Not if they unconscious. Handhelds are too big and cumbersome to be carried all the time. Done it for years and it is PITA. Simplest method is lanyard looped over one shoulder across the back of the neck with the radio
hanging near your chin on the other side. But still a PITA.
I know how DSC
works. Interrogating the HH requires possibly the only other crew on board to leave the search and operate the radio
. I prefer the hands free that AIS
gives me. I can select the target and then have range, bearing TCPA etc. on screen
It also will not raise an alarm
unless the cass makes a call. Big plus in favour of the AIS
I see where you are coming from but still prefer the AIS solution.
Yours is probably cheaper if you already have DSC, but requires more intervention. 2-way communication can be useful of course "I see you, your 200m, I'm on your port bow", but again requires a conscious cass.
