I have had good luck with the InReach as well. It is a 2 way communicator that includes the PLB functions. It does not have the strobe light or the homing signal, but it does have the additional function of notifying the people you choose. It can also be operated with one hand for the emergency signal, but sending messages one handed is a little more difficult. The new ones are smaller and do not need to be paired with another device. One version also includes a GPS to navigate with. The service is variable in price and adjustable to the amount of use you anticipate.

I would still recommend a PLB for certain activities (anything on the water, flying), but as we have discussed here before, the 2 way communications give a much more functional and flexible way to communicate in an emergency.

For work I carry both systems.
