I just sold my HH Pi because you have got to swing it slower than my surf master. Don,t get me wrong the HH Pi digs a little deeper and is a little more sensitive on small gold but I cover about 4miles between tides ( 4hrs )
I have found small gold and silver that I think my surf master up graded by Mr bill wouldn"t have found
