    How Cave Shops Calculate Cubic Feet

    Are Florida cave diving shops selling hot gas? I returned to Florida caves with my transmitters and being the numbers nerd I am I decided to take a little time at the end of the week to calculate my gas usage. I was wondering if the fill card I had on file was enough to cover my week of diving...

Orda Cave is the largest gypsum cave system in the world and the second longest cave in Eurasia. Because of the gypsum walls and no river inclusion the...

    Downloading Cochran Dives on your Android Phone or Tablet

    I've succeeded in getting Subsurface to download dives from my EMC-20H using my Android phone. It requires a typical OTG cable and the standard Cochran USB data cable. Now I can download dives and inspect profiles while still on the dive boat. To make things easier I've ordered an adapter to...

    More Open Source Cochran Utilities

    I've developed a set of tools to aid in creating libdivecomputer.org modules and Subsurface functions to read Cochran computers and log files. These tools can read Cochran dive computers, and read ANA, WAN and CAN files. These tools may not be of much use to non-computer savvy people but I hope...

    Hollis H-160 DPV Upgrade

    I purchased an H-160 years ago before I knew much about scooters and before I was tech certified. It always had trim problems, as if it were meant for sea water, and it had a run time of about 1h15. Three years ago I decided to upgrade it from NiMH cells to LiFePo4 cells that doubled the run...

    I'm working on software to access Cochran dive computer logs. The software is freely available and allows any dive logging software maker to read Cochrans. One good example is Subsurface. Currently the software supports EMC and some Commander models. What I need are older Cochran computers for...

    Anxiety Management

    I met Peter Murray at Peacock Spring last week and I thought I'd exercise my SB account and ask about managing anxiety. It was the same week in Peacock and at about the farthest penetration of my young cave diving career that I experienced anxiety. It was enough anxiety that my breathing...

    Neck seal replacement, gluing onto the neoprene's fabric side

    HI, I need to replace the latex neck seal on my son's Mares neoprene suit. And for the reasons below it would be easiest to glue the seal to the inside of the suit, except it's neoprene and the fabric covered side is inside. If I were to use contact cement on the fabric side of the suit would...

    H-160 Control Problem

    I have an H-160 that was working properly until the prop was jammed by a foreign object. It blew a fuse which I replaced and now it runs as soon as I connect the battery. I tested the reed switch and disconnected it from the electronics and it changed nothing. Any other ideas where to look...
