Non-toneables - When a tone cannot transmit over an item

Three pipes are marked as 8", 4", 8" beside a state roadway ditch.  There is a 31" measurement.

811 only locates with tone equipment.

Due to this disadvantage, 811 locators can only find what they connect their equipment.  They cannot find other items in the area.  What's Below uses equipment that finds anything under it for over 232 feet.  Tone equipment only goes 8 feet below the grass.

List of non-toneables (all detectable by What's Below):

Plastic water and sewer pipes

Fiber-optic lines

Something like a pipe that is a mile long or longer

Cement sewer pipes

Septic tanks

Plastic gas lines

Clay lateral lines or field tile

Cement or rock foundations

Water edge in a sewer pipe

Construction debris

Caverns

Underground streams and rivers


The picture shows a great example of how tone equipment cannot find it all.  What's Below came after an 8" water main (left) was hit by a contractor because it was not located or marked by the water company's tone equipment.  The tone was connected to the 4" water service line instead.  What's Below locates it all !

Ground penatrating radar

GPR has many different antennas to find what is below that can be non-toneables.  However, you must know how deep the items are you are trying to locate...  What's Below has one set of antennas that can locate anything at any depth.  This makes for faster locating.

What's Below has the fastest and deepest location equipment.

You need to find all items in the area you are about to dig.  What's Below can locate it all !  Toneables and non-toneables are found by What's Below.
