Hi Raven, there are plenty of posts about people being extremely successful with these machines. I would feel very confident in saying that it is easier to find "happy" posts than "angry" posts about this machine. Most people complain about 2 things on this machine: the headphones and the knobs. I have done extensive tests on the headphones vs. others and have never found a target that I couldn't hear with the stock phones that I could hear with aftermarkets. I am not saying that certain aftermarkets aren't more comfortable or slightly clearer in tones, but aftermarkets, do not find targets that the stocks can't find. The knobs, for me anyway, make perfect sense. The knobs are designed as the weak point because if you have firm set screws on the knobs, rather than wearing out the knob, you will actually damage the circuit board inside the machine. One thing has to give and I think it was the absolute correct choice of Minelab to let the cheap knobs give (eventually) rather than making the consumer pay the high price of fixing the circuit board in case of over-turning a knob. If you want "firmer" knobs, as some do, change them out for $25 but I think its good to have an external weak point that remains cheap. The headphones are fine. If one of your concerns were the phones, forget about them. I have found hundreds of gold rings with these machines and I can't imagine that "better" phones would have given me better results. The only real problems I have seen on these machines relate to neglect. I wash off my Excals every time I get out of the water and I use sprays on my coil wires in order to maintain them. Most complaints you hear will be of "deteriorating" coil wires and these are due to people bringing their excals to the beach on a regular basis and not maintaining them properly. Excals are not capable of ignoring physics. If you maintain these machines, they will last a very long time. On the other hand, if you neglect them, they will fail and cause newbs to post hate-mail on them in a matter of months. Treat this machine right and it will return the favor. Thats what I have found. I literally make my living using excals and I have never had a problem. Please feel free to contact me with any further questions but i would also strongly recommend calling Minelab directly to ask any questions you may have. As I stated before, forums and dealers' words are one thing, but hearing answers to your questions from the manufacturer directly is a completely different thing. I have spoken with Minelab about infinite questions and they have always happily helped me. Good luck and please let us know what you end up doing. -Marc
