LC-5000 leak correlator with 2 pre-amplifiers — acoustic leak-location correlation system for water mains.
Mid-tier acoustic leak detector with backlit analog meter and a bank of 6 selectable band-pass filters (100/200/400 Hz low-side, 600/800/1200 Hz high-side) plus a Filter-Thru mode for 15 Hz–30 kHz full-spectrum listening. 62 dB amp, 110 dB hearing-protection limiter, 28 hr on 6× AA. Tunable analog filtering without digital complexity.
Top-of-line pinpoint leak detector with automatic DSP noise reduction that filters out intermittent interference (passing vehicles, conversations, footsteps) no analog model can reject. Onboard memory stores up to 250 sound recordings with min-noise-level detection across multiple pipe locations. 10 selectable filters (5 high / 3 low / 2 notch for 50 & 60 Hz hum), IP67 piezo sensor. The right pick for noisy urban environments or when you need to document your findings.

Built-in A/C hum notch filter (transformers / power lines), 55 dB amplifier, 100 Hz–2000 Hz response, 3-range sensitivity, stereo leather-cup headphones. Ships with a short 4" rod and a 4-section 13" threaded rod set.
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.
Compact all-purpose acoustic leak detector — one handheld amplifier with three interchangeable attachments (three-point ground plate, magnetic base, contact rod) handles both survey sweeps and pinpointing. 100 Hz–1500 Hz, 56 dB amp, 2× AA cells for ~30 hr runtime, 8 lb total kit. The do-everything entry pick.
