If you see the squid following your jig then slowly stop winding it and let it sit stationary and if the squid doesn't attempt to grab it jig it a little. As for the 10 in an hour part, you could get 10 in 5 minutes on a very good day but it could also take an hour to get 1, just depends on where the squid are and how fussy they are. Around balmoral, the island is a good spot, as is Wy-ar-gine point, those two areas are probably easier to fish from a boat even though they can be accessed by land.
Good Luck
