David and John,
I will start charging batteries and filling air tanks and will test asap as the lakes are ice free now and David's comms system is on its way.
Kyle
Jon,
It has been a very long road to get to the point where some of these are going to actually be deployed aboard submarines. Now that these will be submarine mounted, the members themselves will run them thru the real paces we need and we will find the true limitations of such a communications system.
This was designed and built not to outdo anything already on the market, but to simply be a cheaper alternative to those not diving quite so deep and a bit closer to shore.
I really meant to say in my earlier statement was that if this works well in salt water also, 35' in depth would be a great first attempt at using them in a multiple transmitter environment. Deeper results will be had once more dives are performed with them aboard.
I have done my best...I am now going to rest a while and await results good or bad.
