This probe is long! I was surprised how small this probes packs when broken down for how long this probe is. It is surprisingly light for having so much metal. Easy to put together, just give a toss, a pull, and a little shake and it comes together nicely. I like how it clicks when the probe is secured. I went with the long probe because if I ever have to use it, which I hope I don't, I want the longest one possible. I don't want length to be an issue if someone is buried. I know debris piles can be extremely deep, but with a long probe, depth is less of an issue.
