Rusty the service manager called with the 411 of what happened. i now can call Tesoro and ask for two humans by name. this is unbelievable. i have Rusty's' cell phone number. he talked to me for 15 min while his buds loaded his trailer with re-bar for a footing! if you are thinking of buying a awesome detector, and would like to have customer service like you were a good friend of the owner, one word folks "Tesoro"!. thanks Rusty! thanks Christi! you are the best!
