Just received my water detector a CZ20 with an 8 inch coil.I have used CZs and had to log a little time on the Cz20 routine double hits or four ways on targets.Even though it has exceptional pinpoint ability I lost targets at depth but with the Bullseye pin pointer I recovered these targets saving time and lowering stress.The CZ20 was belt mounted.When I left the school yard a gentleman explained that the school was built in the Twenties.He also explained that everyone searches the old football field but there was an old track in the the far corner where no one ever searches.So Sunday morning I would bring the Sovereign XS and search the area and see if it had any possibilities.In contrast with the Fisher the Sovereign with the straight shaft felt light.Even though I only searched for about two hour I recovered twenty five coins 3 quarters 5 dimes 5 nickles and 12 pennies only 1 wheat.The Sovereign with the 8 inch Tornado locked really nice onto targets,the 180 meter was only wrong a couple of times,which one was can slaw at about a foot. The sun ray probe helped recover dimes as deep as 8 inches that would otherwise have remained lost.After searching the old track area I would conclude that it was filled in and landscaped,because there was a lot of clad coins around 7 to eight inches.The Sovereign seemed to have great depth very easy and comfortable to use,especially when compared to the CZ20.
