Sandman is correct. It would be easier if you ask the questions as they come up and then we can answer them.
If Sandman started posting all he knows in general, TN would run out of hard drive space quickly.
I can tell you this, you bought a great detector, having owned 2 of them in the past and still own one now.
Best way is to read the books as Sandman suggest...., Go hunting, start learning the detector, then ask questions.
I will give you a couple hints to help. On pinpointing, the toe or heal of the coil is the sweet point. When you find a target, back the coil up and slowly move toward the target, when it first sounds off, it will be at the leading edge of the coil, works the same on the heel as well if you back it up towards the target slowly swinging it. It is extremely rare that I ever use the pinpoint, as slows me down and I can always find it in disc mode.....
If your hunting wet sand where the tide has been on high tide, or in the surf, adjust your sense down till it is stable. Do not be afraid to do this. You can try auto, but if it starts falsing or becomes unstable turn it to the right till it becomes stable. I use either no descrimination to a max of 1.5, most times none. I advise you use none, and dig everything so you can learn what the tones mean.
If you have the stock shaft, consider getting a straight shaft and or neck, chest or waist mount the controls to take some of the weight off of your m. I also highly recommend a harness and bungie. I can hunt for hours with no pain with mine as I use the harness on my Excal and the Sov GT's.
My last suggestion is to get the biggest scoop you can find. The bigger the scoop the less time you speed recovering the target, and the quicker you can move on to the next target. Don't do like I did and buy a $50 scoop and think "this will do"....Believe me it will either break on you, or you will spend 4 times as long recoving a target as you would with a good scoop. Mine is 8.5 x 12 inches, and if I can find a wider one I would buy it.
Why waste the time, it is the one thing you will never get back....right SM..... 
Sandman, it is good to see you are doing better my friend, you helped me a lot when I first started and had a ton of questions....I am still a "Newbie" but your hints, suggestions, and answers to my questions help speed my learning and shorten the learning curve. Thanks.....
Good luck and good hunting......
