Since I started using my CTX 3030 with the 17" coil, I've covered a lot more ground and found deeper civil war relics. The only downside with the big coil is that it's harder to pinpoint and especially harder to locate a deep target that has been removed from the hole in the loose dirt. A 12 to 14 inch hole produces a lot of dirt outside the hole! About 2 weeks ago, I started looking for a pinpointer to solve this problem. Don't bother about checking ebay--used stuff goes for not much less than new. Save some time & call Bart Davis at Big Boy Hobbies for a Garrett Propointer. I just ordered 2 for my buddy and myself! Bart will give you a good deal!
