Does anyone have a recent report on the condition of Arena Rock (off Pt. Arena in N. California). Specifically, has it been hit hard by urchins?

Any reports from today for Pt. Lobos or Carmel area? I'm planning to dive Lobos tomorrow, but it sounds like it's been mucky.

I dove for years with a neoprene drysuit, backplate and no BC. You need a little gas in the suit, but it's easy to manipulate, making level trim a trivial skill. I ran with a crowd that all dove this way, didn't use an octopus, clipped the SPG right at the plate on the waist belt. Depth...

I dove my own boat and a lot of others for a while, including hard jobs removing barnacles down to just getting the slime off of race boats. I never bothered with a suction cup or lines and seemed to do just fine without. I'd suggest just hopping in and seeing how it goes before spending time...

Thanks Rob. I watch those links and also various webcams, but a first-hand account is always better. Sometimes people report diveable conditions even when they look bad to me online. It looks okay now and hopefully will hold at least through tomorrow morning.

Has anyone tried Pt. Lobos this week? I'm scheduled to dive there on Thursday and wondering what conditions have been observed.

There’s an “island” called Roca Partida in the Revillagigedos (S. of Baja), that’s a pinnacle in open ocean with steep walls. Due to the swell, the Avon tender couldn’t get close to the wall, which meant swimming in open water between the boat and the rock. We’d seen an oceanic white tip, a...

If you're starting with the Atomic swivel end on the LP hose, there's also a jam nut that goes between the hose end and the second stage. A standard hose will still work without the jam nut if you can't find one.

This is interesting to me. I've just started using a DIR configuration after a long time in a neoprene drysuit and a stripped down rig (single tank, no BC, no octopus, all instruments and knife mounted on a forearm unit, nothing dangling anywhere). I'm committed to learning how to use the DIR...

DDM: Do ventricular volumes increase due to immersion independent of exertion? Or, is exertion correlated with immersion -- and exertion is the root cause? If an individual with pericarditis tolerates exercise (of relevant duration and intensity) well, would you still suggest that they...

I have a set of Dive Rite for sale, size L, black, with spring straps. Used twice in the pool, never in ocean but I'll let them go for a good price. I went to a heavier fin for my set up, but the kicking was nice with the Dive Rite. Send DM if interested.

Eric, Thanks for the info. I'm in Santa Rosa and was looking for a close site, but that one doesn't sound great -- probably it's worth a little extra driving to get up to Stillwater or Gerstle. I have a (seaworthy) little boat, so I was thinking I might find something on the south side of the...

I've found some old posts about diving Bodega Bay breakwalls from shore on the Doran beach side. Does anyone know how it is on the west side, or if there are other sites on the south side of Bodega Head? I'm assuming boat entry for anything on the west side of the harbor mouth, and that comments...

This would be a great way to get up to speed before diving more independently. University diving courses are more similar to what you want than a dive shop course, but they're still quarter- or semester-length. There are also concierge instructors that facilitate equipment selection, travel...

My GUE-F instructor was agnostic on equipment brands generally, but he did think the Halcyon SMB was the best. You need to be able to inflate it orally, though I think the version with the LP quick-connect fitting can also be inflated orally. The SMB should have an overpressure valve. Another...

The only reason I can see to have the LP hose on an O2 reg would be to use the RescuEAN pod. A dedicated system for first aid is an extra device to maintain, but I think it's the best solution. It's somewhat surprising that DAN doesn't offer a DIN version as an option in a kit without a cylinder.

Thanks everyone. This was helpful. The EANpod can be found with Google for "RescuEAN" for those who are interested. The DIN medical regulator like Tursiops set up is what I was envisioning. Both are interesting solutions that are in line with my goal of using a O2-clean dive cylinder.

I don't think I'm looking at the right device and I'm not sure what to search for on the site. What you're describing sounds like the right solution. If I understand right, the set-up would be a standard O2 scuba regulator with second stage and a drysuit inflation hose. On the end of the...

The DIN O2 dive regulator is one solution, but it is not compatible with an oronasal mask or ventilator mask with MTV (should be supplied at 50 psi). The scuba first stage intermediate pressure is too high for the oronasal mask w/demand valve.

Does anyone know if the Multifunction Regulators sold with DAN Oxygen units can be converted to work with a DIN valve? It would involve removal of the yoke or CGA-540 fitting from the regulator body, and replacement with a male DIN fitting. DIN fittings with 1/4" NPTM are common. If anybody...
