Zen/Nauticam 230mm glass dome depth rating?

What is the max depth rathing of the Zen 230 optical glass dome? I dont see it on their website. What is the max depth you have used it at? Is it ok to 70m? I beleive it is the same glass as the Nauticam 230mm, and Nauticam rate their dome to 40 M!!!

Thanks

Just off the phone with Alex T, and he informed me the nauticam 230mm is rated to 60m. Typo on one of their sites. Still intersted to hear what the Zen is rated to.

Hi nortoda1,

The Zen DP-230 is also rated to 60m. If anyone else is curious, the depth ratings are as follows:

DP-230 - 60m

DP-200 - 70m

DP-170 - 90m

DP-100 - 100m

Perfect, thanks burghaps :-)
