Sorry to learn of your Excal issues, Mark. I feel for how you and others are beyond frustrated with the lack of service and support from a company that has been the backbone of your hobby. Hopefully, Minelab will get it together. Today, I received my new back-up detector. After much research and thought, I decided on the 8" Tesoro Sand Shark. I've owned a PI machine previously so I am familiar with the pluses and minuses. Any suggestions or tips on this detector and it's idiosyncrasies would be much appreciated.
