I bought my first detector in 1994, it was the new, just released XLT. I liked that detector real well, in fact, I used it for 6 years. Then in 2001, the new DFX came out, it proved to be a good detector also. It was more complicated than the XLT, and had more adjustments, and more chances of screwing up the performance. My wife bought a Tesoro Toltec ll in 1994, and we did not know much about detectors, since there was no internet detecting forum. But Darn it that Tesoro would outdo the XLT in the trash. We still have the Toltec, but the XLT and DFX are long gone.
Flash forward to 2007: I started reading Monte's posts on the finds forum, and I got the itch to try all of his favorite machines and the use of small coils. So now I have a 6000 Pro XL, 5900 Di Pro SL and an modified IDX Pro. I have all the coil options for them....4 inch...6 inch......8 inch and stock 950. I am covered for any detecting situation I might encounter.
Get acquanted with the V3i and I'm sure you will do alright with it. I would get the "V" rated 5.3 eclipse coil for it first thing. I really like the 6&1/2 inch coil for about all of my hunting needs. I think the learning period with the smaller coil would be shorter also. I say this because you have a chance of a 'cleaner' signal on co-located targets in a trashy environment
In sumation, Ilike my 6000/5900 as it does everything as well or better than my XLT or DFX. An added plus is not scroling through endless menues to adjust something. My two zincs.
