found to eliminate the stress
placed on the body of the regulator at the location of observed
cracking. This update, available in both Yoke and DIN, will soon be
available to you to so that you may update your customer’s MK20 first
stages. We will be mailing each Authorized Dealer more correspondence on
this program within the next week.

In closing, we work hard to earn the trust of you and your customers
every day, and know that our reputation is based on what we do, not what
we say we will do. That is why when we first learned of a problem, even
though it involved a product no longer produced or sold, we took
responsibility and immediate action. At SCUBAPRO diver safety comes first.

Please feel free to contact your Sales Representative or our Technical
Services Department if you have any further questions.

wobei mich ja nun schon interessieren würde, was sind denn bitte "harsh
environmental conditions"

Baggersee-Tauchen?

Moin,

der Oliver Schommer wäre m. E. gut beraten, sich die FAZ und Süddeutsche
am Samstag zu kaufen wg. Anzeigenteil.

Der toppt sogar noch Herrn Michl von ex Mares.!

So ist's recht, erstmal Kompetenz behaupten.

Kein Wunder, wenn man das auch _unterwasser_ benutzt. Wie kann man nur.

Du nimmst meine Frage vorweg.
Womöglich Salzwassertauchen? Oder gar nachts...?

Scubapro erlebt offenbar, das es sich nicht auszahlt, wenn man Designer
und Marketingster an einstmals bewährten Automaten rumpfuschen lässt,
nur damit man einen immerwährenden Fortschritt behaupten kann ( TIS und
Co, Niro raus, Messing rein, Messing raus, hüh und hott), oder damit die
ersten Stufen modisch mit Miniröckchen aus Plastik und Wespentaille
gestylt werden.

Grüße

Nu, Stefan hat jedenfalls Ahnung von Technik!.
