Q: Do you have a product that will help protect my DuraSonde transmitter in the pipe?
A: Yes. You can check out one of our Spring Carriers.

Q: Why can’t I buy the FV-10 anymore?
A: Our FD-20 is a great alternative for the FV-10. We decided to redesign our transmitters to help withstand the rugged conditions of locating. Our company is always striving to make our products better.

Q: Does the FD-10 get the same range as the FV-10?
A: Yes it does. Keep in mind that this is a smaller transmitter than the FV-10.

Q: Why am I not getting full range anymore?
A: As with most electronics the stronger your battery life the more performance you will get out of it. So we recommend using fresh batteries for every locate.

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: Can I get the FD-10 in a beeper tone?
A: No. We are no longer making beeper tone transmitters. We have found over the years that it does not allow for a good locate.

Q: Does the FD-10 fit inside a spring carrier?
A: Yes, we have designed most of our transmitters to fit inside spring carriers to help protect it from the rough terrain.

Q: Can I attach the FD-10 directly to my push rod?
A: Yes you can. This is another reason we decided to make the FD-10 smaller. You will need to buy one of our Dropcaps. The Dropcap has a female 5/16-18 threaded end that will screw directly on to a 1/4" push rod. We always recommend adding a little electrical tape to make sure it does not come unscrewed during use.
