I just bought one as well. There's so many control options for this thing you can set it for a huge variety of sites. I hope to be able to sniff out winter camp relics that my MXT/T2 have missed but still be able to keep up with them depth wise in sites with scattered finds.
Since it seems there are at least 2 new Racer 2 users maybe watching this thread,,,I will try to give some more insight into what a person may see based on targets,,and some settings adjustments they may use to take advantage of certain situations.
Let's say you want to cherry pick for higher conductors.
Yep,,you can use 3 tone and set your 3rd tone to where you want the high tone to sound off.
Will this get all the high conductors (detectable) in a trashy site??? Probably not.
Allow me to explain,,,first I encourage all new users to get a copper penny or clad dime,,and a pull tab. Place on ground using 3 tone,,with tab and coin real close together and sweep (have 3rd tone break set to 72)... When you sweep the coin and tab,,,listen to the tone you hear. Remove the tab, and sweep just the coin,,and listen. Notice the difference in tone.
You see with the tab and higher conductive coin,,,the detector actually sees both the tab and the higher conductive coin,,,and believe it or not,,,the Racer is actually providing tone on each the tab and the higher conductive coin. But the tone is being cut off on each end,,meaning you are hearing just some of the mid tone (tab) and part of the high tone (coin).
Btw sweep the tab solo and listen as well.
So when a person is out a hunting,,,you hear a solid mid tone,,,this could be a low conductor or actually a pair of low conductors
But if you hear the tone gotten above when you swept the say dime and tab,,,that tells you you have mixed conductivity,,one high and one low.
Now what about VDI,,,in the examples above,,,you will notice,,with coin and tab,,an actual average VDI will be shown on the meter,,,yet the tone ( sounds sorts honkish high low or low high depending on coin and tab orientation and which direction swept.
Now,,,when you are sweeping say the coin and tab,,,with your 3rd tone break set to 72,,, try adjusting up and down,,and notice the affects.
Also a person should notice,,the average will be higher using a higher conductive coin vs a lower conductive coin (( like using a aincoln vs clad dime).
So just by using your ears,,listening to the tone provided with proper tone break setting for 3 Rd tone,,,you can gamble better on which hits have mixed conductivity of commingled nonferrous targets.
Now after doing the tests above,,,pay attention to the average TID provided. Why??
Because next I will discuss using 2 tone and how a person can even use it to sniff out some higher conductive finds commingled with lower conductive junk targets.
In a real trashy site,,a person can use 2 tone,,,the key is dialing down the tone break setting,,,so that the average TID netted on comingled ( high and low conductors) will provide higher tone when swept.
Now this process not exactly scientific but has netted me some decent finds in trashy areas.
This process works better where the typical style pull tabs exists,,not the real big ones.
So basically somewhere around 33-35 on the tone break setting will net the comingled targets of higher and lower conductivity. Solo Nickels here unfortunately will be lost,,,but one could be dug comingled with higher conductor.
Most ring pulls will ring low tone,,foil,and other junk.
A person will dig some junk using this process,,but it will be greatly limited.
Remember even using all the above,,a person can still get the clean hits with more true VDI.
Racer 2 is a nice unit,,,settings do give a person some good options.
Also,,the deep function,,,just remember recovery rate is slowed,,and so should coil sweep rate.
Folks new to Racer 2... Doing the above test will help a person understand moreso maybe what is under their coil--- based on tone(s) and VDI displayed.
Cheers.
