I had sent my two Tesoro machines (Sand & Tiger Sharks) to be repaired to East Texas. Tesoro seems to have went out of business and this was the only place I found to have them repaired. I was given the referral from Kelly Co. That is where I bought the Sand Shark. Well it took a long time and I was becoming worried. A long time as in a year. I reached out on Treasure Net and found one person also is waiting for his detector a long time. I decided to wait it out because East Texas said work was piling up and parts are hard to come by. Glad I kept the faith! East Texas called me today and said they are all finished and rated for submersion. All tuned up and ready to rock. price very reasonable considering ET did not charge them room and board LOL. Thank You Keith Wills, of East Texas Metal Detectors.
