Q: Can I use the flushable transmitters on the end of a sewer machine or push rod?
A: We do not recommend it. Using the flushable transmitters in this way will void any warranty. We do recommend many of our other DuraSonde transmitters along with a spring carrier for this type of use.

Q: Can I use the ATP-12 to locate in cast Iron?
A: No. The ATP-12 is only for use in nonmetallic lines and septic tanks.

Q: Do the Flushable transmitters float?
A: Yes they do.

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 multiply 50 x .7 = 35 inches.
