Could they use this devise for coal miners and tracking thier wareabouts in location to mine disasters? Great product. If it was used in an underground parking facility then maybe could be used in underground mines. Rep Matheson is working on communication with miners underground and a bill is in the process if I remember right.

Should have tried it in Uppper Millcreek Canyon where there is no cell service.

This is a great idea. Now it will be possible to put the prisoners back to work on the roads and escaping would be hopeless.

Several thoughts to consider:

1. I have confidence in the tracking technology presented. However, I do have cost and operation questions regarding this tracking system.

2. What is the initial purchase price or replacement cost every 5 years, for 90 monitoring units? (90 x $500=$45,000)?

3. What are the savings when ankle monitors are compared to the cost of incarceration? For 90 prisoners (90 x $6=$540 for monitoring services) versus (90 X $70=$6,300 for criminals to remain in jail each day).

4. Now that we can electronically track the criminal's movement, WHAT HAPPENS when there is a violation? WHO is going to respond to each prisoner's wrong move, much less re-arrest them when necessary? Obviously, there are additional costs to enforce the rules. If we say 10 prisoners required a response, there is a cost (10 x $170 = $1,700 a day). Furthermore, if 30 prisoners decided to simultaneously go on the run (thus overloading the tracking system and the police), the cost could skyrocket. Who knows what the cost to law abiding citizens might be?

5. WHAT ARE THE STRICT CRITERIA required of prisoners? Good behavior! Then buy your own monitor to participate! Good luck to all of us!
