Because I spent all summer on the east coast in Italy, far from home where I have my DSL internet connection. No way to follow the threads from there with continuity so I've been silent.
I really found a LOT this summer even if competition is heavily rising here and this season as been a "chess" like game in the water against all the other guys .
My Surfmaster PI Pro proved to be reliable and accurate. All the people I've seen here use Excaliburs and it looks like they leave a lot of gold behind. I have a couple of explanations for that:
1) They all use 8 inch coils and that gives me some advantage on depth on coin sized objects since the Sufmaster has a 9.5 inch head
2) They search too fast. A quiet, careful search is better than running around erraticly. The square meters you can cover for the same amount of time are the same if you run or if you do it step by step.
My Surmaster anyway has its own pitfalls: it is a noisy detector, you have to be really skilled at distiguishing between false signals and good ones and , as I always said, the head shape is not optimal for underwater use as it has a considerable drag and tends to flip up with strong underwater currents or waves. Overall it is a good detector and I suggest it for skilled people.
I include a picture of the rings I found in 90 days of search, no cheating. On the right crap rings, center gold rings, left silver rings, plus a picture of my equipment.
HAPPY HUNTING!
Cheers from Italy
