Take your housing and vacuum unit to a local machine shop and tell them you need it to be drilled, tapped and spot faced fo your vacuum unit.

Or send it to Reef Photo & Video. They advertise on this site!

#392374 Nauticam Vacuum valve - how much vacuum?

Posted by okuma on 14 February 2018 - 10:47 PM



I believe you are overly concerned about this. We have Vivid units on our housings and use a small hand pump.

 I pump till I get a green light and then two extra strokes. We do this 1/2 hour before diving and as long as it stays green, then good to go.


Over pumping will eventually cause your housing to collapse and eventually get sucked up into the pump! :laugh:

#392144 1 Inch ball mounts o-ring size

Posted by okuma on 07 February 2018 - 07:39 PM

From ULCS web page:

""BUNA O-Ring, Size 2-209." If you can not locate o-rings at a plumbing store then your local hardware store, Lowes, Home Depot, ACE, OSH sell them in one-packs from Danco # 95. (The size is 15/16 X 11/16 x 1/8)."

#392073 air travel with strobes (air pressure effects)

Posted by okuma on 05 February 2018 - 08:09 PM

Underwater equipment is designed with O rings/seals for a higher ambient(outside) pressure than internal. 

Air travel, even in pressurized planes results in a lower  than ground level pressure.

Consequently, you should always remove user accessed O rings.

Worst case condition you could pop a non accessable ring out of it's seat.

#391467 Upgrading from D300

Posted by okuma on 20 January 2018 - 04:13 PM


We just took possession of two Nikon D500 cameras and Subal housings from Reef Photo

They were ordered in late November during the time of many comments about Subal's financial problems.

We did not experience any problems.

Each was equipped with the Subal TTL and flash triggers. Reef set up and dialed in the TTL units and they are spot on.

This was our fourth set of Subal housings from Reef.

We are still using our original ports and ordered the new housings with the type 3 housing ring.

We are also on our second upgrade of Vivid vacuum systems. As a supplier, Vivid is one of the best - ranks up there with Reef !

Regardless of which housing you go with, I strongly recommend the Vivid.

The best tool to use is called a "strap wrench"

It uses a plastic or reinforced rubber strap to go around the cylindrical object and is the least damaging tool to use for this application. Usually available in auto parts store. I carry one with me on all trips. Handel has been shortened for eae of use and packing.

#384996 Inon strobe - how is the water getting in?

Posted by okuma on 12 June 2017 - 07:02 PM

Change the battery cap!.

I had a flood due to a partial circumferential crack in the root of one of the threads. When looking at it in your hand it is invisible; but when screwed down it opens to admit small drops of water!

#384749 D7200/7100 - Focus mode and area underwater

Posted by okuma on 05 June 2017 - 07:21 PM

A personal choice; I always use single point, lock focus and recompose.

What brand housing are you looking at?  There are good, used top of the line housings available that you should not give up this feature.

Are there any other functions not available?

Good luck!

#374002 which brand(s) for reliable clamps

Posted by okuma on 26 May 2016 - 10:09 AM

I have some of the very first Ultra clamps - anodized blue!

Periodically do the following maintenance:

1. replace all the O rings

2. dis-assemble and wire brush off the screw.

3. add a small amount of o ring grease to the threads and enjoy your 'new' clamps!
