I'll start as many threads do here at Metal detecting beach or water.........

One thing I am not certain of is best coil size to use?
I will use beach programme on Etrac and would like to use SEF 18x16 coil for max ground coverage. Do larger coils become unstable on wet sand or are they ok?
Really not sure what coil I should opt for. Stock, Ultimate 13, SEF 18x 16 or SEF 8x6.
Looking forward to taking the boy camping if weather warms up and trying my hand on the beaches.
One more thing do you use sand scoops? They look a lot easier than bending over using a digger.
Thanks for looking in
