My new Delta 4000 from Kellyco is on its way and will be here in a few day! if it as good as people say the my Ace 250 and my F2 are going up for sale.
You'll love it. It won't let you down.
I found three more rings this weekend with mine; one silver, one 18K and another gold one with what I believe are 12 diamonds and 4 sapphires. I'm getting it checked out this week and I'll post an update. I think I'm still in shock.
These are from just under two weeks and I'm barely hunting after work anymore because there's no daylight left. I'm spending less than half the time I was when the days were longer plus I've been sick and not even spending a whole lotta' time on weekends. But, the Delta found all of these in the limited time I've hunted.
I still can't believe it. It even found that little piece of silver wire. The "nugget" ring is a fake. I know this because the gold paint is really peeling off.

I haven't had a run like this in months and I feel like I'm hunting at a whole new level.
Btw, 18K is ringing in around 53 on mine so when you get it, be sure to dig those trashy foil signals. You'll dig some foil and other trash but you just may get some gold while you're at it. You'll definitely pick up lots of nickels and easily sniff out tiny targets. Deep pinky rings are no match for the Delta.
It just LOVES sniffing out those rings. So far, I'm really impressed and hopefully, you will be too.
I have a feeling you're gonna' do very well with yours as well.
I see you already have a Euroteck Pro. According to the side by side comparison chart on metaldetector.com, these two machines are very close in what they can do. They both supposed to hit a US quarter at 8 or 9". IMO, in wet soil you can even hit a little deeper, depending on the target and conditions. Either way, 9" ain't too shabby on a bad day.
I've never used the ETP but that was also on my list before scoring the Delta. I'm assuming that if you like the ETP, you'll like the Delta as well. I hope it really lives up to your expectations and more.
Good luck & HH with your new toy. Post some pics of your finds.
