I don't know if it will pass through or not, but according to the manafacturer, if it does get confiscated, you just have to contact them with the flight number/day and time and they will replace it for free. Don't know, but it sounds okay.

ParamedicPete, thanks for the info!
Is the body housing plastic or metal?

I guess I'll get one and let everyone know what happens the next time I fly <img src="images/graemlins/grin.gif" alt="" />
