BUYER WARNING: Good device: capable of running at high speeds (with the right sensor). One of the few (only?) devices that can reach speeds of up to 50 m/s. BUT the probe is not included. and no cable. The photo is wrong. Just a portable device that costs nothing without a probe. Otherwise it would have been 5 stars. And luckily I didn't shoot more stars. You can only use it with a probe (sold separately) without a cable, since the probe connects directly to the body of the device if you wish. But in this capacity it is only good as a hand-held probe with limited penetration into the channel (and poorly readable output on the screen during the probing).
