I can't really imagine this having any advantages over a PLB which are fairly inexpensive and already built to be waterproof and impact resistant. PLBs are monitored from orbit by COSPAS-SARSAT and modern versions have active location reporting which nearly guarantees fairly rapid reception and location fix. Satellite monitoring of aviation guard (121.5) has been officially ended by COSPAS-SARSAT and I'm not sure it ever monitored marine radio. Radiolocation of VHF 16 can be done but is going to be substantially more time consuming and less accurate than a COSPAS-SARSAT report - accuracy requires having nearby vessels properly equipped or sending an aircraft.

They are not inexpensive. In Finland you need a Radio Operator Licence and pay some 20€ annually and also you have to pay for reprogramming the special "National ID". And thus this mostly useless device costs 400€: https://www.marnela.com/product/1304-01261 https://www.marnela.com/product/1304-01261 Some 40 years ago I made 2 Mhz emergency Morse transmitter from RCA Cosmac, because I planned to spend a summer on Antarctis. It worked quite well with long ass wire antenna. But they do not monitor that frequency anymore and nobody understands morse.
