The Medivac+ program with GEOS can be used in conjunction with the SPOT. This
service can be purchased regardless of whether or not you own a SPOT device. The
Medivac+ programs do NOT exclude HG/PG activities. So if you set up SPOT...use
this code for the Medivac+ (PLUS) for better coverage that covers our sports!

Several options are available:

Domestic to international coverage

Individual, couple or family plans

Annual memberships or short term memberships (defined by number of days)

One of the most attractive features of this special GEOS program is that it
provides coverage for the cost of repatriating you to a hospital near your home
from anywhere in the USA or Canada (if you have chosen the North American
option) or anywhere in the World (if you are an international member), avoiding
a possibly long stay in a hospital many miles from your family and friends. The
upgrade covering international travel throughout the world is available at very
little additional cost and you are entitled to use this valuable service from
the moment you are just 99 miles or more away from home!
