message sets off a piercing alarm
on all vessels which receive it. Third, a DSC VHF radio
provides two-way communication. Lastly, a DSC VHF radio fulfills other purposes, like ordinary short-range comms.
Therefore, I would much rather have a compact DSC VHF radio on my person, than an AIS-SART, if someone would produce such a thing.
I do have a PLB in my life jacket, but that won't help much for an immediate MOB
recovery since the signal is not received on board. Also, I only have one of them.
I also have a 121.5mhz MOB
beacon -- two transmitters, and one directional locator. The transmitters go around your neck and go off automatically if they hit water
. I bought them from a person back from a multi-year cruise
; they are somewhat dated and probably need battery replacements
. I have not yet put them into service
. They must have cost a fortune -- I reckon thousands -- when they were new.
Better than any of this would be a simple, $200, very compact DSC VHF radio, in my opinion.
