Well done Lewy.
I put about 8 hrs on my unit over the weekend. No gold, however I picked up a few air rifle slugs at about 3". Around the 35-40 mark. I was using the all metal mode too. Ground was between 65-80.
It is good at Identifying steel around the 20 mark, foil at 65, buckles/bullets at 75. I dug all targets first time out now I am confident on the ID's.
One thing I noticed was that when trying to get a lock on small or deep targets the ID was wide and varied. If you bounce the coil up and down (instead of swing left and right) about an inch it ID's the target correctly.
I will put more hours in during the week.
