    Tesla Releases Details of its 6,000 mAH 2170 Battery

    Based on the form factor 21mm diameter, 70mm length I would assume it has not been used in most scuba products. Most lights and and light battery packs are 18650 cells. The xccr also uses 18650s. Computers like the shearwaters use 14500(AA) size batteries. Looks like it could be a good option...

    Is this site still alive?

    I think FaceBook has taken a big toll on all the boards like this one. That said it is alive, and it has a facebook page that is much more active.

    Use of images without my permission

    Hey Don, In my personal opinion from your stand point I would let it go. They are reselling the product they bought from you after all. However if I was in the market for a used Don6 stand I would not buy from them because the photos don't show the condition of what they are selling. But hey...

    Gurgling at the exhaust T-Piece

    Well Brad you actually got my interest with one of your post, but there is no picture or description of what of the part when you follow the link. So, what is it, does it replace a standard dump valve or do you need a counter-lung with the correct flange?

    CCR Fatality in Cyprus

    Very said news. Hypoxia has always frightened me on shallow dives, which I have done often with my son. I understand we do not know if this was hypoxia. But for me when I do a dive in the 20 foot(6 meter) range I have a very specific procedure. I make sure that my ADV is off, I flush my loop...

    JJ vs X-CCR

    I have been diving the X-CCR for a while and I have the upgraded Shearwater electronics. I have not had any issues and have found it to be have much better trim and work of breathing then my previous CCR, (AP, not a JJ). I have not had the opportunity to dive the JJ. Obliviously the electronics...

    I'm not sure what you not being a fan of carbon fiber has to do with anything, but why are you not a fan?

    Checklist App

    What you are looking for looks simple enough. I did take a look at Trello. Looks like it is more of an all things to all people then what you want. I'll see if I can get something together in the next week or 2 that is more diving specific.

    For Sale SubGravity Defender

    Don Interesting feed back. I would say that I have seen some interesting "features" in the menus, particularly when it comes to switching from the metric settings. Also I found my first couple scrubbers to be much like concrete. I talked to some of the Hammerhead divers I dive with about this...

    XCCR Vs Defender

    I dive the XCCR and I have 2 dive buddies with Defenders. From a work of breathing and a mechanical stand point they are exactly the same. Where they differ is in the electronics. The defender has all of the electronics in the handset. The XCCR has the power for the solenoid and on the one I...
