    Lake Phoenix this Saturday?

    Fun time! Thanks Captain Sinbad and good chatting with you again! Minimum temp was 47 degrees. Wasn't too bad except for my hands when I took my gloves off for dexterity in removing fin. Then it became apparent. Viz was pretty good, but would have been better if we went to sunny area. 1...

    Lake Phoenix this Saturday?

    I think I am going to attempt a Lake Phoenix dive (or two?) Saturday. I have drysuit and all that, but haven't been in water that cold in a while. But with ambient air temps so low, maybe the water will feel warm? Figure it's worth a try at least. I have the fleece undergarment it came with...

    Anyone ever make Shearwater Silicone Cases?

    I see these Silicone cases sold by US vendors for crazy high prices. Then I see them on Aliexpress for $3 or whatever but only for Perdix AI. I have the Hollis (Petrel 2) and being tethered to CCR it tends to get banged around a lot. Videos on youtube of making silicone phone cases look pretty...

    Reading Wireless Air Transmitter using Arduino

    Interesting pics from the FCC system on the new boards. I can see two TI chips, then probably a MCU. I can't quite make out part numbers, but assume it's all software synthesized. Good job on capturing the output. My ham radio didn't succeed, but maybe I will try a wire loop like you all have...

    Frederick MD area divers

    Northern Virginia here... Juturna Springs was open for a few short bits before they hit permit issues or whatever. They have been working on it for years now. Those regulations seem odd. "No dives deeper than 100’ unless diver uses a standard technical diving configuration approved by the...

    Oh snap! Was just there Saturday. It was pretty nice day. Did not hit the bottom, made it to 55ft for a very brief period :-)

    Hollis Prism 2 electronics in head. Photos!

    Ah! Well if it's the wiring harness on the scrubber side, I believe that is replaced as part of the "annual" service kit. Not vouching for this vendor at all, but I can see the cable in the pic: https://www.rebreathersuk.com/hollis-prism-2-annual-service-kit-220-9010-revision-5

    Hollis Prism 2 electronics in head. Photos!

    Hello, in my case I narrowed out the o2 sensor by swapping them around. I figured it shouldn't be my harness because it was just 6 wires and 4 connectors. And mine was very clean! It's been a while, but I did take and put deoxit on a qtip and carefully clean some of the contacts. But if I...

    Dive Rite RG1205 parts no longer available, is there a "cross reference"?

    I saw the kits they had, but assumed the DR1205 is different than the DR1208, otherwise DR would sell the DR1208 kit as a maint kit for the DR1205? Figure when it comes time to replace I will probably replace the DR with DGX Gears D6 stuff. Friend just ordered a set, I will check out his. But...

    Dive Rite RG1205 parts no longer available, is there a "cross reference"?

    Yea I saw that. But I was wondering if regulators in general have a lot of re-label product that technically uses the same service kits. Since it's all made in the same factories. Virginia Scuba is handling it, and I told them for this go around it's cool if they source whatever. But then I...

    Dive Rite RG1205 parts no longer available, is there a "cross reference"?

    Was told by my local shop that the Dive Rite RG1205 regulator service parts are no longer available. I assume most of these branded units are made in China and may share internal design across brands? How true is this? Is there a cross reference of service kits?

    any scuba "yard sales" in the NOVA area?

    There are still some dive clubs! Here in Northern Virginia/DC/MD there is one via Meetup.com that is shop independent: Washington Area Scuba Club: A DC/VA/MD Scuba Meetup Group (Washington, DC) I think Virginia Scuba has a club at their shop as well. The yearly swap meet sounds cool. It is...

    any scuba "yard sales" in the NOVA area?

    Hello! I haven't seen anything like that from the shops up here. When I lived in Virginia Beach/Norfolk LDC would do them once in a while but I think it was the shop selling their excess not open to the public to sell stuff. Been a long time. I would think the shops don't like used market...

    Closed Circuit O2 Rebreathers and Training?

    That is a whole lot of courses that for the most part still won't cover what is in the 15 page manual that comes with the C96 says about how to build and dive it :-) If OP is competent at reading he could use the US Navy diving manual, O2 CCR section. The PDF is free, not behind a paywall and...

    Closed Circuit O2 Rebreathers and Training?

    @Angelo Farina Much thanks for the info! It's like Antiques Roadshow Scuba edition! I never dive the unit past 20ft, and I do purge the loop a few times first. Also, I do air breaks as you describe (I think I read about them in Mastering Rebreathers or from the NOAA/US Navy manuals) but will...

    Closed Circuit O2 Rebreathers and Training?

    Hello! Backstory -------------- Sooo. I actually have a Castoro C96 from O.M.G. in Italy, which I think is the unit you are talking about. I saw it years ago on RebreatherWorld.com, thought it looked cool and had an ebay search. I will post pictures of it this evening. Similar to the LAR V...
