Why I don't cave dive (+link to BBC article)

09 May 2016 - 12:08 PM

This adventure and the movie made from it explains in great detail why I have no desire to do any cave diving!




These guys live on a different planet to the one I inhabit LOL



Light & Motion: really bad service

01 September 2015 - 03:29 PM

I have two Sola 4000 lights which were giving decreasing burn times.


I e-mailed Light & Motion (L&M) asking about replacement batteries and was told the Sola 4000 lights are obsolete and no more batteries or printed circuit boards are available.


They then offered a trade-in against their new 8000 lumen light. I asked if I could trade both 4000s on one 8000 and was told OK you can do that, so I shipped the lights, chargers and filters to them.


When my lights arrived at L&M I got a phone call saying they would not trade two lights against one - a major disappointment; they would see what they could do about repairing the 4000s at no charge. So I said if you can't do the trade you promised, I need the 4000s back by next Saturday the 22nd to take on a dive trip. They shipped the lights on the 14th as near as I can tell from their e-mails. The 4000s arrived two days after I left town, on the 24th.


These are at least two really unnerving "don't care" or "can't figure out how to do customer service" errors stacked together. In addition, every time I replied to an e-mail, I received back their trade-in letter in triplicate, sometimes addressed to me, most times to someone else; a heavy confusion factor from what seems to be a broken web site.


Since I had similar problems last year with faulty service on housings, I quit. No more L&M for me. I started with their Stingray housing in the 90s, so this isn't a short-term decision.


Had to be said.


End of rant.



Sony AX100 autofocus problem

22 June 2015 - 05:01 AM

Sometimes when I am using autofocus with the Sony FDR-AX100 and a flat port on the Gates housing, autofocus doesn't work!


When looking at the clips after the dive, the subject can occupy 1/3 of the screen, and be nicely centered, and it is out of focus; the background is in focus even if it is relatively far away! The contrast seems to be sufficient; the camera apparently does not respond.


This seems to have happened after the latest firmware update to V3.0.


There seems to be more focus "hunting" underwater since the update. Topside, the problem does not seem to happen...


Anyone have any thoughts about this?


All help appreciated,



4K screen capture -> nudibranch eggs

25 May 2015 - 04:19 AM

Here's a screen capture of nudis and their eggs from the Blue Heron Bridge, Phil Foster State Park, Riviera Beach, Florida USA:

Attached File  F.-D.EDIT.jpg   157.42KB   21 downloads


The Nudibranchs are Flabellina Dushia (thanks to Anne D. for the ID!) and are about 5/8" (1.6cm) in length.


I used the new ReefNet diopter adapter and a +10 SubSee diopter on the Gates AX100 housing. The Sony AX100 has firmware v3.


The tiny spiral of eggs is clearly visible, making the individual sand grains look like large boulders!


Ask me if I'm sold on 4K LOL




PS: The (absolutely horrible)  video is on Youtube at https://youtu.be/1NtMt7f0CjU I will get better, I promise - it was my first try at using a diopter...
