LEAVE IT IN THE FACTORY PRESETS for a short while
...and I believe I can truly shorten your learning curve as well as cut down on the level of frustration that might pop up.
LEAVE it in the factory preset conductive sounds settings.. while hunting in the smartfind screen for at least 5 full hunts.
As a forum moderator as well as having some input on Andy Sabisch's Explorer/E-Trac book...the number one thing I get asked about is "settings".
Don't mess with anything for some time. Those preset settings are there for a reason...and that reason is to help new users adapt to the language the SE speaks.
You will have time to learn the settings and what they do
after after you have familiarized yourself with the vastly different language the explorer speaks.
IMHO the worst thing a new explorer user can do is switch anything at all...especially switch back and forth between conductive and ferrous sounds.
That will completely change what you hear and how you hear it over deep coins....and probably confuse you at this point.
Take your time...swing very slow...and do NOT worry about anybody's settings right now. There is a crucial time frame where you have to spend some quality time with your new friend...the SE...and nobody else. That time is the first few hunts.
Pay close attention to the barrage of sounds you hear...the nulling...the instability...etc...and don't get frustrated.
ONLY 2 things I would even consider changing from the stock factory learning settings which is pretty much a coin program....
1) possibly set the iron mask at -22 on the SE while continuing to hunt in smartfind screen(-6 on XS and EX2).
2) The only other thing I would consider changing would be to put the sensitivity in semi auto and set it at 26 which will GREATLY cut down on the falsing and chirping..
Both of those change suggestions do not even need to be made IMHO...but if you must tinker...then tinker with only those two things.
Everything else....I strongly recomend leaving alone for a few weeks...and leaving it in the factory preset settings.
Do NOT try too much too fast...just have FUN.
These Explorers are more than capable of hitting 8"+ deep coins right out of the box in the factory preset mode.
Once you have quite a few hours on it...and have familiarized yourself with the "language" it speaks...then you can start to piddle with settings if need be.
You might even decide at that point that you want to give ferrous sounds/AM a shot. That is a proven method as well.
For now though...trust me...leave it as I suggested for a few hunts...then when things start to click a little...you can start piddling and tinkering
Of all the things I get asked about through messages...this is the number one thing...and my advice never changes.
I think it's a big mistake for new users to get caught up in what other's settings are and they try too much too fast...then get discouraged and sell the Explorer.
Just take your time...enjoy...and get a "feel" for the explorer before taking big leaps...and the learning curve will lessen a bunch.
After a few weeks or 5 full hunts...whichever comes first....then start pickin' the brains of everyone on this forum for tips...suggestions...advice...settings to try...etc. This place is a wealth of knowledge and there a ton of talented hunters here who will help you in whatever way you need
