No physical keyboard so inputting the text will either be through a soft keyboard on the display or through a tedious process using the toggle/arrow button. Hmmm, that might work as long as the 9-1-1 is a single button and easy to do under stress. This SPOT-DeLorme device might work for checking in and calling for non-emergency assist, but so does a cell phone. I'll wait for more details.

Regardless, I ordered a FastFind which should arrive with my RSK M-4, so I have the PLB issue covered.
