It reaches usable live sonar imagery down to roughly 1,000 feet with a 120° x 8° beam pattern and a minimum 10 frames-per-second refresh rate, aimed at vessels fishing 200 to 1,000-foot depths who want real-time, moving live sonar of the water column around and beneath the boat rather than only a historical trace. Buying the transducer alone typically suits a replacement scenario, or an installation where the mounting hardware, cabling, or display module is being sourced or reused separately from a prior setup - professional thru-hull installation is still required either way. It needs pairing with a compatible Garmin chartplotter or sonar black-box module capable of driving Panoptix live sonar to actually display the imagery it captures, since the transducer itself has no screen or processing of its own, and the bronze/stainless-steel construction is identical to the complete PS70-TH listing since it's genuinely the same transducer hardware, just packaged without extras.
