MORE RESEARCH
Ive been researching the component of having a waterproof microphone came a cross several products. I came across neptune headsets which can be submersed
in water without any ill effects, as all cables and terminations are sealed.
Options include:
-
Military-approved earpieces fitted both sides
-
Alternative: one earpiece with other side vented for external sound
-
Waterproof microphone on flexible stainless steel boom
-
Alternative: Throat microphone
-
Heavy duty coiled cable fitted with non-latching waterproof plug (for fixed systems, allowing easy emergency disconnection)
-
PTT fitted to headset if required
NOw its about combining all of these researched factors into making a lifeguard radio whcih is retrofiited to VHFas most helmets use UHF. VHF can use channel 69 which is that national sls channel, speakers close to the ear to listen, a microphone for the talk back funtion, a function for two way talk.
