2 box

[Anonymous]

Mr. Eric Foster

What is your opinon on 2 box detectors? (TF-900/TM808 etc.) How do they compare with your deeptstar? I have been told that they would work better on hills/mountains and that they can sweep over the ground better than pulse detectors (reasons seem to vary). Any comments?

Hi Tom,

Don't think Eric will mind me replying with your question about the TF-900 and TM-808, I've been a two-box user for over 10 years. Used several different types and prefer the TF-900 over the rest. The deepstar would work for deeper larger objects but is geared more for deep recovery on the smaller conductors. All two boxes will not respond to the small conductors the Pi detectors can.

Now if you're looking for a neat set-up for deep larger objects then the TF-900 is the best unit of all, Allows you to shift to a slower or faster Autotune Motion mode depending on the terrain. The TM-808 only has one Autotune speed so you're stuck to a consist pace, The TM-900 allows to adjust your pace with using one of the two Autotune speeds "Fast or Slow" as the terrain changes.

I addition the TF-900 with an extra attachment will allow the unit to be used as a tracer to trace underground cable or thin wires, The attachment attaches to the object to be traced which in turns the object into an antenna sending a signal. Attaching a different loop on the TF-900 turns the TF-900 into a wireless receiver and now can be used to trace the object down as deep as 13 feet as long as 100 feet or more and can even trace the end of a broken wire in a house.

Such is the case when a problem occurs with a sewer pipe "Roots etc." a snake is inserted into the pipe and using the TF-900 tracer feature you can follow the signal to were the root problem is located, Then dig down, find the problem and repair the damage without digging up the entire yard ..............The TM-808 can't perform this neat exercise.

HH, Paul (Ca)..Sorry about the long thread,

Paul, I have a TF-900 and love it but I was not aware there were additional accessories for it. I use it alot to find peoples well heads or burried tanks in the ground. Can you forward any info on where to obtain additional stuff for the unit.

Much thanks.

I agree with Paul's response to your question, however, I much prefer a large coil pulse detector over a 2 box for depth. I bought a 2 box and while the advertisements claimed 9feet depth on a large target, the max I could get was 4 feet on an air test of my van. I then talked with others who reported the exact same results with their 2 box detectors. These were all of different makes. I bought a large coil PI detector and I was able to get 8 feet air test on my van. This was a cheaper, inexpensive unit that is no longer being produced. I sold the 2 box. If you are interested in a detector for larger objects at depth, I would look into the PI large coil detectors as well. If you are looking for smaller objects at depths greater than an IB detector, consider one of Eric's pulse detectors.
Good luck,
Boattow

Boattow;

Thank you for your information, that is what I am looking for. As for large coil, are you refering to something like 18" or 1mx1m? (i won't ask how you got 4/8 feet above your van
I guess the next step would be to find a used pi w/large coil. Any suggestions?

Paul,

Thank you very much for all the information. Because of your insight I have ordered 1 and a traveling I will go. If I may be bold enough to ask, periodically check this sight for the many questions I know I will have. Hie to the hunter!

Sure thing Mike,

Please send me your email and with that I'll forward you a picture of the tracer transmitter and the special loop for the TF-900 along with instructions how to use the tracer attachment.

You can call the compmany listed on the manual for a tracer attachment but last time I spoke with Ron they didn't have any on hand. Still give them a call as they may have had more made up since then.

Hi Tom,

Please fell free to ask questions with your TF-900, If you can try to find a Whites TM-800 video which explains how to use the unit. The Whites TM-800 and the TF-900 are of the same design only different name.

Discovery used to made the TM-800 for Whites until they had a fall out, Now Whites has a two box of their own "TM-808" which is not as good as the TM-800 or TF-900...........Since Discovery relied with Whites selling the TM-800 and with the fall out Discovery started selling the TM-800 under the new name of TF-900, Discovery is the true making of the TM-800 and now the TF-900 which is the same unit.

Hope this helps

Hi Tom,
The coil that came with my detector is a 1 meter coil. This detector is a Black Widow made by Analog Systems. It runs on 3 9volt batteries. Similar to Eric, that was a one man company that made a handful of PI detectors but he is no longer in business. He had a higher end detector called a 104-B which I noticed one for sale on Ebay. If you search under "Pulse metal detector" you can see the Ebay ad. I don't know anything about it but there is a couple for sale on www.treasurenow.com that would probably be similar.
Good luck,
Boattow

Well what do you know...I was only partially correct. While Analog Electronics did go out of business, he apparently has re-launched his business as burton electronics.

check with Eric; it is possible to make an orthongal loop,-2 box loop for pulses.
