Built for the deep-drop game: 100, 200, and 300-foot release settings for fish that come up from serious water — tilefish, queen snapper, snowy grouper, barrelfish, and anything else you winch out of several hundred feet. Fish from those depths surface in the worst shape of any you'll release, and they're the ones a descending device does the most for.
Here's the part deep-droppers appreciate: you don't have to send a fish back to the depth you caught it. Recompression does most of its work in the first stretch of the descent, so a fish pulled from 500 feet released at 200 is a fish that finishes the trip under its own power — and you didn't run out five hundred feet of line to do it. Pick the setting using the half-the-capture-depth rule and the Deep's range has the entire deep-drop fishery covered.
The mechanism is the same pressure trigger as every SeaQualizer: clamp the jaw, lower away, and the device opens at the depth on the dial or slightly shallower. That shallow-side bias is deliberate engineering, not luck, and it's explained in plain terms here: how SeaQualizer release depth works.
Saltwater-grade and reusable: rinse after the trip, stow it rigged, and it's ready for the next drop.
