[QUOTE="mbasko, post: 176553, member: 4485"] If they wanted to compete with the TDI they would have re-released the SD2200 series but with it restricted to reduce depth. :lol: The discrimination on them is about as reliable as any other discrimination on any PI detector. Unreliable at best & last resort for gold detecting in my opinion! About as reliable as trusting tones. I've dug speccis that I swore were going to be nails, small tin that sounded like lead or gold & even had a porous piece of gold make the GMT grunt "iron". Solid gold & lead might give fairly predictable signals. Unfortunately not all gold is solid or predictable. Is the 2 machines design fault you speak of finding too much gold? They both do that pretty well :P The TDI might do some things better than a 4500 but on our goldfields I'd back the 4500 all day everyday. No mods required! [/QUOTE]
