Hi guys im new to this site and just ordered myself a new ctx3030 from miners den and was wondering what settings people use for hunting modern and old coins in parks .Was also wondering i tried to buy my metal detector from reeds prospecting and asked if they would match the price of miners den and they wouldnt budge .I thought if a business was trying to make money wouldnt they try to beat thier competators or is it really easy to sell metal detectors in australia ?.Because i saved about $250 on my ctx buying from miners den .

I used to have a xterra 705 so im guessing this machine is gonna be a little bit harder to grasp .

Gday daniel, im still coming to grips with this machine myself
There are a lot of setting options unlike my previous detectors roll
Coming from the 705 i think you will be ok
The 3030 comes with a preset coin program

This topic gives details on fine tuning that program and its what im using most

Settings = 1001 options

Silver mode and then it is up to you as to Sensitivity / sound profile and many other settings. All depends on teh ground conditions and which coil.

Clay / Sand/ Salty wet sand / other soil conditions all require slightly different settings.

Practice and use some good test pieces and get to know the CTX.

First thing to remember is every preset program is just that, a preset, any preset program can be made exactly the same as any other if the settings and discrim patterns are matched, the presets are basically switch on and go settings. The "Coins" mode is a really good one and should work fine, I use it 90% of the time, I rarely use any of the other presets as for other situations I have made my own custom programs, such as a Pre Dec coin, $1 $2 coin and silver and gold jewellery program. Also a goldies only program and a Pre Decimal only program for extremely trashy sites so I can isolate good targets among high trash conditions.

The settings I use for parks in "Coins" mode are.

Fast: on
Deep: off
Target Separation: High trash if there is heaps of junk or low trash if there is minimal junk.
Tones: Combined
Sensitivity: Auto

As AngerManagement recommended, get some modern coins, silver coins, silver rings to use as test pieces so you know the target ID's that they give, such as $2 coins will be say 12:36-12:38, $1 coins will be 12:39-12:40.

Read the manual, then read it again and again and so on until you understand the menu and related settings. If you think you have changed settings too much and the detector is not performing do a factory reset.

Hope this helps and best of luck with your detector.

Thankyou so much guys for the feed back.Much appreciated so excited to get this machine .May i ask heatho whats your $1-$2 program settings are .I think thats the first thing im gonna do is go goldie hunting smile.Yeh the one thing that worrys me about this machine that i think will be difficult to master is Beach detecting as i didnt do alot of it with my 705 and heard it can be difficult if you dont know what your doing .

Check out my post in Sandta's thread, these are the custom discrimination patterns that I've made, it's only the discrim patterns that are any different, the other settings I use for parks in my earlier post would'nt really change for hunting goldies. These custom discrimination patterns I use are only when there is so much junk that you cant pick out the good targets due to so many signals and if you suspect a good target is among the trash. Using such a tight discrim pattern for general detecting would be robbing you of any potentially better finds like gold or silver jewellery.

The settings I gave earlier are perfect for parks, just look for the target ID numbers I quoted for goldies and if there is not too much junk you'll be able to identify the goldies nearly every time, some aluminium screw caps give the same numbers but that's just part of detecting getting junk as well, though with practice you'll be able to cherry pick out mostly goldies going by the numbers and still detect other desirable targets too.

Beach detecting is pretty easy, luck apart from most other things plays a big part, learning to read a beach is more important when detecting right on the shore or in the water and tidal zone.

Your 5 cent 1207 , 10 cent at 1215 , 20cent at 1222/3 your 1 cent will jump into piece or copper coins will get near or past the silver range , gold ring at 1228 depending on purity , pull tabs for me area round 1218 and your good quality bottle tops will sneak in . Your stainless steel rings - don't know - guys any idea on that?

Is there anyway of telling weather its a bottle cap or a $1 coin because i heard that caps can come under the same number .Thanks for the advice again guys .

Hey heatho i seen your goldie pattern you made and it seems very tight .If i went over a piece of metal in the ground that was in the disced out pattern and there was a goldie near it would the ctx still see the goldie or would the greyed out piece of metal hide the coin ?.

Depends what target separation type you are using and also depends on how close the other piece of metal is. Have a read in the manual about "target separation" on pages 41-42 as it explains it much better than I can, it's quite important for successful hunting with the CTX.

I generally use "high trash" and flick into "ferrous coin" if I suspect a good target is being masked by iron trash.

Only way to be sure is to dig it up. Aluminium screw caps are one of the main types of junk you'll see in my junk bucket, not much can really be done about them if you don't want to miss any goldies.
