Hello Drew,
I wish you the best of luck. My advise, keep the EII as a backup, you may want to go back to it. Most people here have probably heard my lament about the SE. I bought one four or five years back mainly on the advertised claim that it handled iron better. They quit using that claim shortly after I bought mine. I used/struggled with the SE for about a year. I have owned the original Explorer and the EII, so I had experience. Anyway, here is the simple but frustrating trouble I had. The SE would invariably ID small deep iron, like a square nail, as a coin. My EII will give a "good" tone one way on those targets, but once I turn 90 deg. and sweep again it nulls out (indicating iron). The SE would just say coin initially and at 90 deg. Very frustrating! When I finally switched back to my EII it was a huge difference - having trust in those deep, potentially great signals. I heard from quite a few guys that had the same trouble.
This is my opinion and experience. In order to combat this problem, I resorted to using the SE in ferrous tones (which helped). I do use ferrous tones in heavy iron, but I really prefer conductive tones (eliminates starring at screen). Soon after the SE came out, hunting in ferrous tones became much more popular. Gee I wonder why?
You will like the pinpoint. It is nice. I hope that you get a good one or yours works better than mine.
I have a $1000 plus backup machine that has not been used in four years. I will be selling it off soon to get something that I may actually use once in a while.
I did send it in to ML for a check up. They could not find anything wrong, fixated on finding the unit in pinpoint mode (I have no idea there), and acted like they had never heard of my problem before. They went ahead and put new "guts" in the control housing. I thought that was nice. Only used it once after that since I had completely lost confidence in the machine.
Ok, I spilled my guts again, sorry to be a stick-in-the-mud. It really galls me to spend over $1000 and find out it worked worse than the old machine. Many people swear by the SE. Most will tell you the "upgrade" is, at best, marginal.
Again, good luck and HH - BF
