Rowdy...that's good to hear. I have both the Excal 1000 and the DFX, but mosty use the 1000 at the NJ beach. BUT...my arm is starting to KILL me !
What settings do you use and where are you hunting ( salt water beach ?). I have found a nice 14k bracelet with the DFX as well as some silver toe rings. Sometimes I think the Excal does go a little deeper, but I may have to bring out the DFX and fiddle with the settings a little to get more depth.
I use a modified Relic program with the preamp at 3, AC sens at 70, DC at 40 and it does well. I can't bump up the pre-amp to 4 on the beaches I hunt because it becomes to unstable ( but I have not tried turning the AC sens down so I may try that).
I always like to hear hunters hitting gold on the beach with the DFX. It is a really great detector. The reason I use the Excal more is because I get into the suds and it's peace of mind more than anything...I don't want my DFX fried buy the salt water if a wave decides it wants to greet me.
