No....stock programs are not "good enough". But.......they are perfect to learn and start your "own learning" because they are designed to be as easy as possible for what their intent is, and.....produce well right out of the gate.My main job is not "selling" detectors as my skill set is more appropriately used in other areas of where I work. (It kills me to not be more involved because detecting is such a big thing for me personally and hope my job can grow into that also...I'm good with teaching people.)
I do purchasing and sales in other products, but by default I'm there to assist w/detectors. Getting people comfortable with the leaning path "ahead" is actually easy for me and I bat high on this one. Don't concern yourself with what you "don't know" but enjoy learning more in little steps. (Enjoy each step and don't move on much to more for awhile.....elements of the factory programs are still working for you and eventually you'll be amazed at how close they are to how you end up adjusting your setting for most of your hunting.)
Once you have something "under your belt", work that to the point where you've become somewhat comfortable, and pick at something else to begin learning.....the factory programs are still covering your tail.
Respect yourself for each little strength you pick up as you go and build on that. It turns "nice" with each of us at our own rate of learning.
Aside from detecting, the V3i has the most easy and wonderful software on the market. It's beautiful,adjusts to our eyesight and hearing capabilities, comfortable to move through and pop around in, makes sense in the way it's layed out.....make time to just "sit and play on the couch". Unhook the coil from it, don't worry a nit about understanding it all at once,pay attention to how things are labelled....eat some chip,pet the dog, come back to it when you feel like it. This little exercise will do wonders for you when your ready to step into learning each aspect of this truly fine piece of kit and enjoy each smile as you learn each little "cool" thing. The factory progams are STILL going a long way in covering for you and are fundimentally close to the way we all end up adjusting them.
