I am being treated fairly by my LDS. No question there. Please keep in mind that this is life support equipment and I am expecting a higher standard of quality than what I got. When a company purchases others, they are branding themselves into the new acquisition. The transmitter issue may simply be a batter gone bad early. Who knows? The BC is a complete disappointment for the cost and the hype that came with the marketing.
I have almost the same setup Black Diamond, Vytec DS with a D9 and Black Perl reg and I haven't had a problem with any of them and I have years of diving with them.
They way you have made your assumption we can make our assumption that you we not taking proper care of you equipment since that has happened to you. And Aqualung does not make the batteries they buy them.
They way you should have phased your question in the beginning is has anybody else had this problem and went from their.
And if one little equipment malfunction will cause you to die maybe you need better training.
Agree with Dave, Jax, etal. High quality, great customer service.
