If you are interested in upgrading you Arc-Geo Logger to Pro it's easy. The cost is $450.00 + your Arc-geo logger if it's in good shape. You get a new pro logger!
Or if you need to log 0-5vdc I can setup a logger to meet your needs.
You also pay shipping both ways. Email me if interested.
How does the logger work? The Arc-Geo listens to the sound from the headphone jack and converts the sound to a number. The louder the sound the higher the number. This number is stored for the sample position on the grid. Then the grid data is downloaded to a computer for viewing.
Do you have to sweep the coil? No. The coil is moved in steps according to the grid sample size. The sample size should be the size of the detection area. For a 2-box you just walk and the logger samples with each step, which is about a yard. For small coils the size of the coil.
How is the grid setup? If you have a 12 x 12 wall in an old stone home and using a 12" coil, you would set the X, Y to a 12 x 12 grid. The logger handles all the X, Y values and lets you know which sample position you are on within the grid as you log. The logger has a menu and is easy to use.
Can you tell where the target is on the plot? Yes! You can see the target position and know where it is by the X, Y position. The plot matches the grid you walked with the detector. You can also see the size of the target compared to other targets on the plot.
Can I use any detector? Any instrument that has a sound output can be used. I used my Minelab GP, Whites, Garrett, Deepstar, Fisher and Tesoro detector so far with no problems.
Can I join the grids together to get a big picture of my site? Yes! You can join the grid together and have a complete grid of the area showing all metal objects. If you use a GPS to mark the grid corners you can go back and walk up to the target you want to dig. to join the grids they have to be the same size.
Can I locate caves and graves? Yes! if you have the older Whites TM-808 and the Discovery TF-900 both have a cave mode that shows changes in ground conditions. Which includes cavities in the ground like graves, tunnels and vaults. Another feature of the cave mode is small iron targets are not detected but non ferrous object like gold, silver and copper can still be detected! Discovery TF-900 is no loner made and the newer Whites took the cave mode off.
How can the logger help me save time in the field? Most people search and dig when a signal is detected to see what that target is. If you have a very large area to search you can spending way to much time detecting and digging each target for days. But if you log that same area, you can look and see which target are the biggest and choose which ones to dig first. You can also return to that site and know where each target of interest is for future recovery. You can walk a 45 x 31 yard grid in 30 mins!
How deep can I detect a target? That depends on the detector you use. Dan detected a 9" pipe casing 12 feet deep using the TM-808 while doing the field test report on the logger. Canon balls, trash dumps and large battle field metals can be seen using the 2-box or a PI detector.
Does the sound output signal make a difference for the logger? Yes. It would be best for the sound to be a steady sound with a raise in sound level as the target is brought close to the coil. Most detector have this setting. A quick sharp beep should be avoided when possible. You want to use the setting that allows the sound to increase like the VCO setting or all metal mode. Most of the large detectors like PI and 2-box have this type of sound output.
Can I use the logger with a small detector/coil? Yes. But the logger was designed for large targets. You can use smaller detectors for house, cave and to grid a target to see better detail if the target is within the detectors depth range. If you want to try to find coins size targets with the logger in a large area, it can show coins, bullet casings, etc and it will take more time. The smaller the coil size, the higher resolution. But at the same time you can do more than one grid at different discrimination settings to see metal types. This is good when cave and house searching or evidence collecting at a crime scene.
Set the detector to ignore iron and see everything else. You will see the shape and size of the object and know the position in the wall. You can see if its rounded or boxed shape or maybe a vase shape. By holding a small metal target on the other side of the wall offset from the target you can see the relationship between the two in a 3d viewer!
The TF-900 has a metal mode and a cave mode. I use the TF-900 for deep targets while ignoring small objects. You can grid a football size field in a very short time and then download the data back at home or in the field and see what's there. Then decide which target you what to check out first! Time is important when the sun is up and the day is hot, you can scan a number of sites and check out the data later. Compared to doing a ground resistivity grid on a 20 by 20 plot, you can grid the same plot in 20% of the time!
Glenn a plumber is using the Arc-Geo Logger with an 18" coil to locate the main connections. Before I had to dig up the yard trying to locate the main connection. Now I just grid the yard and see where I have to dig. It says me allot of time.
The Arc-Geo logger along with a detector can be used to grid crime areas. Grids are already being done, so adding the logger will not be a problem. The added plot will show all bullet casings or weapons within the area. Also the plot can be overlaid with a photo to show target placement if needed in court. By using a GPS for the corners, the crime scene grid can be relocated again if needed.
Targets have been found to over 13 feet in depth using a logger and a 2-box type detector! Here's an email I just received.
Software is free and can be downloaded from the software page!
"Hi Tim, How are you? Equipment arrived safe and sound! Brilliant! Thank-you so much. The parcel wizzed through customs!! Cheers! Well I tested equipment on my garden quickly! Found logger easy to use, worked great! TF-900 A little harder to use! but able to set it up to get some results! placed some objects on my lawn (Anchor, mild steal bar, steel bearing puller, aluminium set square) and did a scan! (See attachment!) Great! Thanks again for great Speedy service! I look forward in sharing my adventures with you and other Treasure hunters on the forums! All the best, PM. Here's my first plot!"
Glad to hear it!
Just a quick note I have the logger up and running and have done 3 plots into the soft ware VERY impressed. I set up using the little Bounty hunter 505 pro with 4" coil. Used a test grid like you do. Excellent results. I plan on using this set up for re-bar and fine searches. DC
I have managed with Tim Williams site and advise of others to perform my first grid and scan. I am elated and excited to learn more about this technology. I did a grid scan of only 12 feet by 12 feet. I was trying to see how this imaging software would pickup among other things my septic tank of which I knew where it was buried. The software picked the septic tank up in great detail. I have not learned how to tell how deep a target is buried yet but I will with more test and more test. This is the most exciting thing I have done since I first started metal detecting about 39 years ago. I am loving the hell out of this machine. Thanks Tim and thanks for your support and help. Got to go test now bye. By the way I found another target while I was doing the scan for the septic tank. It had me puzzled at first then I realized the TM-808 had picked up the hitch on my mobile home on grid 1-2 the septic was on grid 2-3,4 also 3-3,4. Now if I can find treasure by accident just like the hitch. Again thanks, Tim.
First trip out went well but the area we hit has many trees and was very steep. You could hardly walk with no gear let alone a detector or logger and 2 box. I will be out tomorrow again and this spot has a gentle slope with minimal trees so I will post some pics of my gear and let you guys know how it goes. I had not been to the location prior to that or I would have passed. I do know the area for tomorrow so I can make a nice plot and see some results. The small plot I got in on the hill resulted in a small screwdriver from about 3 ft down. not bad but I want to see some gold! I also want to point out that the screwdriver did not hit on my DFX nor did it hit on the 2 box as a stand alone unit. No tone was heard at all. But hooked up to the logger it showed up as a very nice target. So far I am very pleased with the results of the Logger.

How the loggers work? Field test report on the Arc-Geo loggers.
Since the field test report and advice from Mr. Woods, I have installed a headphone jack and 2 tones for end of each row and 3 tones for complete grid. Dan found that the depth of the casing was 13ft.
