I am looking for a good Tesoro Water Detector..I will be doing mostly shore and up to waist,,no diving..Also I will only be in fresh water lakes..I own a Minelab Sovereign GT and a Tesoro Cortes...I think Tesoro makes a Great Machine and with the warranty how could you beat it..I don't know if a PI-Pulse machine would be better or what..I've checked out the Sand Shark and like it but not sure..Also I've looked at others like Whites but I keep going back to Tesoro...Can some of the Members that water detect let me know ASAP....Thanks..John.......
