I have been out of action due to the English weather! BUT I did get out with my T2 Special edition on Saturday 28th January. I visited a grass site that I have recently had permission for. A number of signals including a George 3rd 1/2d then a Toy bath !! but the best find found at 13 inches was an 11th century A.D. Shield Boss these were fixed in the centre of a warriors shield. I used boost setting otherwise Sens. 75 disc 18. .as you can see it was fitted to a sheet of iron within the shield. Size 6cm x 6cm copper alloy
