    Mk 16 vs Mk 17

    For some time I have been interested in the Mk17/G250V reg set. My LDS has a really nice price on the Mk16/G250V but I don't recall reading anything here on SB re: the Mk16 So, for a cold water diver, how does the Mk16 compare? Or, perhaps more to the point, what is the Mk16 good at? Richard

    SP A700 vs G250V

    OK, the subject is cold water regs (groan!). I'm pretty convinced I'll buy the Mk17 first stage. No question there. But, in looking at the SP lineup, I see that the A700 second stage is all metal whereas the G250V has a plastic housing (with metal components). OTOH, I see from the user...

    PRAM Freeflow

    When I used my PRAM in the pool a couple of months ago, it was perfect. Last Saturday when I used it again, it had a slight freeflow. I haven't checked the IP (although I have the gauge) but I was wondering if this is the kind of thing that is easy to adjust or should I just send it back to...

    LP vs HP Tanks

    No, I don't think I am trolling. I want to frame this question very carefully because I will never overfill a tank. That's the baseline for this question: Legal fills only! I have always thought that there was no purpose to LP tanks other than, perhaps, to accommodate double hose...

    PADI Peak Performance Buoyancy Question

    I was given a list of all PADI courses separated by age groups. It specifically lists Peak Performance Buoyancy as available for Jr Open Water Divers at age 10. I want my grandson to take PPB and Altitude in the very near future. PADI definitely lists Jr Open Water for the Altitude class on...

    DAN Oxygen Provider Course

    Three of us are thinking about taking the DAN Oxygen Provider course and, as it turns out, the local instructor is the fellow who taught my Nitrox course. So, any thoughts on the value of the course? Any prerequisites? We all have Rescue training but my First Aid/CPR is long expired...

    BC Hose Routing - For DW Mistral Diving

    I want to dive with my DW Mistral but I still want an octo (for my buddy) and power inflation for my wing. Wimp that I am... To that end, I bought both a 13 cf and 19 cf cylinder (seems Luxfer won't be making them anymore so I bought them both). At the present time all of my dives are quite...

    Wet Suit Questions

    Does anybody change down to a 5mm wetsuit for the summer months at Breakwater? The last time I was their (6/14), my 7/8mm AquaFX was just too much. The semi-dry thing seems pretty nice when the water is cold but when it's over 60 deg F, maybe it isn't that clever. Same question for the...

    PADI Altitude Diver Course Material

    What course material is available for the Altitude Diver program? I have searched around the usual Internet shops but I haven't found a thing. Diver's Supply has a bunch of PADI material but nothing for the PADI Altitude Diver course. All I want to do is buy the training material. Later on...

    Shorty For Pool

    Our pool is about 74F at the moment and in the heat of summer will get up to the mid 80s. I don't have much of a problem in the mid 80s but I want to get some bottom time earlier this year. Like this weekend. I am thinking about a 3/2mm Edge "Flex Tec" shorty: Edge Men's "FlexTec" 3/2mm...

    I finally got my PRAM wet

    I took my PRAM to Monterey (Breakwater) today and used it with an OxyCheq SS Travel Plate and a HOG 32# wing. It worked very well. I really like the zero effort breathing when I am laying on my back on top of the wing. Somewhat less than no effort... Thanks to all who have endured my...

    Dacor H-Valve HP Port

    Does the HP port on a Dacor J-Valve use a standard 3/8" HP hose fitting? If not, is there a source for some kind of adapter? Thanks! Richard

    Tank Valves, O-Rings and RAM

    I took my RAM to the pool today and before I could even get it wet, the Viton o-ring between the tank valve and the banjo fitting blew out. It's an 014 o-ring. I replaced it with a black (Buna-N?) o-ring and left off the banjo fitting. I blew that out with just the reg connected. I am...

    Easiest Way To Dive McAbee?

    We're thinking about diving McAbee tomorrow, 3/26. One reason this is our first attempt at McAbee is that the idea of parking across the street and humping the gear to the beach is somewhat daunting. Is it possible to use the El Torito parking lot? I don't care if it costs money and if...

    Horse Collar

    I finally got that Sea Elite Horse Collar (in black) from Divers-Supply.com Discounted prices on Sea Elite Horse Collar at Divers-Supply.com I bought a couple of CO2 cylinders for the backup system but I went ahead and plugged the hole with a regulator LP plug. I don't think I need the CO2...

    Carry Bag for DH Regs

    A silly question, I suppose, but how do people pack their DH regs for transport to a site? I know, wrap them in towels... I do that but I was wondering if there is a more professional approach. Maybe a particular regulator bag that tends to work well. Hopefully something I can just order...

    Omega II Max PSI

    I have downloaded a copy of the Oceanic Regulator Owner's Guide, Do. No. 12-2018. In this document, which includes the Omega II regulator, the maximum pressure for the yoke connection is stated to be 3500 psi (Page 12). I have several older Omega II regulators and I was wondering if this...

    Yoke Failures?

    Is there any evidence that would cause me to be concerned about using older yoke regulators on 3442 psi HP steel tanks? I have a bunch of old Oceanic Omega II regulators as well as some new yoke regs (Edge Epic, AquaLung Titan, Oceanic Delta4/FDX10 that I am using with HP 100s. Is there any...

    Regulator Service Training or...

    I want to learn to service only my regulators - Oceanic Omega IIs. All of the others will be sent out. So, how do I start? Sure, I know it's a dumb question and I did try the Search box but the results are even dumber... Are there classes I can take if I am NOT affiliated with an LDS? I...
