[KarlS]

Is anyone using or used this coil and what is your thoughts about it. I'm thinking about adding one more coi to my arsenal and this time it is going to be coil made specifically for TDI range of detectors.

My spp is in the mail atm but I'm seriously thinking about razorbacks small 10x5 elliptical mono to go with the 12inch factory coil, from everything I've read the razorbacks do really good on whites Pi.
