Most helpful review for Whites TDI SL

TDI SL, where's the beef?

I have used all three models of the White's TDI and still have a couple of units. The SL works, but disappointingly nowhere near the depth of the other two models. Have have both the 7 and 12 dual field coils. The 7 inch was just plain sad on this detector, many of my VLF detectors are more responsive.

Do not get me wrong, I use and have many White's fine machines, but this one needs much more to be a winner in my book.

Most helpful review for Fisher Gold Strike

Is the Gold Strike worth it... ?
I have been using the Gold Bug 2 for several years now and I thought I'd upgrade to the newer Gold Strike from Fisher. At first I thought I had made a real mistake but found that the biggest part of the problem was the operator... me...
The Gold Strike has a much more difficult learning curve than the Gold Bug 2 but if you put in the time and effort to learn the detector it works quite well. I took both detectors with me on a trip to central Az, and ran them against each other in a field test.
Result... over the course of 3 days, every time I detected a nugget with the Gold Bug 2 the Gold Strike would also find it before digging, The Gold Strike found 2 moderately buried nuggets that the Gold Bug would have missed because of hot rocks.... The Gold Strike did find a lot of Trash that the Gold Bug ignored but the final tabulation was ..
Gold Bug 2 --- 5 nuggets (very small to medium)
Gold Strike -- 7 nuggets (very small to medium)
Total gold ... about 4 Dwt.
If you take the time to learn how to use the Gold strike, it is a very good machine. For a first Detector I wouldn't recommend it but for someone willing to take the time to learn how to adjust it properly, It is worth the effort.
