FP-170. Nexus domeport How deep would you go?

Dear wetpixelmembers and specially Nexus owners!

I'm sure this has been discussed before here at wetpixel, but I couldn't find the thread so please excuse me asking the question again:

Planning to do some dives in the 60-65m range I would like to know if you have been at that deep with your Nexus FP-170 domeport.

Even it is rated to maximum 40meters by Nexus them selves, I think lot's of people have been much deeper with this port with no issues?

I hope this thread can help me to decide if I need a lot of luck to take this port to 60-65meters without implosion or if I can consider this as "Quite safe".

Thank you very much in advance from Kim Meineche.

I've had the 170 and the mini dome for the tokina down to 50 meters but I haven't done much diving beyond that.

Thanks for your info!

Talked to a friend of mine today who has a pressurepot that is big enough to contain the FP-170 port (Mounted with backcover).... think I am going to test the ports to 7,5bars in this and see what happens.

Good idea.... ???

The very best regards again from Kim! :-)
