I'm thinking of getting a used Etrac but wondered if its better to wait until the EQ 800's are out ? Don't know if they will perform as good as the etrac but they certainly are lighter which is a big plus to me !
Lets gather some information first. What type of detecting are you planning to do parks, home sites, fields, relics, beach? What area of the country do you live in, what's your local soil mineralization like?
The EQ has many new features that are attractive but lets consider the one that could be a game changer. Minelab is claiming the EQ will have more accurate target ID at deeper depths, if true that may be a game changer. The only way to do that is to better filter out the soil mineralization that's masking deeper targets. If you do that what just happened...depth just increased. Then if you consider sites have been beat to death with Explorers, eTracs, and now CTX's over the past 18 years a machine that can suddenly reach even 2 inches deeper with a target ID may re-open those sites, if deeper targets are down there of course.
Drop a silver dime into a plastic milk jug filled with water, that's an air test. Now put 1 drop of food coloring in the water, this represents soil mineralization. The detector can still see the dime so far so good, low mineralized soil. Add a few more drops, its getting more difficult to see the dime. Now pour the whole bottle in, the dime is no longer visible. This is the effect of soil mineralization and the more mineralized it is the quicker the target is swamped by soil mineralization and is no longer detectable.
And its not just max depth but target size. Half dimes, 3 cent silvers, $1 golds already due to their size are more difficult to detect at depths a dime/cent is still detectable. It will be interesting to see what the EQ can do based on target size vs the FBS/FBS2 machines.
