I've used this option on occasions but the vox is next to useless - even on some of our models that have variable vox sensitivity. The wind noise / coughing etc always defeats it. We use them with a push to talk button still active. that way you can make the decision whe you want the other person to hear you and when you want to swear at them under your breath.
I find the PMRs really useful when putting the boat on the trailer or even sending someone for chips !
If you want a duplex conversation then the motorcycle intercom sounds reasonable and at £20 is disposable when the water does get to it - which Im sure it will.
If you want reliable duplex comms then id have to say cost up for the real thing.
