    For Sale "Titanium" backplate and STA from AliExpress, $50

    I bought one of the Ali Express titanium backplates. Quality was decent. I took a torch to it to see if it was really titanium, and it changed colors as expected. Titanium being less dense than steel meant I needed more lead when I dived it. It seems like it would be a decent backplate for...

Based on the science both organizations...

    DEMA Blacktip new version

    Actually, the whole point of open source is everyone can contribute new features and capabilities, as well as fix any bugs they find, then the original manufacturer CAN review the code, fix anything they don't like, and roll it into a manufacturer supported upgrade such that everyone benefits...

    DEMA Blacktip new version

    Yeah, but after their prior behavior, I don't think anyone wants to go through the hassle of making improvements. The open source Blacktip discussion was not treated well by Dive-X

    DEMA Blacktip new version

    I can't figure out if they copied the slow speed migrate from the modified open source firmware. That's turned out to be the most useful feature. No surprise Dive-X took so much offense modifying their open source firmware in our Blacktips, now Dive-X takes those new features and uses them for...

    Nitrox fills in So Cal?

    In2Deep in Santa Monica. I think Zen in Pasadena does premixed nitrox as well

    Atomic Scuba Heat. Does anyone else say WTF?

    I have one, and dive with it regularly in So Cal. When I first got it, I put it on late fall, took it off in the spring when the water warmed up. Then I just left it on. I notice I don't get nearly as cold as my buddies, and doing a side by side comparison of second stages with and without...

    For Sale "Titanium" backplate and STA from AliExpress, $50

    I saw the titanium backplates on Aliexpress. How is the quality on these things? Did you ever sell it? I'm going to be in San Jose around Easter, so could look at it that weekend and pay with cash if you still have it, so no PayPal or shipping

    Aquaprop L DPV what are your thoughts

    If you want one any time soon, the SubGravity web site is showing 10-12 week backorder for the Aquaprop L. I assume that means they need to make another production run and then ship it from Germany

    blacktip > is the warranty any good ?

    I got an early Blacktip, like serial number less than 150. Quite a few of us went in on a group buy when they first came out. On the second dive my scooter stuttered and died. I exchanged some messages with Ciara, sent it in, they redid the reed switch (they changed the way they aligned things)...

    Unexpected sighting

    Early Saturday afternoon with dive buddy Scott. I was pressed for time, so opted for a local dive and we dive the pinnacles off of Malibu Rd. Sometimes it's better to be lucky than good, and today we descended right on one of the pinnacles, with amazingly good viz (roughly 25 ft), despite a...

    Divex Blacktip cruise handle

    The updated firmware with cruise control has been rock solid. And nothing mechanical to get stuck with cruise control

    Blacktip firmware modifications

    Excellent news! I really appreciate all the enhancements from your updated firmware. The viz can be really crappy where I live, so the slow speed migrate feature is really intuitively obvious. I don't understand why Dive-X didn't implement it that way to begin with. As far as cruise control...

    First Steel Tank - Single LP85 or HP80

    HP 80 and LP 85 are very different tanks. LP 85 is about 1.5" taller than a HP 100, so nearly the same gas volume at the same pressure, which makes a difference if you have trouble getting a good HP 3442 PSI fill. Also, HP 80 are especially sensitive to getting hot while filling, so if you want...

    Blacktip firmware modifications

    If your serial number is above a certain number, you can only use the newest Dive-X firmware or you could brick your Blacktip

    Blacktip firmware modifications

    Unfortunately, they seem to have removed most of the content related to firmware. Possibly because several Blacktip owners bricked their scooters. Please report back if they are helpful when it comes to firmware. And, yes, 1.18 seems to be more reliable than 1.15 for many, turning safe start...
