does this device require dye in the freon to work?

No. It detects the presence of refrigerant gas to signal a leak. Dye is just another way to find a leak as well as soapy water.

When I'm using UV do I need special glasses?

Amber/Yellow glasses helped me a lot. I had a uv flashlight that lit up brighter than this. Since I was working on a system that had been repaired multiple times, there was uv dye from previous leaks. This is where the "sniffer" part helped. It has been a long time since I last used it, but it did work well.

Great Sniffer!

Very accurate sniffer. I monitor my manifold connections after a compressor change. Crack a fitting and the alarm goes off.
