Q: I am using a receiver other than Prototek and I am not getting the range that you advertise on your website. What is the deal?
A: Our receivers are very sensitive, they tend to pick up the signals a little better than others. All our ranges posted on our website are determined with our receivers. We can't guarantee what you will get with other brands of receivers.

Q: Will the HTP-8 work in cast iron?
A: No. The 8 KiloHertz frequency is for nonmetallic locating only. Best used when experiencing a lot of electrical interference.

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: Do the flushable transmitters float?
A: Yes they do.

Q: What receiver do you recommend for use with the HTP-8’s?
A: We recommend our LineFinder 2200 digital receiver.

Q: Do the flushable transmitters fit in a spring carrier?
A: No. They are too wide. Our FD-10, FD-20 and HD-40 DuraSondes fit in all our spring carriers.
