Can anyone recommend a VHF waterproof handset that will take a standard earpiece. By standard earpiece I mean something like you would use in an average MP3 player. I know the earpiece wouldn't be waterproof then. But hopefully the handset would remain waterproof in an emergency situation, so you could discard the earpiece then and use the handset on its own if the worst came to the worst.
Ive used the external speaker connection from the navman 7100 and linked it to a twin jack plug on the dash, I can then plug in two sets of earphones, to listen in while under way, works a treat.
The female jack is on the back of the navman radio, so inside the console,
ive used a male female 3.5mm jack lead, and fixed the female end through the console, can now here all broadcasts whatever, just see it under radio
Unsure about using a non waterproof earpiece. Should it short out due to flooding then it could well take the audio output stage of the radio with it
For me it would be a non starter.
