[size=medium]Hi Guys, I'm trying to understand exactly what some of the terminology in the CTX. I've looked at videos on how to turn them on and off and basically where they are located. I got all that...but where can I get an explanation describing what exactly some of these features do? Namely...Target Trace...I know how to turn it on, but seeing a smudgy trail in yellow or red, what does this tell you? You can plainly see 2 targets on the screen...one good target and one iron target, what does the smearing trail tell you. ALSO... Ferrous/Coin....I know this feature helps distinguished between a coin and trash , but How? Is there a video explaining some of these thing, or would someone just enlighten me....Thanks[/size]
