Hi Katz-
You have a question about Patteren?
There are three different mode setting in the display-
Pattern AM (All Metal) Accepts signals from all types of metals, everything from jewellery to rusty nails. Like too many trash metal everywhere on the field, beep, beep,
Pattern 1) Accepts signals from non-ferrous targets, e.g. gold and silver coins. Rejects ferrous objects and non-ferrous aluminium foil.
Pattern 2) Accepts signals from most non-ferrous targets. Rejects those from ferrous objects and some non-ferrous targets, e.g. aluminium foil and pull tabs.
So, I tested it and really like to start with the Pattern 1. If beep, then change to Pattern 2 and see if there is coin or not.
Other question, Is this machine a turn on and run with it or is the learning curve going to stime one's brain?
Oh yes! I recharged the battery overnight, then I put it in the X-Terra 50 in late afternoon, the display show same way when you turn off. When I see the Pattern 2, before go home and took battery off for recharge, then put battery in there next day, it still stand with Pattern 2. If Pattern 1 or All metal when you turn off, then it still stand, no change. You don't need to adjust the setting every time when you start on the field. I recommend that you should test first, like put several coins, any metal, etc on the ground, so you can adjust the Pattern setting and see what you hear. Then just leave the mode adjust and go to the field. That is what I did and really love it. Many time, I push the button for turn on, then ready to go!
The X-Terra 50 is good machine, good price as under 500 bucks. If you have rich money, then go to X-Terra 70. If you have tight money, then X-Terra 30 or Ace 250.
If you have any question, please feel free to email me.
