First, a few of my ...
Personal Opinions
* It is possible to buy a detector that lacks the type of operation you need for success, so know what it is you plan to achieve by considering the types of sites you hunt, targets you are looking for, and anticipated trash to deal with.
* It is possible to buy too much detector. By that I mean one that does more than we need it to, or is too complex for many users to learn and master, or even achieve the results attainable by a lesser-priced model.
* It is important to have at least two search coil. A standard or larger-size coil for occasional use to hunt wide-open areas (beach, plowed field, etc.), and a smaller-than-stock search coil for the bulk of your metal detecting (to work in and around brush, building rubble, metal structures, or work in and around dense trash).
* It is easy to buy a detector that is too complex to learn or master due to too many adjustment features.
* It is easy, and wise, to own at least two models, and often times the lower-priced model might serve as the #1 detector for most hunting needs, and the more expensive model actually becomes a 'back-up' to the more basic type model.
From the above let me share a few personal examples with you.
a.. My #2 Detecting Buddy ONLY hunts old sites, such as ghost towns, homesteads, stage stops, old railroad sidings and depot sites, and other non-urban environment. She ALWAYS uses a minimum Disc. level to just reject iron nails. She does NOT like visual TID displays because she doesn't use them or need them. She DOES like 'simple' and doesn't want to learn about how to GB a detector or tinker with a lot of stuff. Just keep it simple. She ALWAYS uses a smaller-than-stock coil with the exception being her White's Classic II which only has the stock 8" diameter coil, and works just fine.
b.. My #1 Detecting Buddy started with a White's XLT, which she still really likes and uses, especially after following my lead and switching from the stock 950 coil to the thin-profile 8" coil. She does NOT want to tinker with all of the adjustments, only using my 'Bushwhack' program and she only changes the Pre-Amp Gain when necessary. After I met up with her and her husband, who owned a DFX at the time, I convinced them to join me on a trek to my favorite ghost town to find old coins.
