    You fixed someone's Optima? Since they haven't even shipped yet, I find that hard to believe...

    There are Optima's out there but they are prototype versions, and I believe the first of production units will be shipped soon. I've recently seen one and I have to say they are very well built. Every RB is going to have its ups and downs, even the Meg. Sorry Ron but I have to say that I don't agree with you a this one because the Optima in my opinion has a lot going for it.

    one can dive at 80 fsw for 2 hours at a 1.2 setpoint and only accumulate10-15 minutes of deco time, however if one has to bailout to OC your deco obligation can increase significantly. I make a habit of switching my dive computer over to OC while in deco to get it in my brain whats going to happen if I have to bailout. (and then switch back, of course) Part of your deco procedures training on CCR must be a full bailout and deco on OC, managing your loop expansion and deco while off the loop.

    part of your bailout calculations must include horizontal swimming at depth if you are doing overhead enviroment or a dive which requires you to come back up the same line you went down (which is the procedure on BC wrecks due to current)

    see ya in the cold clear waters of canada!!!

    I have a couple spots open for a dive trip on these wrecks November 25,26 and 27th, email me at ron@tmishop.com for more details

    The optima looks like a good option to me.. My only real concern at the moment is the scrubber untl some data is published..

    The Optima has superior electronics to the Meg at this point.. All the recent upgrades to the elctronics are quite impressive.. The switches are now totally sealed and adition sealing is done on the battery compartment and kept out of the head.. I would still like to see a bigger display added...


    Most of the wiring is sealed.. the only part that can have an issue is the sensor harness which goes from the banana block in the head to the cells and that can be swapped out in under a minute...

    The adv looks quite well designed and the lungs look like they will dive well.. The DSV is basic, I'd like to see the inside of it.. I don't like the idea that the megs DSV doest use orings to seal the loop but rather machined surfaces, although its machined quite well..


    The megs T -pieces are more robust, but I dont see an issue with the ones on the optima...

    I do have a complaint about the color coding of the hoses, in my mind a big scre up, the have the inhale hsoe signaled with a RED ring.. everyone else who uses red,means its expelled gas.. If they didn;t want to introduce another color it should have been put on the exhale t...
