Lightweight and effective, but not very durable

This underground utility locator works very well and is super lightweight. However, it is cheaply made and not very durable, so it cannot withstand rough use such as chipping dry dirt off an excavator or being used as a weapon. Despite the lack of durability, it performs its intended function effectively.

Pros
  • + works very well
  • + super lightweight
Cons
  • − cheaply made
  • − not durable

Worth the money for occasional property use

Despite the high price for an individual property owner, this locator proved worth the cost. It is easier to use than a previously owned model, especially for electric lines, thanks to an inductive connection with an included clamp. The rigid handle and pickup foot make it more precise and easier to use in tall grass or brush. After some practice, locating wires became straightforward. Depth measurement is fairly accurate and easy. It works well for running water and electric lines that intersect existing lines.

Pros
  • + easier to use than a previous model
  • + inductive connection with included clamp
  • + rigid handle and pickup foot for precision
  • + works well in tall grass or brush
  • + fairly accurate depth measurement
Cons
  • − high price for an individual property owner
  • − takes some practice to get used to

Poor performance for the price

This locator struggled to detect a known 220-volt line from a garage, and during testing its readings were inconsistent. It was returned the next day for a full refund. At roughly $1,500 after tax, the performance did not justify the cost.

Cons
  • − Could barely locate a known 220-volt line
  • − Inconsistent readings during testing
  • − High price for the performance
