Depth as the CZ3D does. Coil for coil. Do they make a 5" coil for the ID Edge?? I am going to make a pin pointer out of my Excell since they were too cheap to make a 5" coil for it. Gonna use a Sunray 1" coil. Hey, I ain't got nothing else to do, since I am retired and I love it. 
Should have retired 5 years ago. Later Ya'll Jerry aka Tinfoil
