Thanks all for the great advice on here regarding my choices between the excal, cz21 and tiger shark. While all are likely great detectors, I've always wanted and Excal so I have one coming. After some PM's from members I decided to buy new on the water machine. I know it's only a year warranty but thats a year and I know what I have when I buy new. Got the 10" coil model Excal btw, better coverage. It will be a freshwater detector most of the time but now I at least have some reasons to be trying to get down to the coast more often! I'll likely just keep the machine stock until the warranty is up then look at adding a pinpoint mod, maybe some better headpones. I will go ahead and get the Anderson straight shaft right away though as well as knob protector. Any good reading to start with besides the manual before she arrives at the door step?
