| I have just looked at the map in the link mentioned above. I know this project cost a lot of money, a lot of time and a lot of divers.
This is the only proper survey of the site and it is trusted as it was done by a British dive magazine.
The Arch is shown as 52msw.
This is very wrong and I cannot believe that they made such a big mistake. Did they do it during a low tidal week?
It is mistakes like this that lead people to their deaths. You need to add 5msw to this to pass through safely.
It is popular with the final dive in the Extended Range courses. Mas depth in the course is 55msw. |
