Hi! Due to the way that the Greenlee 521A Valve Locator generates and injects the tone on a cable, pinning a definitive depth and distance that the 521A can detect a cable can be a little tricky. The depth and length that can be detected are affected by two major factors: 1. Moisture content of the soil2. Condition of the cable being located (deteriorating, multiple faults, water intrusion...etc.).With that said, under the right conditions, a cable can be detected as deep as 20 feet and as long as one mile. A more real world-everyday depth and distance would be 7 feet deep and approximately 4000 feet in distance. Should you have further questions, please let us know. Thank you for visiting Have a great day!
