Q: How do I calculate depth?
A: To calculate depth you will take the distance in inches between your front and back nulls and then multiply by .7. An example would be if you measured 50 inches between your front and back nulls then you would multiple 50 x .7 = 35 inches.
Q: Can I use this receiver to locate in cast iron
A: No. The Ardy is only used to locate in nonmetallic lines and septic tanks. It locates with the 223 KiloHertz frequency. This frequency is too high to penetrate through metal. We recommend looking into the Ferris Analog Receiver or our Digital LineFinders that all have the capabilities to locate using the 512 Hertz frequency, which is perfect for locating in cast iron.
Q: Can I use any other Prototek transmitters with the Ardy?
A: No. The Ardy can only locate using our 223 KiloHertz ATP-12 transmitters.
