Gotta run the sensitivity high on any machine if you want to go deeper! Forget the numbers look for repeatable targets and sometimes if you’re in the woods or someplace that you can dig a big plug without worrying about making a mess you dig iffy signals that’s how you really learn your detector! Not on pre staged holes but I appreciate the effort you made making the video!
The CTX needs the soil to bring the signal up to teh coil. Many times I find a deep signal, then dig a plug and lose the signal. It still pinpoints, but the CTX will not detect down an empty hole very well.
Tarsacci will hit it without any problems. The MDT technology works great on gold rings in almost any soil, including salt/alkali. IME Tarsacci is the deepest deepest IB detector available, especially for harsh ground conditions
You need the hole filled first otherwise the hole can give a false signal,for deep gold with the d2 try sensitive program. Sensitivity 98, reactivity 0.5, audio response 5 and keep everything else as the stock program and ground balance, it does help with deep targets to ground balance the d2. It's hard to give a program without knowing your ground but these settings run stable on my ground where there are not many signals.
Seriously ? You try all the possible settings on the D2 and make zero adjustments on the 3030. And then tell me please who detects with zero reactivity 😂 This test is just ridiculous. Learn how to use the 3030 first.
