Both units have built in GPS. No need for any IR cables.
Simply sink, push the activate button and tread water until the CG arrives.. It's that simple..
Both units are registered to me.. I will provide the password to each (separate) online accounts. The neew owner(s) can simply go online and change the contact info and password.
Both PLB's have all the paperwork, manuals and boxes (boxes are a bit beat up though.. sorry)
