SKU: LD-15
High-sensitivity acoustic leak detector built around a neodymium-magnet sensor (10 V/g) with dual-range filtering — high 30 Hz–5000 Hz for surveying, low 30 Hz–800 Hz for pinpointing, plus a 150–180 Hz notch. IP68 submersible sensor with 9.75 ft cable, 80-hour runtime on 4× C cells. SSI's pick when raw sensitivity and audio quality are the priorities.
