I’ve just got my PT015 housing back from her first service (it’s only been 3½ years!) – some of the buttons were sticking a bit. I still really like the Oly, so if I can keep using her for another couple of trips, that’d be nice.
So here’s a thank-you to Kevin from AquaPhot.
Kevin’s given me really helpful advice in the past, sourcing my D2000 and lots of other bits & pieces.

… Not really a “twin”
The last piece of the jigsaw was an Inon Z240 strobe from Ocean Optics.
The controls and modes are – not surprisingly – very similar to the D2000, but (as well as a bit more power)the Z240 has a “hard-wire” connector if I go SLR, and the pre-flash magnet can be switched in-dive (this has to be unscrewed on the D2000).
ULCS arms and clamps completed the setup.

OK, so the housing needed a couple of screws from Ikelite.
Cameras Underwater sourced those for me.

Mark J. from my club made up a tray for me, which was ideal. Big Thanks, Mark. A couple of “Oceanic Fit” shoes, and it was compatible with my 10-Bar tray for the C5050Z. This meant I could switch cameras between dives, which is really handy.
