I agree on requiring a locater beacon. I like the idea they are using on the bear containers (refundable deposit). Where I've got a problem is with the system they want to use. For less than two ounces more a PLB WILL cut down on the time. If the GPS can pick up enough satellites it also won't require triangulation to locate you. With the extra receivers that will be needed, the cost for the systems used in one rescue will probably be as much or more than a PLB. They could cut down on the expense by also operating as a dealer by selling PLB's & servicing them (replacement batteries at dealer price for the rental/loaner units).
