  • Ridgid KD-4550 Locator

    Who knows what a error code on a KD 4550 locator breaks down to?
    When we shift from locate to depth we get error, and the # 55.

    We have the unit set right on the proper frequency and mode, and put new batteries in it. This is a new problem on a old gal that has served us well for years.

    Any information would be helpful, Thanks

    My guess is you will have to wait until Monday and ask tech support by phone.

      Had one for almost 10 years before it was stolen a few months ago. Never saw that error message

      Didn't see anything in the manual about error codes.

        Error code #55 on the KD 4550 indicates that there is a problem with the circuit board and/or the keypad. If you send it to the RIDGID repair center, they will determine if it can be fixed and quote the repair for you.

        Before you invest a significant amount in repairing the KD 4550, you may want to consider getting a demo on some of the new RIDGID locating equipment. The technology has come a long way since the KD 4550 and I think you will be impressed with the new features such as the visual display and Omni-Directional antenna technology which makes for easier and more accurate locates.

          if you're interested i have a good working 4550 and a new 4510 that i can part with.

          but as mentioned. the newer units are much easier to work and locate with.

          a great camera locator is the scout and it does 99% of my locates.

          phoebe it is

            I have one and use it daily. I get 55 all the time, there is nothing wrong with it; just the signal is too weak to calculate a depth; either you are not over the sonde or it is too deep. Depth function for me, with the sonde on the mini reel, is good to about 10', maybe 12'-15' but not as accurate, less in cast iron. In plastic to 8' or so it's within inches.
