Cable length measuring device

Nah.. that's some BS if you have to "use an app" on top of the device... What is it? Just use an fluke meter, do the math formula on the resistance, then bata-bing, there's your length...

Why can't you use a simple measuring tape

That's a neat little tool, never seen one like it!

Distance is calculated using: d=\frac{ct}{2} Where: •d = distance •c = speed of light •t = round-trip travel time of the radio wave

Cable is the kind of thing where your brain rejects it, then the explanation makes it weirder

Nice tool Makes cable measuring super easy
