Helmet Comms set options
We are about to replace our umbilicals, so it is logical that we also look at helmet comms options at the same time. Besides the Kirby Morgan offering for 4 wire comms, are there any other 4 wire sets out there?

Amron International, Ocean Technology, 4 wire comms is just you separate the mic. from the ear phones.
two wires for mic. two for earphones. then you have open circuit comms no need for press to talk it is easy. you need shielded wires. and a comm box that has separate connections for mic and earphones.
check out Amron or Ocean Tech and you can see how it works.
eliminates the tender b*******ing with the press to talk down and your having a pipe set on top of you.
It is a good way to go. A 4 pin Marsh Marine set up is perfect for hat and hose. top side separate banana plugs . I was using 4 wire comms before Kirby Morgan was in business in standard gear. It's not rocket science.
