Leak Detectors

Why buy from Bench Mark?

You can shop our vast supply of survey equipment to find everything you need to get your job done.  You need a tough, reliable, and simple solution.

We adhere to a commitment to supply high-quality products to our customers, and we can speak to the quality and durability of every leak detector we sell.


All of our leak detectors are intuitive to use and easy to setup. The entire system is built around the idea that anyone can use them.

All of the SubSurface leak detectors operate on the same principal. When a pipe begins to leak it creates a sound that is transmitted through the ground. By touching a set of transducers to the ground those frequencies can be picked up and are displayed on the locator.

All of our SubSurface Leak Detectors are backed by 7 years of warranty. We want the detector you purchase to last you for years to come.
