Keldan ask to send the torch for inspection as well since damage might occur also to the head. Battery is dead! And here come the question, should i send it or buy a new (Bigblue TL4800P LED dive light / tech light or analogous)? And making a comparison with my Weefine Solar Flare 13000 Lumen (i own the previous version of 12000 Lumen), what i see as a missing part is the vacuum valve that Weefine have. Maybe that has to be a standard (?) to high end lights and torches (even for tec dive) since that componet of equpment makes you to use is as mandatory step.

Just email them - i will see with an engineer if we can test the proprietary circuit, if is alive or not. Lesson learned ...

As the title says, if you don't check that the cap is tight at the battery area, then you will flood it.... The light (is the keldan torch) seems to be alive as i can understand that is sealed with resin from the battery area. And i have to fix the Keldan Battery 49 Wh Li-Ion. New cost nearly 400 euros, so any advice how to fix it will be great. As i understand, 4 18650 with a microcontroler and the changing are are what makes the battery pack. How to proceed?

We have done it for several missions and still use it. Small dome (4", 4"3) and hang the rig on the right d-ring with a double boltsnap. No covers, etc or tight the neoprene cover, otherwise you will loose it. You travel fine and when reach the target, you stop etc. SUEX has nowadays several solutions to be used and am on the doorstep to buy one.

Highly propable > https://projectseahorse.org/blooming-beauty-of-stratoni/. A bizzare colony exist there, with running activities by a local club.

In the Mediterranean Sea, to my experience, NEVER. And since i can guess the place of the image, which host a significant population, easily i can make series of such manipulated material ...

You talk about that? https://oceanographicmagazine.com/opa-winner/2021-cpoy-finalist-nicholas-samaras/ No revoke but several rumors on manipulation ...

Btw we need TELESIN type housings that are afforable to include extended battery packs for various applications (i.e, BRUVS for long time - these are baited video structures to monitor the fish diversity of a certain habitat). We have some (https://www.backscatter.com/Anglerfish-GoPro-HERO9-HERO10-HERO11-Underwater-Housing-with-Battery-Plate-AFCL-GP9-F570) but are way expensive in comparison to the TELESIN styles.

Thanks for the clues and approaches you follow! Am not that meticulus at all. Thats why i have Aquatics since 2012 (no service at the first). But since the company is in Canada and the European sector is nowadays small (and a bad experience from a Service Center) i decide to move to Nauticam (almost everywhere in Europe you can find a dealer). Amazing ergonomics, interesting building approach and lots of ports and adapters to use my Aquatica staff. No downside for that investment! The electric air blow is something that i have to use in Nauticam due to the lots of holes they have on the top (and to blow water from the buttons). Let see how far it will do!

Happy owner of Nauticam system (migration from Aquatica), the rings are more complex from what i was used (just bayonet system and thats it). Lock systems, zoom staff, lock mechanisms - all that have moving parts with orings and seals. How often do we need to service also that parts of the equipment?

An ex seagrass meadow, taken care by intensive and continuus anchorage of boats within a marine protected area and a dead noble shell. A combo of two emblematic species / habitat formers / ecological engineers that we loose day by day. Even if the seagrass meadows are abundant in Greece and elswhere, locally we have huge issues. The noble shell / fun mussel - we are among the last that we see it alive, abundant everywhere. Now only in two locations in Greece and the Sea of Marmara and few spots in Croatia. What we can do for that? Anchorage systems and ban of free anchorage is the way to go. For the fun mussel / the noble shell? Practically nothing ....

When i see the same images, i couldn;t believe it! How dramatic the same spot change, from colorful stars to muddy algae ..... And this timely aligned with a lecture i will give on NYU Abu Dhabi about "Seascapes under siege", where art is part of the way of awareness and shaking the society! That article is a nice review (scientific) > https://www.cambridge.org/core/services/aop-cambridge-core/content/view/6422D490CBDB30E9798D4D41AC20FA67/S2754720523000136a.pdf/the-role-of-art-in-coastal-and-marine-sustainability.pdf
