Have you tried upping the sensitivity on the 75 GP? If in doubt in discrimination I go to single tone, in all metal no changes but run it at higher sensitivity setting and the TID will usually come through more repeatable....some sites you can't do this the ears will bleed running above 80 all day but as soon as the TID flashes through you can crank it up as high as you can handle and get some extra finds....Many of my thrippys have come out this way...Might be worth a try next time your out with deus to compare. :Y:Goldpick said:Unfortunately the T2 and Fisher F75 have never been hugely popular here compared to say the F75 in the US, or the T2 in the UK. They do have a fair learning curve, maybe a bit too much for some, and the ever changing dealerships offering such detectors in Australia certainly hasn't helped their sales here either.
I personally own an F75, and I must say it hasn't grown on me like some other brands/models have, although it is a quite deep seeking VLF, even with the regular version without the additional Cache and boost settings. Probably the biggest disappointment for me was the delta pitch tone setting (99 tones). Thought it might be similar to the fulltones setting on the Deus, instead found it doesn't flow nice and smoothly from one tone to the next as on the Deus. Much prefer the 2 tone option with VCO, though it can be a bit of a handful when used in iron infested areas. As mentioned above, the sensitivity control is not like that found on many other detectors, even when set on "0" you are still able to detect shallow targets. Having various thresholds on the senstivity setting makes for a fair bit of experimentation to achieve the perfect setting for any given area - certainly not as forgiving nor complicated as many other detectors.
Either way, the main reason why I purchased mine was for the more simpler task of locating deep targets on relatively junk free ground, something it has already proved itself to very competant at. In the meantime I'll leave the more junkier/iron infested areas for the Deus, having more confidence with that particular detector in such areas.
