Can I use this to send out a signal that people can track with google maps? or is it just a beacon for emergencies?

Responded on

This is just for emergencies. ACR has new beacon coming out soon that will the ability to push a button that will people here I am and I am OK. There will be a subscription for the function. However there is no need for a subscription in order to use the emergency functions on the beacon. If you want something for true emergencies this is the product to get. If you want a messaging device then get a SPOT. The ACR products are designed as a life saving technology and are the most reliable.

What's the difference between the I/O PLB and the I/O NH PLB?


Best Answer Responded on

The only difference between the two is the NH model uses Non Hazardous batteries so you don't need to dispose of them according to your local hazardous waste ordinances (they're a bit more friendly to the planet). There is no difference in operational specifications or useful life between the two types of batteries and likely once all the non-NH models are sold, the NH will become the only option.
