What Our Customers Say
Absolute game changer for roadside recovery. Fits in my pocket and replaces my bulky old probe. The LED light is surprisingly bright for such a small tool.
I work on HGVs and the 24V compatibility is flawless. It's so light that I don't get hand cramp when I'm probing a massive loom for an hour.
Great little tool for the price. The screen is clear, though I wish the cable was a tiny bit more flexible in sub-zero temperatures. Still, it hasn't let me down.
Finally a tool that fits into the tight fuse boxes on modern German cars. The accuracy on the resistance mode is spot on compared to my Fluke.
Excellent build quality. Dropped it on the workshop floor twice already and it's working perfectly. The UK support team were very helpful with my registration too.
Very handy for quick checks. It's so small I nearly lost it in my toolbox! Highly recommend for any mobile sparky.
