Hello seeker,
I seen your other post on the Terra forum, It appears you're trying to decide which detector to go with. Nothing wrong with that especially when both detectors are good and it's hard to decide which one to go with.
It would depend what type of detecting you prefer, Both are good relic detectors, good coin detectors and both have the capability of finding gold nuggets.
I myself see the T-2 as being the better detector for my hunting needs "relic," This will vary depending on the user because not all users use detectors for the same reason.
Out in the field, The T-2 has a faster recovery speed which is to the users advantage when searching older areas laced with iron. The signals JUMP out even when it's a piece of a weak signal masked by iron, With the Terra X-70 the signal won't jump out. If you're going to search older areas especially when the site is full of old iron you want a detector capable of peeking between the iron and capable of alerting you instantly.
Very user friendly too, Ground balance has a loud audio which helps the user quickly do a proper ground balance with the fast grab, The T-2 does it for you. The X-70 audio is weak and it's differcult to hear the positive and negative to quickly conduct a proper GB, The T-2 has a much stronger audio.
I guess the only weakness I see, The T-2 needs a smaller coil for searching in tighter areas. Separation is not a problem but I can see a need for a smaller coil when searching areas the larger coil can not fit into, I also believe a smaller coil is needed for gold nugget hunting due to the rocky terrain to enhance the signal of smaller size gold nuggets hidden in areas the larger coil can not enter into.
