Hey LowBoY,
From what I can gather in Europe, the V3i isn't that popular. The E-Trac is very popuar and so is the Omega. The Deus has really taken over a lot of E-Trac sales in the UK and XP detectors there are quite popular in general.
There are some forums in the UK, like Rogers Relics, but you have to be a member to read the messages (unless a google search might go around some of that.) It is really different hunting over there though. They mostly hunt plowed fields though some hunt pasture, which is close to hunting parks as far as the ground in concerned. They really like those small thin hammered coins. I have found a few but mostly they are battered looking and don't do much for me but to each his own.
Really looking forward to that new Fisher CZ. I'm planning on sticking with my E-Trac till then, unless my back can't handle it any more but that swingy thingy helps (though don't like strapping in in order to hunt!)
Regarding the V3i, I really wondered why the E-Trac and CZ's did well in iron mineralized ground but not the V3i. I came to the conclusion that the GB is super important with the V3i and even more than that I think the energy being used across 3 frequencies and not 2 affects it's ability in iron mineralized ground. The CZ has a regular ground balance as far as I know, so it can't just be the GB of the V3i that caused the results I saw, so I chalk it up to 2 frequencies and not 3... Hmmm, wonder if the DFX with 2 would be better?
