Low Frequency (LF)

I have a Radiodetection PXL2, on the reciever it has a LF frequency icon. Can anyone tel me what and how I would use the mood.

You use LF in high congestion areas to keep the signal from bleeding over on to non target facilities.

This pretty scary Murray. I hope you have a shovel and not some type of power equipment.

Short answer: use the arrow keys to select. You really should go here and read the whole document.

This is the sort of stuff that should have been covered in a class before you were ever allowed to have the machine. Good luck.

It's 512 hertz.

The theory and what is reality in the field are often different. Ideally, this freq is for conjested areas, but we've all had circumstances where only high freqs worked in conjested areas.

This freq is well suited for long distance locating. If you connect your 10w RD on a 4" pipe @ 65, you may get almost a mile if conditions are nice. The lower frequencies travel over distances far better and you may get several miles on the same pipe with LF (512).

I have an RD PCM (Pipeline Current Mapper) that only has low frequencies as we are measuring ACCA and ACVG over the length (or segement) of a pipe. It can light up 10 miles of 6" pipe as well as everything else that isn't isolated.

It's just another of the things in your bag of tricks. The more the better.
