There's a seeded competition hunt next month that I'm interested in entering.The detectors that I have to use are these, a Fisher CZ7A,White's Eagle Spectrum,An older Discovery III,and a Compass Coin Hustler. Would any of these detectors be competitive?Which one of these units would probably work best? Next,coil size 8inch vs 9.5 on the Eagle.Would a hand held pin pointer help in a seeded hunt. What are the digging tools usually used for these events.Finally any information or tips on a competitive hunt would be appreciated. Thanks Ron
