Does using a lot of discrimination hurt detection depth on the Explorer? I know many of you hunt with less discrimination and just decipher the tones, but aside from the masking that could take place, would using a lot of discrimination at times hurt detection depth? Thanks, Ray.
 
Hi Ray
If I am at a new site, I will start out with an advanced programs that I have loaded from the SAVE menu, as I find trash I knock it out via the LEARN menu using the small cursor and the the reject option, it can be very specific.
If I am hunting for coins, I will go to advanced and load a saved program in-which I have scanned my collection of new and old coins. The Explorer will reject all other targets, it will learn to accept or reject any target that is scanned accross the search coil.
What has helped me alot is Andy Sabisch's book Mastering the Minelab Explorer XS & S. I also bought a DVD on the Explorer Training Presentation. TB
 
Ray,
In non-mineralized trash free ground you can get the same depth with discrimination as without. If a target is hitting in a non-discriminated out area of the screen it will sound off even if you have the rest of the screen blacked out.
However, the deeper the target the more likely it is to be masked by mineralization or another target, so it will not hit in expected area. If you are running your sensitivity hot which is needed for depth even under good conditions a target will often bounce around the screen. Maybe 1 to 2 or 1 in 10 swings it will hit in the expected area. This means that you have a 50% to 10% chance of hearing it for any given swing over the target.
In a nut shell if you have lots of discrimination you are more likely to only find shallower targets that give a stronger signal and are less affected by mineralization and co-located targets. There will be times in cleaner ground that you will still get the deeper ones, but the odd are working against you.
Hope this helps,
Chris
 
Stands to reason if unit is discriminating more its working harder and may cause you some loss of depth depending on your ground mineralization and of course how trashy the area is..Just a fact of life and many units advertize for superior depth use all metal which presnts a noisy mode but does give more depth. So I guess we are back to give and take and many excell in a noisier mode and thats where tone ID on an Explorer excells...
 
No matter what mode I am in I hunt using tone id, then check screen to decide if I want to dig.
 
Find you a new site, say an old homestead. Run with Iron Mask at -10. Grid the site going at semi-slow to medium speed and dig all targets that register near the areas of targets you are searching for.
Then go back over area with a grid pattern running say IM-15 or IM-16 Ferrous and do the same. You probably won't find a whole lot if you've been thorough but if you do then you may want to stick with the lower disc. As it probably suits you or your ground better.
HH,
Greg
P.S. The Explorer is a master at sucking out targets admidst trash and does excellent at not losing much if any depth while running with high discrimination.
