• How much water is on the Moon and what use is it?

  
  Physics Today News Picks — Authority: 479
  Science : After several decades of controversy, scientists now know that over billions of years, water can collect as ice in some of the coldest places in the solar system. Whether theres enough lunar water ice for future astronauts to drink or turn into rocket fuel, however, remains to be seen says Richard Kerr in ...

  OKM makes only magnetometers and dowsing rods. Both equally worthless in treasure hunting/archeology. The big boys prefer something with big coils and lots of power... http://www.geo-western.com/em/em.htm

  Hi H iiiQ. I have questioned about the technic used for rober c from okm and anybody say nothing about this. I supossed is pulse induction with software and magnetometer too, but realy what it is ? because they say has a range of 18 meteres underground. How is possible with a battery of 9 V in rober c 2003 ?.

  I just found out that another friend of mine is selling his OKM rover for 10,000 euro. He will take a significant loss but I figure its a tax he will have to pay for neglecting his physics in high school....

• Seeing rocky exoplanets

  
  Physics Today News Picks — Authority: 479
  Nature : Exoplanets are distant worlds that orbit stars other than our Sun. More than 370 such planets are known, and a growing fraction of them are discovered because they transit their star as seen from Earth. The special transit geometry enables us to measure masses and radii for dozens of planets, and we have ...

• Re: IS THERE A SOURCE ONLINE FOR INTERPRETING GEOPHYSICAL IMAGING

  
  TreasureNet Forum — Authority: 198
  Different methods look at anomalies differently, and even different manufacturers of the same method might assign or process colors differently. Its sorta like VDI numbers on metal detectors, everyone is different. The best approach is to take a unit and run a lot of tests on known buried targets, fills, and voids. ...

  TreasureNet Forum — Authority: 198
  it would be great if some one could make a vidoe of scanning and interpeting the data and place it on youtube. there is not one vid of magnetometer imaging there. you could be the first.

  I saw one time a 3D representation of a scanned metal box, the shape is distinct (sides are not hazy)and the color(red, like the flesh of a water melon) is also distinct. I also saw the scan result of a void area, the color is black and the sides of the void are distinct and very clear. The one posted above is an ...

  hi you are correct, most scans do show a red spot, this is what I was trying to explain when I was saying that you really need to understand how to interpret, what the scan is showing you, what the company does not tell potential buyers, is that when you scan an area, they make it look like you dont have to do ...

• OKM

  
  TreasureNet Forum — Authority: 198
  Hi gooch. Have you ever noticed that 100% of the scans with the OKM have at least one red  and one blue spot in them? The software is simply amplifying the points with highest and lowest magnetic response. By nature this magnetometer can not ever detect non-ferrous targets. Also by cassbizs oun admission the depth ...
