Backscatter OS-1 Snoot caddy uploaded to Sketchfab: https://skfb.ly/pDRKG. I've added some splines on the Mini-Flash end which match nicely with the features on the MF, it's a snug fit, but it doesn't rotate around the MF.

I currently have a small bolt snap on the OS-1, but thought a mount clip would potentially work as mine is usually off by default. The example on Printables has the aperture slides; nice touch. Always takes about 3 to 4 iterations to get these things right, if not more!

Has anyone made a caddy clip for the Backscatter Mini Flashes to OS-1? If not, looks like I'm off to another project.

Adding to the MFO-3 posts, I had a chance to try the lens with my A7C and 90mm macro in our wonderful Puget Sound Seattle water yesterday AM. The rock fish pics are with the MFO-3 and without, from about the same distance from the fish. The Sea Angel was just flapping in the water column and is about a centimeter in length, so approximates a lot of the Hawaiian blackwater critters. For blackwater, I think this provides a very nice solution from what I'm seeing. Storing the lens is a little more difficult than the smaller CNC diopters and I usually use the bayonet mount. I can see why a flip holder is going to work out a better! There was also negligible weighting issues with that lens being so far out in front. Only one dive so far, but this looks like a great lens. .

Do you use the nauticam with that setup or would those lenses fit with the ikelite? Because the 28-60 does seem to fit a lot of criteria in that case. Yes, I'm using the Nauticam NA-7AC housing.

Just my 2-cents as well, from experience on the 7AC for about 3 years,. I suspect I'm due for an upgrade when I can throw the $$$ at new body and housing. I've found there's basically three different configurations I use: 1) General scenarios: The kit 28-60mm is a nice lens underwater and gives a lot of flexibility. I normally use the WWL-1B for wider shots and carry the CNC-1 on a caddy for instant macro (even swapping in water with dry gloves). This has really served well and provides versatility for anything from a nudibranch to manta on a single dive. 2) Macro: I also used the Sony 50mm for a couple dives and it was a dog! AF is just incredibility slow. I have an adapted Nikon 60mm and it's a better. My general macro is the trusted Sony 90mm and I recently added an MFO-3 for blackwater and some of the bigger critters. I haven't tried the Sony100mm but keeping an eye on it, but could entail a new port. As such, so far everything is using the same port for macro. 3) Finally, dedicated wide angle: I have the adapted Canon 8-15mm fisheye and really like it, and use it with a Zen DP100. Great for CFWA, but I need to get a larger dome for sharper wide angle as the corners are soft with the smaller dome. The main issue with the 8-15mm and the 7AC housing, due to the OEM zoom that resides on teh port adapter, you had to install camera into housing/adapter port, then install lens, and finally, install dome. I created a printable zoom gear that lets me extract the camera/lens at as one unit, and uses the housing zoom gear rather than the port zoom gear.

We've looked into running object detect and identification models at the edge (on-device with smaller hardware) and the biggest issue ends up being compute and storage. Most models today run on GPUs, thus the massive data centers and the associated run-up in nVidia stock! We've been able to run some of the smaller models on-device, but without cloud connectivity, something like a species identification model may be a bit too far for current hardware. You may get something that will identify at a larger level (whale, shark, porpoise, etc), but granular ID could be tough.

Very cool Peter! I think we did Verde Island the day before your group went over.

Found this shrimp in the finger coral at Koloko outside Honokohau Harbor, Kailua-Kona, HI. Any help on this one? Resolution reduction lost hair detail on the front claws.

Really great video Peter! I see you got a manta fly-by as well, we weren't so lucky.

Ha! Yes, we most likely did as I was with the Silent World group! Looking forward to your videos! Being a fan of macro and muck-diving (living in Seattle), I thought Dumaguete had the better assortment of critters for sure.

Had a great trip to both Puerto Galera and Dumaguete this month with about 4 days in PG and another 3 in Dumaguete. Stayed at Atlantis Resorts for both locations, which was very nice with great staff. With half-moon phases, currents were minimal and visibility good. Everyone has their likings, but I can say the muck diving at Dumaguete was a favorite with a good variation in muck and reefs, as well as a trip to Apo Island. Also did a side trip to Oslob for the whale shark snorkeling, a bit of a tourist circus but the locals have figured out how to convert fishing revenue to tourist income. I'll spare the pretty reef and common nudi pics, but there's a great variety from the rice-grain Shaun-the-Sheep up to the larger varieties. Equipment was Sony A7C, 28-60mm/WWL-1B/CMC-1, or 90mm macro, or with the whale sharks, Cannon 8-15/Zen D100 dome (natural lighting).

Do you have the extension on the release tab? That makes it significantly easier with dry gloves.

Earlier this year, had a nice trip and stayed at Volivoli, about 2 hours from airport via van. Not really much of a house reef, but you can get the dives in for sure. Some of my pics were posted to this thread: https://waterpixels.net/forums/topic/2386-fiji-volivoli-may-2025/

This is a link for Github .stl file, GitHub - CaliforniaCurrentsPhoto/snoot-adapter-BackScatter-to-Sea-and-Sea for an adapter from the YS-D3 snoot, to the Backscatter Optical Snoot if you have a YS-D3 and don't want to use th3 MF-2.
