@petesenior and gonzo,many thanks for your replies,i have a little experience with a Pulse machine but why i pounced on this one machine was the fact that it was a bargain price,i wanted one for specific beach use as i have never done a great amount of beach work,but when all the permissions are out of bounds during the summer then the beach option sounds rather appealing.Still going down the avenue of another Pulse machine and also seriously looking at a new Nexus MK11 as well for a main machine.
The challenge if you like is learning about beach detecting as the skills of the regular folks who can read the beach and how the sand shifting etc is really a learnt art in its self and can only be gained by experiance,always like reading about folks who can read the beaches and how these shifting sands can move finds around into specific locations is mind blowing,but that will never happened here as i just would never gain the hours on the clock that folks live near the sea can gain every day.
