Set the discrimination just above iron and turn the sensitivity up until you get chatter and back off until the chatter goes away. (I never get chatter and run sens at 10+). Start by listening real well to the tone. Pass several times over the target real slow, turn 90 degrees and do the same. LISTEN to the tone you get. Is it clean all the way through, broken clean broken, etc.. Now turn up the Disc. and do the same thing. See if the target can be eliminated with disc. Now lift the coil up slowly and swing over the target. This will give you an idea of depth. If you lift the coil 1 inch and lose it, the target is deep! Now dig the target and see what ya got. Now find some available memory space in your brain and store this info! When you first start with the Silver this methods allows you to get lots of information from each target, allowing you to start to learn it's language. In about 4-6 hours of use doing this you will have a real good idea of whats down there before ya dig. Coins will become real obvious. You don't have a display to lie to you, it's all in the ear.
When I first got my Silver uMax I was not too impressed. I had been returning to the hobby after 8 years. I guess I was expecting the coins to just pop out of the ground! I bit the bullet, went out and learned the unit and I am highly impressed with this simple, little, light weight gem! Learn as much as you can from each target before digging and you will get good real quick. I spent my first 4 hours digging everything to learn all that I could. Remember metal detectors work off of target conductivity and many things in the ground can have the same conductivity as a coin. In the end you will be much better at metal detecting by learning on a great machine like this. You will not be a zombie staring at a display.
Dollar for dollar this detector has lots of performance for the buck. In the hands of an experienced user I have no doubt it can run with some of the bigger dollar units.
