FS: Discovery Electronics TF900 Pipe Trace Unit

Discovery Electronics TF900 Pipe Trace Unit. $400.00

1. Special 73.5 khz Search Coil, that is attached to a TF900 Detector.

2. Control Box ie. Transmitter with color coded leads + Red - Black with Clips and a set of Instructions.

This Sale DOES NOT include the "TF900 Detector", this sale ONLY Includes the "Pipe Trace Unit".

The literature says the unit has a Depth range of 6'-10'and a trace distance from the Signal Injection Point of 200' to 300'. In my experience you would NEED a GOOD set of Headphones to achieve the distances and Depth. I used a unit in 2000 to trace 1 mile of 4" to 3" to 2.25" STEEL from 2' to 6'Deep. I used the instructions to preform Depth measurements and they were accurate to within 95% of indicated values.
 
These tracer attachments are so rare, I've got one loaned out at the moment.

Great for indrustral purposes or personal use, will pay for itself for sure!

Will also work with the older White's TM-800, Not TM-808 only the TM-800 or TF-900.

Thanks Paul, I didn't know that they would work on a White's TM-800. I guess that would make sense as Discovery made the TM-800 for whites off of their TF900 till they went out of business in 99 or 2000.
I have another one but want to keep it for resale value for my TF900, If I decide to sell it in the future. I have some projects to do with it and the ArcGeo Logger I have. I'll use the TF900 first in ground cancel mode and then switch to TR mode to pick up places that have been disturbed in the ground with different mineralization. Then I'll switch to a Carl Moreland Magnetometer and log the area with it. Then switch to a SD2200V2 with a 24" UFO coil. I may have the 36-40" Blanket coil made, for the SD, by then and use it also. Then take the maps of the area and overlap then to see which will give the most info.
