Summary: The Tracker S is identical to the Tracker3 with the following exceptions:
As with the Tracker3 and Tracker4, the scan (aka " big picture") mode is excellent, the indication of a close proximity multiple-burial is nice, and the signal suppression seems very functional (albeit limited). And although the two-digit display, the shorter reception range, displaying two people when there are multiple transmitters rather than displaying the number of transceivers, and the small on/transmit/search dial are less than ideal, the Tracker S is a solid contender.
The lower-priced "S" model targets price-sensitive purchasers. The savings of only $35 (at the time of this writing) for a transceiver that you can't update, has a smaller display, and lacks a motion sensor probably isn't a bargain. If you are considering both the Tracker S and the Tracker3, I'd lean toward the Tracker3. And I would seriously consider the Tracker4 which has more glove-friendly controls.
