I think Dewcon said it pretty good in the end of his post, but I will say it my way. The Whites machines have way too many things to adjust compared to the Explorer. When I had a Whites, I spent tons of time tweaking the machine trying to get more depth - it became a second hobby! Heck, I thought about giving up finding things and just have more fun adjusting my machine! With the Explorer I have it setup the way I like, and I may change the sensitivity, gain or a filter, but that is about it.
Grunt, you sound like a Whites user, you decide... I haven't run through this for a while, so I may miss something. Here is the way most folks use their Explorer,
1. Manual sensitivity set as high as possible with the machine still running smooth
2. Iron mask with about an eighth of an inch of the iron (left side) discriminated out
3. Conductive tones (this is the preset)
4. Gain at 7 or 8
5. Pick a filter Fast or Deep or Both (I like fast on)
6. Everything else at preset value
I can't think of anything else... this is why we do not have a list of "Programs" for the Explorer. It is very simple, and it goes deep even in factory preset!
Sure folks run things at different settings. For one, some folks like to run real high gain like 9. A high gain will make shallow and deep targets both sound like they are laying on top of the ground. I think you get more iron false signals that way too. Personally I like a gain of 7-ish. That will give me a quiet sound for deep targets and loud for shallow - it is a user preference.
There are different sounds and junk like that, I figured I needed to learn the machine without changing things like sounds - never really wanted different sounds, but the option is there. It would be confusing to a beginner to be switching those around.
A lot of folks like running all metal with ferrous sounds. I do that when hunting iron infested fields. The "Program" = Set iron mask to none, set tones to Ferrous.
Hope this helps and HH - BF
