help with new sandshark

#1
This was only my second time out with the sand shark. Any help with the best setting for wet sand and shallow ocean water would be appreciated.
Haven't found much. Been setting the pulse at 2 0'clock,Threshold between 12 & 1 o'clock, volume loud.

I run mine "hot ".... Threshold set by ear to a mellow sound... Unless I am underwater... Then louder... I run the gain close to full blast... But it will go they batteries much quicker...
Great unit... Has found many items :) it also does well " seeing " thru a couple inches of rock!
