If you like analog detectors then you would love this one. The C/B versions were the last of the 5900 series and are hard to find. This detector I would rate a 9 out of 10, and works as it should, comes with the proper 950 Blue Max coil. I said I would never let this one go, but at 76 it is just getting heavy for me. Would love to see it go to someone who appreciates these as I believe the are one of the best analog detectors ever made. Price $300.00 shipped.
