Hi, I use a carbon coil now for 1 year
14 inches on my two pulsepower PI
Goldscan 5c and Goldquest ssv3
only on the beach in France,
big advantage, it is really waterproof !!
it takes very little in the wet sand,
alliances of less than 1 gr smoothly and depth
my best taken with the carbon has been a gold coin 2 escudos !
and a lot of gold, a little over 150 grams for the year 2013 ...
a question, the new carbon coil, wire litz,
you are her most sensitive / quiet,,
that the old model ?
