I appreciate all the info & tips I was given. I decided to buy the Silver Umax. I don't know what I am doing yet but walked around some today. I went to a crowded park nearby They had just planted all new grass! So I would not dare dig in the grass. I went down into a shallow creek. The detector was indicating something was there but I could not figure out what it was telling me. When I dug a little in the rocky shallow water it got all muddy so I couldn't see thru the water. Obviously I have alot to learn! All I have so far is the detector, stereo headset which I did not use yet. I am so new at this do not know what the headsets will do for me. I was kind of sad after not finding anything today but I am sure after I learn more about using it & the headset I will start finding treasures like coins & jewelry. The 1st two things I found in my yard were coke cans that the builder had buried. I am looking forward to trying it at the beach several times a year. I am so thankful to have this helpful group to ask questions & share my new hobby. Cathy
