Spent an hour 4th October with the T2 SE fitted with the Mars Tiger coil. with setting 67 disc17 and mostly sounds of 2C but some of the time with boost. Five late Roman "grots" the last coin found was this Silver Siliqua of Magnus Maximus A.D.380 or so. Reverse Roma seated mint Trier Germany.Very please with the Tiger coil much lighter than the T2 standard coil and sharper on the signals.
