Minelab CTX 3030 Settings by Ron

April 8th, 2015

Rye Patch Ron

When one buys a new detector it takes time, patience and experience to get comfortable with your new machine. It helps if you buy your detector from Gerry at .  Gerry will take the time to help you and does have one day classes for coin machine detectors.  That being said after you are own your own and no one is standing there beside you telling you when to dig or how to adjust your machine life gets a little more difficult. When I started using the CTX 3030 I tried different settings and combinations of those settings. Now understand that no one’s settings will work in every situation. We have to learn when and what to change for the area you are hunting. EMI and wet soil can make a difference on a spot we are working. Say you are hunting under a power line next to the area, there is going to some interference. So you must remember to run your noise cancel (which I may do several times a day in that situation) to get your machine to run at it’s best. Setting the sensitivity to high or low will affect performance. You can run auto ground balance and not worry about that part but I do not unless all my targets are shallow and the ground is not mineralized. I am going to do a video  on how I set up my machine in the near future but for now I will share my settings here. Now understand this is NOT the only way to run your machine it’s what I like and works for me. I do run a tone  modified coin mode with the settings below. The tone settings are what I like they do not effect the depth.

Ron’s Program


Coin #

Pattern 2 All Metal

Audio Mode: Combined & Ferrous Coin

Response – Normal

Recovery Fast – Off ( run fast if you are in heavy iron but you will loose depth)

Recovery Deep – On

Seawater – Off

Target Separation – Ferrous Coin

PinPoint- Normal

Volume Gain – 30

Threshold Level – Just audible

Volume Limit – 20

Threshold Pitch – 15

Sensitivity set to manual. Start at 20-22 area and increase until your machine gets a little chatty then back it off 1 or 2 numbers. (Sometimes it will have to be less.)

Auto sensitivity Level– You can use Auto and if I do I run +3 but it does not go as deep most of the time but your machine will be somewhat  more stable and give more consistent VDI #’s.

Ground Balance – Off

Noise Cancel – Auto

GPS – Off or on

Hope this helps some of you on your quest.
