For years I have been looking for a way to communicate with students while in the spray booth. I ran across a piece of equipment that may be usefull to others. The device is small and attaches to your belt and a neck microphone touches your neck at the throat area. The sound is amplified it comes out sounding like your voice and clear to the students. The cost is under 300 dollars for the devise. The best part is that I no longer have to remove my mask to communicate properly.

The web address is www.saltillo.com The piece of equipment is a Echovoice EV4 my local supplier was Health Science  office 800-841-8923 fax 609-924-0793

Important!!! Earlier I said we paid under 300 for it, I was wrong.  We paid 379 plus 20 shipping. Great product could be a little louder but still worth the purchase.
