Here's an update. I had weighed all input from here and a couple of other forums and some beach hounds I know. I had decided on the tesoro tigershark, because of the sensitivity to the smaller stuff, the depth rating and the lifetime warranty. But, recent events from Tesoro's manufacturer has changed my mind. I found out that the new Tigershark's are coming with the coil being hardwired and you cannot change it. So, with that being said I sold my backup detector and have chosen the Excalibur II. I was really wanting the TS but with the thought of being stuck with one coil doesn't help. I was hoping that the rumors about the hardwired coil was false. Sorry Tesoro.
