Re: Profiler 400

Nope. Allegros are more useful, and relatively cheap on eBay. Some use Archers or Recons, I prefer having the keypad. And two serial ports on the older Allegros still comes in handy. You can hook up an external GPS to the Recon. Profiler should connect to Recon by BT, which leaves a serial port for ...

Re: Profiler 400

I have a faint memory that this happens when the Recon ran out of storage space. Is there plenty of room on the device? Maybe you can save data to the SD or CF card.

Re: ERT under high voltage lines

Some utility poles/pylons leak line voltage down the ground wire. This messes up the apparent resistivity calculations. In my experience, about 1 in 10 poles or pylons are leaky enough to mess up resistivity measurements, but utility companies don't care about such low levels of line loss.
