Welcome to the forum Mecacate.
I have never used the Royal Sabre but I know a lot about
Tesoroes. I have five Tesoroes and have owned others.
The Royal Sabre is kind of a unique Tesoro. Some older
Tesoro users sware that the Royial Sabre has the best
notch of any Tesoro. I tend to believe these guys because
they really know what they are talking about.
The Royial Sabre has two tones. The lower tone will be below
the notch, which is cool.
The Royial Sabre also has something that I think no other
Tesoro has. You can tune out surface targets. That can be
neat when trying to hunt where there is a lot of surface
trash that you don't want to mess with.
If you have the patience to learn the Royal, it should be an
excellent jewelry and coin machine in the sand.
But, it may have trouble in wet salt water sand. Most VLF
detectors have problems there.
