Thanks both - wasn't sure if it was a distance thing for the focus, or a physical fitting thing. Sounds like it's the latter so will be easy to test quickly on land. Thanks!

I think it's good that they're trying to do something to help protect the reefs......its going to be tricky to get a balance though! I wonder if there could be places that would insist on a photography "certification" in the future - it's going to be hard to police either way.

Does anyone know whether you would need the M67 adaptor/spacer when using a non Nauticam wet lens? I've got an inon UCL-165 so it's got the M67 thread, but I'm not sure what the spacer is for that comes with the SMC-1 for (as I don't have the lens or spacer) - would it be needed for all diopters or just the Nauticam specific ones? Cheers!

I just tried it on "Continuous Low" (A7RV so I'm guessing 3fps?) and I'd say every other shot triggered it so 0.9s seems more correct than 6s Still haven't got round to 3d printing anything but I might try a cardboard prototype - it will literally just be something angled upwards with aluminium foil on anyway - maybe I'll go full MacGyver and just Blu tac it on 😂 It's not like I intend to actually use it anyway, it's just in case the trigger has issues!

Yeah, I was looking at the IM20 initially but then found this one which looked smaller (was concerned about the height mostly) so went with that one: 34L x 18H x 29W https://www.aliexpress.com/item/1005008042088749.html It's not adjustable in any way, so you can't reduce power to save battery or anything though.

Just putting this out there to see if anyone is selling an OS-1 Snoot, ideally in Australia but happy to pay shipping if it makes sense! Not too fussed for the colour slides accessories, but the aperture cards would be good 😊 Cheers

It fits easily in the NA-A7RV housing, it's not much bigger than the TRT trigger. It doesn't line up with the holes to trigger it straight away, but just putting my finger in front of it bounced it off enough to trigger my MF-2 so I'll see if I can 3d print something and stick foil to it - which is pretty much what my seafrogs housing seems to use to bounce the light to the fibre ports. There's a slant at the front of the flash which could be a good place to put something simple on. It's never going to do anything fancy but it could be a cheap backup option at around $55 AUD.

I know this is an old thread, but for some reason I have it in my head that the thread on the seafrogs housing is M10x0.75 - which is a weird one. I was looking for an adaptor for ages so I could figure out where the leak was on my spare housing but never found one. I did get a die to cut the thread but never actually got round to doing anything with it as my "main" housing was fine and I'm no metalworker! If you know a machinist, or ask some machine shops, maybe you could get an adaptor made up so it fits a more standard threaded vacuum system?

There isn't quite as much space in the A7RV compared to the 6700 but I found a smaller looking flash, the MedaLight F1S, so I ordered one to try out - will report back if it fits!

I've used an x-adventurer M1000-WRA, it works well for the auto off feature which works with both the white and red light. Takes an 18650 battery, claims 90min for the white light at 1000lm but I haven't had it run flat yet as I've always swapped the battery out before it runs down to 0

Hey all, This isn't really a DIY thing but I was wondering whether anyone thought there could be a chance of one of these mini flashes working as a strobe trigger (if it fits in a housing obviously)? https://www.godox.com/product-a/iM20-iM22.html To clarify, I'm not planning on actually doing this, just thinking it could be a potential cheap "emergency backup" option for if my TRT trigger breaks on a trip 😁

I imagine it's the older 32203, I just got one for my A7RV nauticam housing and it fits, but you will probably need to set the viewfinder to "zoom out" - is that an option on the a7riv too?

Looks like it's 6.9kg on land and 1.8kg in the water so I'd better have a look at what combination I'll need to get! I left my wet lens and focus light off so 1.8kg of lift should leave it slightly negative I think. Maybe some of those fixed buoyancy carbon fibre arms for the bulk of it plus some removable floats for smaller adjustment if needed. I did see a stix belt for macro ports that could be a good way to add the floats without having all the arms covered in them. I've got a couple of Hyperion floats that total 0.8kg so I could use those too: https://www.onlinedivegear.com.au/products/hyperion-float-tube-set-large?variant=17897469706329

Thanks everyone, I'll get the luggage scale out and go from there. Those adjustable buoys look like they'd be great for someone who changes the rig often. I was briefly looking at the adjustable arms from weefine but wasn't sure about them - they're relatively expensive and I'm assuming any kind of small leak would make them pretty useless for buoyancy. I might get some stix or similar floats that just attach to the arms, that way it can be adjusted if I change ports down the line, and if I'm settled with a specific setup later I could swap to the floating arms or something. Thanks again!

Hi everyone, Just wondering if there's any resources for relatively common gear so I can get some kind of starting point for floats etc? Not sure if it's an exact science or individual to preferences and equipment. I've got the Nauticam A7RV housing, and will have 2 backscatter MF-2's, 4 cheap 6in arms (might swap them for floaty arms), and the 90mm macro port (think it's called the 105). I'm hoping someone out there might have a similar setup and might be able to give a pointer as to roughly how much buoyancy may be needed? Or does it vary enough that you just have to do trial and error, or weigh it in a big bucket? Thanks!
