SubSurface LC-5000 (4 Pre-amp)
LC-5000 leak correlator with 4 pre-amplifiers — expanded-coverage variant.
SubSurface Enigma 3 Hybrid
Enigma 3 Hybrid kit — 3 standard loggers, 3 hydrophone loggers, 3 hydro sensors, 3 hydrant caps, data transfer case, and storage case. The complete toolkit covering both contact-acoustic and in-pipe hydrophone deployment in one case.
SubSurface LD-18 Leak Detector
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.
SubSurface LD-20 Leak Detector
Pinpoint acoustic leak detector with digital display, 900 V/G sensitivity, and eight selectable high-pass / low-pass bandpass combinations (100 Hz–5000 Hz range). Includes Android smart-phone app for location logging. Direct successor to the LD-16 on SSI's 2026 lineup.
SubSurface PL-VF10R Pipe & Cable Locator
Lithium-ion rechargeable version of the PL-VF10. Identical 10W locating capability with 10.8 V / 10 Ah Li-ion transmitter pack — 2 lb lighter than the alkaline-powered PL-VF10 (6 lb vs 8 lb) on top of the recharge-cycle savings. Receiver 30 hr continuous runtime on its own Li-ion.
SubSurface PL-VF10 Pipe & Cable Locator
Flagship 10W transmitter version with 8 standard active frequencies (adds 815 Hz, 65 kHz, 480 kHz) and 12 total receiver-side. More transmitter power couples signal through high-impedance targets and long cable runs; additional frequencies handle congested utility environments where the VF3 runs out of options. Same 1"–30 ft digital depth, peak/null modes, and directional display as the VF3.
