We should all use detectors that we are comfortable with and that work for us and our needs, and for the ground mineral environment we hunt in.
I know I had one [size=small](only one that I remember)[/size] Silver Sabre Plus that worked reasonably well, and I recall a phone discussion I had with Jack Gifford at the time about them. I was a Tesoro Dealer at the time and had more come in, or some I checked for folks who bought them elsewhere, that just didn't work well. Threshold issues, and Ground Balance issues, especially, and overall they didn't handle coil swapping as well and the original Silver Sabre. That was mainly in Utah and Nevada and some western Wyoming sites we hunted, mainly desert and mountainous ghost towns or homestead type locations.
I preferred manual GB models most of the time, anyway, but passed on the preset Ground Balance SS Plus for the original SS.
I am with you on liking the comfort and feel of the under-slung housings, both the early metal types as well as the ABS plastic housings used on the Bandido, Bandido II and Silver Sabre II.
And I only went to a bigger-than-7" coil now and then in more open areas, and favored the early white-colored open-center 8" coils over the latter released thicker brown 8".
