2/17/23 Report - Summary of Equinox Conductivity Tests On a Wide Variety of Types of Objects.

Written by the TreasureGuide for the exclusive use of the Treasure Beaches Report.

I've done a lot of testing with the Equinox 600, looking at the conductivity numbers.  Today, I'll gather the results of various tests I've conducted to see how it all fits together.

I'll start with some of the most common targets - ,modern coins.  Here are the target IDs and conductivity numbers obtained for the Ace 250 and Equinox 600 metal detectors.

Next are the Equinox numbers obtained for a broad variethy of targets including a small and medium size old reale, odd small piece of copper, silver cross, silver rings, and an odd piece of copper alloy.

Next are a few gold jewelry items.

The items with higher karat values produced higher conductivity numbers.

Now for some silverware.

Notice the fairly difference between the sterling fork and spoon.  

Here are some complex targets - watches.

Now for some more variety - mixed tokens.

So the tokens ranged from 14 - 26

More recently I looked at some coins that you might run across, but not real often.  First, I compared silver and clad half dollar coins.

Next I compared  silver and clad dollar coins.

And finally, a gold coin was compared to a silver Kennedy half, Peace dollar and American Gold Eagle coin.

Here is a crude inexact chart I made to give a general overall view.

Chart Showing Equinox Conductivity Numbers. of Various Items and Classes of Items.

At the top (black line gold letters) is the range of gold jewelry that was tested.

The black line going from 0 - 40 gives the horizontal scale in conductivity numbers.

The long yellow line the range of silverware numbers, including both steel and sterling.

The red line shows the range of watches tested.

The blue line shows the range of tokens tested.

The short yellow line shows the American Eagle gold coin.

The white line shows the range of 50 cent coins, both clad and 90% silver.

The short grey line shows the Peace silver dollar coin.

The next lack line shows the range of silver reales - one and four reales.

And the last black line shows the range of common coins from nickel to silver and clad coins up to 25 cents.

Looking at the chart, you'll notice several things.  For example, notice how many items of various types overlap in the 15 to 30 range.  The sample of gold jewelry items has a fairly low midpoint compared to many of the other tested classes of items.  The gold coin is up there and the silver dollar is near the upper end of things.  Some junk items will be up there too.

Also remember that depth and electrical interferences can cause inaccurate conductivity numbers.  And position of the item can change the numbers too.

Good hunting,
