The issue is the same with Spot or cell phone or satellite phone. Pushing the right buttons to send a "nevermind" signal doesn't take away the responsibility that should have been there from the beginning
DBD, All I read in bobpickering's post was instructions on how to actually make a SPOT issue a Cancel-SOS signal. He didn't offer any opinion whether that was all one needed to do, or whether more was required. Leaving out any opinion is not supporting the idea of walking off without contacting the authorities.
