I got my Sov. Tuesday and today I took it on the beach. It wasn't as heavy as I thought it would be. Found many coins and other items but no gold yet. The beach became crowded too fast. Got a nice solid hit with room to spare on a coin that was 12'' deep using the standard coil. Question...Sometimes whenever it hit a target and it nulls. I know that iron will cause it to null but what about deeper targets? Disc 4 notches, sensitivity just out of auto.
