Q: Can I use this with my FD-10 transmitter?
A: Yes. This is the perfect accessory to go with your FD-10. It will help protect your transmitter without compromising its performance.

Q: What if my rodder has a different thread?
A: Please contact our Sales Dept. so we can help.

Q: How do I know the thread on my rodder will match your Spring carrier?
A: If you do not have this information in your manual, go to your hardware store and buy a nut with the 5/16-18 thread and test this on your rodder end. 

Q: How do I know your spring carrier will pass through the same bend as my rodder?
A: The bend radius of your 1/4″ rodder is greater than our spring carrier and 4” sonde combination.

Q: What if I want to attach one of your sondes to my 1/4” Duct Hunter? 
A: We have a battery cap for our FD-10, FD-20 and HD-40 that allows you to thread directly onto your Duct hunter traceable rodder.
