This probe has a difficult time retracting when cold. The last section, near the green handle, has an inner shaft which extends out and puts the final tension on the cable running the length of the entire probe. I have had this junction freeze up on me several times. A probe is a piece of equipment that should never fail, and this one consistently does not work for me. I have also had several others try it with similar results. During a multiple burial rescue simulation this past weekend it also did not deploy.
