No, it will not get "respectable depth" by today's standards. It was great at seeing in and around iron (for ghost-townsy-like conditions), but no, wasn't reknowned for depth. Especially by today's standards.
But go figure, such is the rule for most depth demon machines (explorers, CZ6, etc...) : the deeper your reknowned depths, then the more masking you could expect. Conversely, machines which did well averaging and seeing in/around nails, was invariably not going to be depth demons. This is the usual trade off.
On a different subject (straying from your question, but along the lines of the "compromise" I cite above), the Explorer, IMHO, does a pretty respectable job in junky sites, considering the power-house that it is. Sure, not as good in sidewalk tearouts, ghost-townsy/ruins type sites as various tesoros like that Toltec, but still.... considering the power, a good compromise.
