For me I don't worry about all that stuff, all I do is turn the XS on and go. I pick out signals and dig. If I am getting to much falsing I will switch to semi-auto - that's it for me.

First of all, the explorer does not vary the transmit power. It stays the same no matter where you set the sensitivity. A few people have hooked theirs to an oscilloscope to verify. What sensitivity does change is the amount of signal strengh that needs to be seen on the receive side of the electronics. High sensitivity means a little change gets processed, less means a bigger signal is needed.
If you are waving the coil over the ground and detuning until threshhold tone is heard constantly just means you are turning down the sensitivity until it no longer sees any targets. Kind of defeats the whole purpose. And then switching back to semi-auto basically lets the explorer tune the sensitivity back to where ever it feels it is best. That could be much lower or higher than your manual setpoint depending on the amount of ambient electrical noise present and the amount of trash in the ground.

I didn't care for the guy's video. He suggests going in manual and upping/downing till you get a stable threshold. That part's fine and a no-brainer. But then to suggest that people subsequently go into auto-mode from there, and therefore can hike up the sens. some more, is illogical. The machine would be merely lowering your sens. back down, automatically, to wherever it senses less chatter/falses. So you're not actually getting more sens, IMHO. For example, 32 with auto-tune on may actually render you down at a sens. of 11 or whatever. And believe me, the auto-tune feature will always err on the side of safety. It will tend to soften signals in the name of stability. I'd much rather use my ears, push the limits, and set it to *just* where it starts to crackle. To rely on the machine to do all that will only let it potentially over-compensate. This would be extremely true when you're in an area of lots of iron and other signals, where it would seek the most-stable, seek a threshold, etc.... I'd rather put up with a little chatter and noise, rather than risk that it could/would treat deep whispers as part of back-ground fluttering that it chooses to "smooth" out. Let your own ears be the discerning factor, not a computer.
