Do yourself a favour and buy a vacuum valve kit. It will be the best investment you can make

The Nauticam is an excellent design and it would take a phenomenal effort to pull it from the housing. I dive in a river quite often and it is extremely mucky, when removing the viewfinder to check the o-rings they are always spotless. From memory the Ikelite is a Inon. The below from https://www.uwcamerastore.com may suit your needs.

I use a Nauticam 45 on an ikelite housing, cost $500 used and around $100 for the adaptor. Works perfectly

Try 15 more pumps once the light goes blinking green and let us know what happens. My surveyor is a sort of hybrid, I use the surveyor electronics with an ikelite valve & pump. It is somewhat unreliable at around -5 in/hg but much more reliable at -10 in/hg

What pressure are you vaccing down to?

Have you tried a new battery?

Thanks Leslie Much appreciated

Hi All Any ideas on this one? Found in Saltwater Mooloolah River QLD Australia 10mm 5.0M Depth 19 degrees C

A Lovely retrospective, you have travelled to some gorgeous places. Your images took me on a great journey. Did you draw the original critters at Lembeh blue ring design?

Found one!! Thanks,

Hi All As the title says, I am looking to buy an Ikelite 5510.50 port extension. Posted to Australia payed via Paypal and happy to pay the %3 and shipping

Thanks for the link mate, I will check it out

Well spotted, mine has the hot shoe sync connector mounted in it. If I didn't occasionally use a flash that would be the ticket. Congrats on becoming a Mod!

Thanks Chris, I appreciate the comments. That is the correct type of housing I originally thought the back plate was the place to install it but after some consideration I am not too comfortable having a protruding object near the viewfinder, where my face/eyes will be while getting pounded in the surf. I am thinking the RHS has enough flat real estate and has less chance of poking me in the eye. Housing definitely seems thick enough to accept a decent thread. The ikelite valve also comes with a locknut. I will take some measurements to see if the thread will protrude out enough to accept the lock nut. Next issue will be sealing. As you say the housing is slightly textured, at least PE is easy to sand smooth.
