Thank you for all the information, yes sand was wet not soaking but damp. Will have to look for another machine for wet sand .

if it very flat and even without ripples there's a few thing that can be done to help the situation but it will always be a compromise

A mixture of all or some all

smaller the coil the better
swing very very slowly
swing exactly the same height above the sand
increas the height of the coil above the sand
it will sound of if you hit the ground
use more discrimination
lower the sensitivity
