I got lucky over the weekend and bought an extra clean used CTX 3030, came with stock coil, wireless headphones, AA battery pack and rechargeable battery, I had to track down a charging cable
I put AA batteries in and fired it up, right at the dining room table. I could max out the Sensitivity, with no problem, and using the 11" coil, it was giving solid ID's at 12 inches.
It's been about 7 years since I owned a 3030, I forgot how stable and accurate they are on deep coins.
Now I need some warmer days so I can take it for a test run
