While Im new to the Golden, Im not new to Tesoro's. I can echo alot of what Mike says, Bill. The Golden is light and easy to swing. It hits good on good targets and sounds crappy on trash. It has all of what the Tesoro mid-line has, plus the added tone-ID features. Id call it a Silver uMax PLUS.
Where I live the GB is good, as there is litttle mineralization. So, I sense that the depth is there, if needed. It just has a quiet strength about it. I have run mine so far at moderate SENS settings and havent felt like Im being hampered. The higer settings and the BOOST is there, too if needed.
Id recommend you get some Koss TD/80's or some other pair of digi-phones, as the audio is full of nuance and those big old Calrad headphones are sort of muted. The tone ID is a sing-songy sort of thing at times and take some getting used to. The best way is to hunt in low DISC at first and dig lots of targets - so hunt where the digging is easy! It is real good for "townie" sites.
