Outperforms all the others when it comes to sensitivity on smaller gold chains etc thanks to the 12 kHz Circuit, ALSO enjoyed by the Little Side Kick and my preferred rental for lost jewelry, THE COMPADRE which runs circles around the Aces and Prizms when it comes to Fast Filter Response and Gold Sensitivity.
PIs, like the Tesoro Sand Shark are quieter but lack the Discrimination and Sensitivity on Diamond Tennis Bracelets etc.
At Lake Tahoe, using the Tiger Shark, I located three rings including a Platinum Ring, along with a nice Thai Movement Armitron Watch all in one day.
The Rub: Lake Tahoe is Fresh Water but heavily mineralized-black sand. This caused a shift in the phase angle so Nail were a bit more difficult to reject at low Disc settings.
The WISH: Bring back the NON-Motion Filter TR Disc found on the older Stingray II.
Regarding Depth... competitive, depending on the ground conditions on coins. On Jewelry, well the 'Others' in many cases won't even detect certain jewelry items an inch away.
