I've had mine for about three years now. This is my first metal detector and have been very pleased. I'm not able to hunt that often so I'm still no expert with this machine. I hunt coins and relics. A fellow who has one said since that was the case it is best to use it in relic mode. Is this so? I've never tried it any other way. Also what does, say, gold jewelery register as in relic mode. The silver rings I have found register as buckles. I usually dig everything that reads buckles because its usually clad, silver coins or some sort of silver jewelery. I rarely dig anything that comes up as buttons unless it reads right at 20, usually a nickle. What sort of stuff am I missing out on?
