180 meter number chart

[cdsmith46]

Can anyone point me to a place where I can find the number chart for a Minelab 180 meter? The sunray dti's would also be acceptable. Just trying to get a general idea of the numbers and their reference ponts...
Thanks ahead of time...

Here ya go. I did this chart using the Minelab DigiSearch meter. After comparing some targets on my GT to the other older charts floating around I found that they were often way off in terms of what my GT/DigiSearch meter was telling me. I used noise band 2 too, as using band 2 is said to more closely match the older Sovereign charts while band 1 will at least affect mid conductivity targets like nickles, raising them a bit. All targets in BOLD are my personal readings, while the ones not listed in bold are numbers from other charts that I haven't confirmed or corrected yet. There is also tab and ring percentage info in the chart that can be referenced in the Splitting Hairs On Rings thread, which a link is provided to in this thread on the ID chart. On the next version I'll be listing ring percentages through certain number ranges directly to remind somebody in the field just where their best odds of digging a ring are.

This chart is still a work in progress. I have various types of wheats and indians I need to scan in as in particular some indians like fattys can read much lower. The junk targets at the top where compiled using an extensive collection of those targets a friend and I had dug over a large span of time. I must have spent three hours just scanning in things like a collection of various high/low/medium shotgun brass and such, and tried to relate the most common target traits to things like this to give people better clues on how to ID them.
