I’d like to introduce Evan Granger as our newest member to Minelab’s Treasure Talk blog. Evan has been detecting since he was 12. Accompanied by his father and mentor, his first major find was a Mason jar cache of Morgan Dollars and other coins left in a post-hole bank. After that, he was hooked and has been metal detecting for over 28 years.
Evan has experience with several types of metal detectors and enjoys using new technology. His ability to quickly pick up a metal detector and understand it has been a key factor to his success. He loves the aspect of recovering and saving lost history.
Evan has given several of his Oklahoma finds to local museums, the Oklahoma Historical Society, the Oklahoma Archaeological Survey, and to other treasure hunters who might not have a chance to see these finds.
Recently, with the addition of the CTX 3030, Evan has helped many new users adapt to the new detector and gained some notoriety for a simple program called “Gonehunting’s Settings”. The simplicity of these settings and his ability to explain them has helped a lot of newcomers to the
CTX 3030. We have had several users claim that with Evan’s help they were able understand and become proficient with their new metal detector.
We feel Evan's experience and willingness to help others will be a boost to the Treasure Talk Blog.

Thanks for the help
The "basics" that helped me was to run the machine in these settings.
If you don't have a "target garden" I would suggest making one. I can help you with that later.
I used the Coin mode with these settings:
First noise cancel whenever you turn the machine on.
Sensitivity-Auto+1 or +2. +1 will be more stable, until you get the machine down and should suffice.
Tones-Multitone. If the tones are too much for your ear, switch to 4 tones it will lessen the "scrambled" sounding tones. Just pay attention to the screen to see if the cursor is being consistent when checking a target.
Threshold-Normally I would have it just above barely audible. Since you are new, having it to where you can hear it, will show you that the machine is working (threshold will be quiet over trash). It will also let you hear how trashy the site is that you are hunting. If the threshold is constantly quiet you might want to find a less trashy spot to hunt, until you "get" what good targets sound like and how they respond. Again, a test target garden will help here.
Threshold pitch- is more of a preference. I had mine at low frequency hum, as to not be overpowering, later switching to high to help with the silver targets.
Variability-29 along with Limits at 29 this should provide the most definition between the targets ID.
Fast-On. This will help to define the targets when in heavier trash. Now this is where most people's problem is. Just because this setting is on, doesn't mean you can swing it like a weedeater. The machine is doing a lot with each swing. My advice is to swing slow as you can stand it, and then slow down some more. You will start to notice more definition between each target when you do. Watch a few videos that show the hunter scanning the targets before he/she digs.
Deep-off This for extremely deep conductive targets and can sometime cause falsing on shallower iron targets. The machine is plenty deep without this setting.
Trash-High. For now.
Volume Gain, at max till you get the machine down. After some time you may lower it to help audibly id deeper targets without looking at the screen.
Trash density- if you are listening to the threshold and it is nulling out a lot then change this to high.
Ground-if you are in an area where the mineralization is a problem, then difficult. If not, then Neutral. If you are not sure leave it in Difficult. The correct setting can sometimes lessen false signals, but don't rely on that.
Now air-testing is in no way a way to judge a machine, but it can help tune your ear to what good targets can sound like. Lay several good and bad targets out with 1 to 2 foot separation and listen. Won't be a real world representation, but it can help.
Finally, go slow, take your time and give the machine's electronics a chance to do what it was built for.
Hope this helps...
