You did good getting the Silver uMax. I have one and swear by it. Tom at Miller MDZ is a great person to deal with. He uses most of the detectors he sells and is very knowledgeable.
My opinion- Start hunting with disc. setting just short of penny. This knocks out pulltabs, most bottle caps, nickels, and of course rings. BUT it will be easier to learn because you will be cherry picking coins. This is good because you will experience success right away. Also you will know beyond the shadow of a doubt what a good target sounds like. Good target= nice clean short tone on both edges of the coin when you pass over it. Turn 90 degrees, get the same thing, dig, it's a coin. If you get double blips or crackling on one edge it is most likely a bottle cap or trash. Crushed bottle caps can fool ya. X over the spot and note the tone. A coin is relatively small and should give a short tone. If you move the detector coil 2-3" and get a tone it is a bigger target like large iron or aluminum can. Pinpointing is easy. Check from both directions with short sweeps and when silent the target is right in the middle of the coil. Practice this with your eyes closed and a penny on the ground. When detecting with disc set as I stated you will get pops, clicks, clipped signals. This is good as you are in a trashy area picking up short hits on items that are partially discriminated out. Slow the swing speed down at this point and sweep this area real good and slow. If you do this when you pass over a coin you will get a nice clean target sound. The Silver uMax is an expert at picking coins out of trash as it has great target separation and fast recovery speed. Place a penny on the ground and pull tab 1" to one side a nail 1" to the other side. The Silver will find the coin no problem with a slow swing speed. Take it a step further and litter a small area with trash and few coins to practice. I find my best finds in trashy areas. I think others just miss the coins in the trash. This is where the silver coins are in my opinion provided the age of the hunted area is older.
As you get confident on the use of your detector with the cherry picking high disc setting you can lower the disc. and dig more. I hunt silver and trashy areas so my disc setting is usually higher.
MOST IMPORTANT. When you are in a public area like a park or playground dig smartly. Cut a small U shaped plug flip the sod back, and most important, place any removed soil on a drop cloth. Once your target is retrieved lift the drop cloth and dump the soil back in, push the plug in and stamp down firmly. When you are done there will be no sign of your presence. I recommend the drop cloth because all the dirt gets back into the hole and leaves no evidence of your excavation. Park employees that have seen me do this are most impressed and I sure that is why the never bother me except to shoot the breeze once in a while. Get a Garrett Pro Pointer AS SOON AS YOU CAN AFFORD IT. This will keep your digging to a minimum and keep your holes neat and clean. With a pinpointer before digging check the surface for the coin. If the pinpointer hits on it you can just make a small slice or shallow 2" plug, pop the coin, push the cut closed or the shallow plug back down and keep going. If you don't get a surface hit with the pinpointer cut a normal sized 4-5" plug flip the plug back, check the plug, if nothing check the hole. If nothing in the hole take some dirt out and check until you find it. Your pinpointer will also allow you to size a target in the hole up to determine it is a coin or larger piece of trash such as aluminum can.
Good luck and if you have questions please ask!
what he said! +1..silver u-max is a "sleeper",and one fine detector!
it WILL embarrass pricier detectors,especially in trash! once you get the basics
learned,and if the "coin" is available,GET the 5.75 " concentric coil. just
an "outrageous" coil for "junked " areas.and will get silver down to about 6"
tell you what! been snipin' coins for over 33 years,and just got rid of a f-75!
guess what i am chasin? yup! a silver u-max OR a whites m6 BOTH detectors
are "crackerjack" really tough choice for me! i know both are ''sleepers" in their respective line-ups,
but guys like me,KNOW that complicated is NOT always best. i'm just sayin'..good luck!
