I pretty much absorbed all the info on p2p. I ordered the book, "Water Hunting: Secrets of the Pros" There really isn't much too be said about the Infinium. It's simple yet powerful. The hardest part about it really is the digging and learning the nuances of the tones which doesn't seem that hard to me running the SE in AM all the time. I just have to get some rain gear and such for beach hunting during the colder months which will not be too often and I'll be all set. I only work 3X's/week so I have more time than the average person but right now with the beaches being out of season there isn't much chance of making a good score unless we get some stormy weather churning up the oceans my way.
