Opinions are like noses - everyone has one. Those who contact other's in private, unsolicited, to voice their opinions must be mindful of that. Those who read these opinions should wonder why the other felt thay had to do so - and be mindful as well.
I own a BOTH a Golden and a Vaquero, and whoever told you the Golden will not go deep should be swoggled. I found a quarter last season with it at a measured 11". It gave a sweet, clear high tone the whole way.
And yes, it has SIX tones for you to monitor. But like all things, if you persist you will find these tones purposeful and invaluable. There is one place I cannot hunt without them and the notching circuit working together, as they are so precise. Other detectors, including the V, can only wish to produce in that spot.
Digging, on the other hand, is discretionary. YOU decide to dig a target, or not. No detector, even the "magic" Vaquero, can make you bend the knee and work. You will find that jewelry items are far and few between and you will dig a lot of everything else before you find them. If you are a 'beep and dig' type, then you possess a good detector for that style. If you like a little more, but not too much more, you wont have it, now.
You makes your choices, you pays your money. DO the best you can and dig everything. That's what I do regardless of which detector I swing. Good luck and happy hunting, my friend.
