    Dive Computers: Conservative vs. Liberal

    Bob, Here are some links that did some testing on dive computers. UnderWater Bob ScubaDiving Magazine They both have some really good information. While the information is good, I don't particularly agree with some of their conclusions. Especially with some of the recommendations with...

    Bonaire electricity Question

    For electronic devices such as battery chargers including laptop chargers, you want to make sure they are "universal" or "worldwide" chargers. These types of devices don't use a simple transformer and can deal with any AC power source. These are the best type to have as you don't have to...

    new sealife reefmaster Mini

    That sounds like a bad CCD. That happend to my DC-500 when it locked up underwater and overheated before I could surface. I returned it back to sealife and they replaced it, at no cost to me. ---- bill

    OceanLog beta version 2.1.4 Available

    Not sure about Vista, but I've gotten that exact same error on XP with a 3rd party database package. If I enabled administrative privileges for the user it worked just fine. --- bill

    new sealife reefmaster Mini

    Does the mini have auto focus or is it a fixed focus lens? I was thinking that it was a fixed focus lens. --- bill

    Oceanic/Aeris comparison question

    A few things I've noticed. - The oceanic branded items seem to be slightly higher priced than the Aeris equivalent. (This might translate into better margins for LDS) Example, just look at the pricing of the download cable or compare the price of the Aeris AI vs the Datamax...

    Back Inflation Divers Can you do this?

    I dive a Zeagle Brigade. When weighted appropriately I can get into just about any position I need to get in for photography. However, what I have noticed is that sometimes after I'm in a head down position tilted to one side, remaining still, I will begin to rotate to the other side. What...

    Atmos 2 sample rate.

    The PC s/w doesn't work properly with depth based sampling. In depth based sampling samples are stored in dive computer when the depth changes the selected amount. When in this mode samples are not stored on regular and even time intervals. Each sample does have a timestamp on it but they...

    C4 eLED or C8 eLED Plus?

    What I find interesting is the C4/C8 (not the C8 plus) eled lights both have high & low brightness settings but it was never mentioned on the UK web page. Also, when I collected data about LED lights about a year ago, the UK WEB page was quite a bit different. Back then it listed the brightness...

    Orange BCD!

    For those who haven't seen the color in person, its not what I'd call a bright orange. Its more of a burnt orange. If you are a University of Texas fan, or know their color, thats the color it is. In other words its not a University of Tennessee or Safety orange its it little bit darker...

    Orange BCD!

    If I remember correctly, the Velcro is only normally used to release the weights. Normally, you use the zipper on top of the weight pocket to load/unload the weights so it saves wear on the Velcro. --- bill

    Pervasive Fallacy about Split Fins

    Pervasive Fallacy about Split Fins

    Now this is where I think some of the problem is. The above logic is flawed. Thrust can produce acceleration but acceleration is NOT equal to thrust. Acceleration is defined as: The rate at which an object's velocity changes with time. Thrust is defined as: A force that pushes an object...

    Pervasive Fallacy about Split Fins

    Its that #4 that causes the most heated debate: 4. Split fins offer more thrust than paddle fins while swimming. Here are my personal observations. When I was selecting gear a couple years ago, I spent an entire afternoon swimming in a pool and switching between splits and non slits...

    Aeris Atmos AI

    This could be due to your sampling rate. If the sample/profile data eats up into the sample memory used by previous dives, you will not be able to download them. The older s/w used to allow downloading dives if they didn't have dive profile data. The newer s/w doesn't seem to allow this. In...

    OceanLog beta version 2.1.4 Available

    Hmmm. Looks a bit off. ~factor of 300 Doug should be able to help you out with this one. Well, If I had to guess, I'd guess that the s/w is dividing by a fixed constant internal "working pressure". The s/w did this (at least in Imperial mode) before the working pressure field was added in the...

    OceanLog beta version 2.1.4 Available

    My guess on the SAC rate issue: Since metric tanks aren't normally rated like imperial in terms of volume and working pressure, I believe that the working pressure for Metric should always be 1 BAR. This is because the cylinder sizes for metric are an empty volume or the amount of fluid...

    Gekko or Aeris XR-2

    Just a little information on Air integration. The Air Integrated computers also will calculate an "Air Time remaining". The computer will look at the remaining pressure, your current breathing rate, and depth and will calculate how much time you have until you need to start ascending. Some...
