Glad to see that Doug will be testing out the new ACR PLB.
While I love the features that SPOT offers I've had reservations about it for a few reasons. First and most important is that there is no ability for SAR to track the signal. With the 406 bursts, SAR aircraft can home in directly on the signal. Just flying to a waypoint may not always be the best because there may be no visual way of verifying you are in the correct spot. It also makes it easier for ground teams to home in directly on the signal. Often communications deep in the woods or up in the mountains from a ground team can be spotty so if the gps coordinates are not right there may be no way to verify the location. What happens if your SPOT cannot get a signal out because you are under cover? If a SAR aircraft gets close they'll be able to pick up the 406 beacon that may not be able to make it to the satellite.
Second, the service is expensive at $100/year.
Third, there are no standards on the quality or testing of the SPOT so it is left up to the manufacturer to decide if it is worthy. All COPAS SARSAT beacons must meet rigid standards and be fully tested then approved.
A 406 PLB in combination with APRS is a great way to go.
Many of the CAP planes now have Becker DF units which can not only home in on the signal but also display the signal's coordinates and registration information.
