but includes 2 way messaging. The cost per year for the service is more the cost of batteries for the Epirb, but it has a lot more functionality. Including the ability to truly test it routinely. The story that Larry referenced below illustrates the problems otherwise: newly certified ACR Epirb failed within 30 minutes, it was the old, out of date, obsolete one which saved them. The inReach provides tracking for relatives piece of mind, SOS capability with confirmation that it has been received, and limited ability to communicate situation, circumstances, etc. through 160 character SMS. It is submersible and small enough to be wearable. I'm not sure an Epirb has any advantage - maybe the government run multiple response centers is some comfort. The SMS simplifies the decision making on when to pull the trigger: an Eprib is an all or nothing device, you press the button when you are prepared to abandon your boat. I have read numerous stories involving whether to push the button in the case of medical emergency, or vessel disablement (distinct from foundering) etc. Sat phone serves the same purpose, but it is unlikely to survive the trip into the liferaft.

I will probably buy another Eprib too, but I'm certainly less thrilled about the idea these days than I once was. What I would really like to see is a combination PLB and AIS locating beacon. A crewman cal one on deck ould wear this, deploy it after falling overboard and have pretty good assurance of being located quickly. Right now you can get either device, but the combined weight would probably drown you .
