After four years, or is that five? I find the Sovereign GT surprises me more and more often. Nothing will beat it on the beach for coins. Small gold? I have found several gold rings, the smallest .95 of a gram and was broken at the solder joint, thus eliminating the shorted turn effect.. I have also picked up many tiny silver objects like sections of earrings etc, all with good repeatable signals.
What has astounded me most is the sensitivity to tiny copper objects. In one area where I search a boat has been burnt or just rotted away, leaving a legacy of copper nails screws etc. Amongst these are tiny copper roves. Roves are small copper discs placed under the heads of copper nails to increase their purchase in soft wood such as King William pine often used in boat building in Tasmania. I have detected roves 3/16" dia with a 1/16" hole at 10 to 12 inches. sitting under the sand on top of clay. They are devils to locate in the sieve when covered in mud, sand and clay.
That said, I'm sure the Sovereign GT is as good as you can get for the cash outlay. Also remember it is a pleasure pursuit, not a living. You probably won't get rich.
