We in Australia still have no solid information as to what has happened to Tesoro.
I imagine some of their detectors will become collectable. Like the Sand Shark, LST, the Golden Sabre. The Compadre has always been well received and performs above its weight.
I believe that at some time they made a tecta that was modular and could be converted from a gold machine to Coin and relic to beach. Don't think it was well received at the time.
There is a chap in the States who seems hell bent on condemning just about every metal detector that is not a Deus or a multi frequency digital machine. I watch his youtube vids and he does have some valid points, but as Tesoro followers we know that these machines work very well.
I will be holding on to my Sand Shark and LST. I also just purchased a Mojave out of curiosity. I do not have it yet but have read some good and not so good reports about this little tecta. I am giving it the benefit of the doubt. It is after all, a Tesoro and I have not had a dud one yet out of five different units. Even my old Bob cat was still going strong up to the time of sale.
Cheers to all and have a great 2019.
