Lately I have seen many local jails getting these. They seem quite effective. I have read that one county jail has found multiple smugglers by using this device. I also like the concept of not having to strip as much or any more. If anyone has any experience with these devices or even better yet any ideas for funding the purchase or grants that can be tapped into for such a device I would love to hear about it. One module I forget the kind (my bad) can be used 400 times before you receive the same dose of radiation as a x-ray at your local hospital. I think this would be great in visiting room and even staff searches. So please share any thoughts or feelings.
