Had a problem with a my Sand Shark battery leakage, sent it in to Tesoro about 6 days later I had a message from Robert to give him a call about my detector. Due to my work schedule I couldn't get back with him for several days and when I finally made the call he was out of office so the Lady transferred me to Rusty Henry who is just amazing, talked with him for about 20 minutes as He told me some great treasure hunting stories and said that He would check on my machine asap this was Friday. Got call this morning from Mr. Henry and he informed me that my detector was fixed and that He was sending it out 3rd day shipping and that I would have it on Wednesday or Thursday so I would have it before Christmas Holiday and even charged me a whopping $36.00 and refused to let me pay for shipping! Thank you Mr. Henry and Tesoro Company this is the reason I use your detectors and always will.
