Protank 2 - Help!

[messy]

Hey. I've recently picked up a Protank 2 and an MVP v2. My Protank is emitting a high pitch sound every time I hit the button. Its seriously annoying, and it doesnt happen on my iClear 30.

Can you describe the high-pitched sound better? Is it a rattle, crackle, whistle, gurgle, etc? Clearos can make different sounds.

Have you tried a different coil? If not, do that first.
