In an average field with iron horseshoes, plough shear and coke.
Looking for small objects thin silver under 20 mm diameter
which type of coil on average will preform the best
figure of 8
concentric
DD
omega / 4B
Super DD
other I haven't thought of.
At the movement a prefer the concentric over the DD. Mainly for the accuracy of pinpointing and less cracks and pop around iron. Also rarely dig bent iron. Only large washers fool it.
I am fairly sure the super DD will be a waste of time due to the fields not being clean enough
The omega I feel would have some of the advantages of a DD with the ID and pinpointing of the concentric.
