I recently bought a new CTX 3030 and was worried about the learning curve of going from an 8 year old Explorer II to the CTX. I searched a cut over hay field this past weekend for CW relics that I last searched with my Explorer II back on New Year's Day, and in much softer ground that day, I found nothing, but in 3 hours with my new CTX (17" coil), I found 9 three ring minie balls, 1 Williams cleaner bullet, 3 pcs of melted lead, and 1 Yankee eagle button. All of these finds came in rock-hard, dry soil, and the targets were 12 to 14 inches in the ground. I was surprised how similar the tones are on the CTX to the old Explorer, so if you're debating about upgrading like I did, it might open up some of your old places to some new and deeper targets. I can't wait until cooler weather and softer ground!
