yes-------The "I" version uses the COSPAS SARSAT system exclusively which means you will be located in about an hour within a 2 mile radius. This unit also emits a 121.5 signal which allows the ground crews to find you very quickly once they know where you generally are. This system is almost 100% reliable (unlike the GPS system) and will assure you will be rescued. The "I/O" unit utilizes the GPS system to allow for a quicker and more accurate location (5 minute acquisition within a 100 meter radius). However this is only the case if you can acquire a GPS signal. Otherwise it will default to the COPSAS SARSAT system as well.
