Cable Detection EZiTEX t300xf Signal Generator
The more powerful, 3-watt version of the excellent t10oxf, the Cable Detection EZiTEX t300xf has been specifically designed to complement Cable Detection's range of 'xf' cable avoidance tools. The 'xf' stands for the two additional low frequencies that can be emitted by this genny in order to allow the user to trace signals over longer distances.
We would always recommend using a compatible signal generator with your C.A.T. - it's impossible to make use of more than a fraction of a cable avoidance tool's abilities without a signal generator. Yes, you'll be able to pick up those services emitting a strong power signal but you won't be able to pick up anything metallic that isn't. That could include water mains, gas pipes and so much more.
What's more, in order to get the most out of your xf-series CAT, you'll really need to use an xf-series signal transmitter like this. Yes, the t300xf can emit the low frequency signals needed to trace over long distances, but if your cable avoidance tool can't pick them up they won't do you much good.
