Found one of these at a local resale shop. I know this is an old dog, and probably a bit much at $35, but after using motion discriminators all my time in the hobby, just had to live the experiance of learning to use a tr. After cleaning it up, fixing a loose coil rod problem, intermittant wires in the coil connector, & picking up the required batteries and packs from RS, found it does basically work and find metal. Have a user manual from Keith Wills on the way. Major problem, expected after reading forums and such, is tuning stability. Deceided the best use of the meter was to set the tune to basically split the meter straight up and down, ferrous to the left and metal to the right. Soon as the coil is moved a ways though, it quickly goes out of setting, the needle drifting off to left or right, and have to constantly re-adjust it as the coil is moved. Just wondering if anyone has heard of a manual retune button or auto retune circuit that could be added, or if this is just life with the old tr. Of course, I realize I could just be setting it up or using it wrong. Also, all the knob functions are clearly marked, but there is a slide switch on the front of the case near the coil connector that is unmarked. Any Idea what this does?
Thanks,
Kevin
