Hello. Welcome to CF.
This forum occasionally gets requests like yours, from New Members, that ask for everything known about a topic without divulging more about why.
Your user name is MOB and you want to know of all the devices for MOB location.
Are you a vendor selling the devices?
Are you trying to design or sell a device?
Trying to build a database?
Why do you exclude the AIS
and other electronic devices from consideration?
Is this for your own boat
What is your real purpose or goal?
A simple look into a marine
chandlers catalog or google
search should provide many answers. MOB recovery devices are often discussed on CF. you can find those previous discussions in the archives
of CF. A good online retailer for marine safety gear
in the USA
is Landfallnavigation.com. Visit that site and you can see a broad selection of MOB devices.
Since this is a topic you have already studied to some degree, I suggest describing what you have already identified or know first. Then others may fill in gaps of your knowledge.
Good luck and I hope this helps.
