Question for Randy

Well-known member
Randy---I know the variability feature isn't on the CTX but is there a way to adjust to higher Hz on this detector to sound more like the Explorer/Etracs on silver?--I have been experimenting with some settings & have run threshold pitch up to max (30) and at 930 Hz to see what it would sound like.---Is 880 & 930 Hz as high as you can go on the CTX?----I may be mistaken but I thought somebody said awhile back that they adjusted it up to 1220?---If that's so, how do you do that?-----I'm not wanting to change a lot of settings etc. till I get on to the CTX but I would like to adjust the tone (higher) if I can.---- It's fun learning this detector but I've got a lot more questions than answers! :tongue:-----It's sure a lot different than the Etrac.-------Del
 
I don't recall what the exact audio frequencies are, for multiple tone CO on the E-TRAC. But on the CTX 3030, the highest pitch you can have is 1200 Hz, with the lowest at 90Hz. You can change the pitch of the highest and lowest tone in multiple tone CO or multiple tone FE. And when you do, the other tones in that Profile will be "spread" over that spectrum. On all the other Target ID profiles, you can change the pitch on all "bins". Page 37 and 38 explain which buttons to push to accomplish this. Although the example in the manual is for appears to be 4-tone Ferrous, the procedure is the same for all Tone ID profiles. When you get the pitch set to where you think you might like it, you can play back that single pitch, or all the pitches in that Tone ID profile. HH Randy
 
Thanks Randy----I'll work with it some more the way you described.---I have used that play back in the single tone & all the tones but just haven't figured out how to get it (the pitch) adjusted up more.---I'm glad I did a print out of the manual--I've been going over it reading & re-reading it. :)------Del

I wonder if a digital tuner can pick up the frequency on the E-Trac (e.g. on silver) and then you can just try to match that by adjusting the pitch on the CTX?
I have a nice tuner on my Ipad but I no longer have an E-Trac :-(

If you adjust the low side of 50 CO tones to about 400-450 Hz and the high side to 1200 Hz that will shift your tones higher and the silver starts to sound like the E-Trac/Explorer. The higher you set the low side the higher the silver dime range sounds, but it will still max at 1200 on the far right side.

However, it also shifts your low conductive tones so you will have to adjust your ears to the lower conductive tones that will no longer sound like the ETrac/Explorer. Since I mainly hunt for silver in the turf this allows me to cherry pick the high tones that I am used to.

A lot of flexibility with the CTX. This has worked for me while hunting for silver. I also run my gain at 15 so I can hear the depth-- so a faint high tone is close to the Explorer.

Good luck

One of the first edits I made was going to 1200. Here's more good news, I have confirmed the CTX tones have shape to them just as they do on the Explorer as you sweep the target. In fact, there's more shape to CTX tones than the Explorer imo. You can hear both holes in a square tab when swept from the right direction, an open hoop earing sounded open, and a zipper/zipper pull assembly man that gave some freaky shape tones when swept.
 
There's some good info coming up here, I'm glad I asked that question. :)---I'll try those adjustments to get the high side on 1200.--------Thanks guys, Del

Are you saying the left bin is tied to the right bin? I don't understand how adjusting the left bin would affect the right one, aren't they independent?

:surprised:

Great news and thanks for sharing. But sounds like you have some exception ears.
You know, I don't remember anyone really asking about the descriptiveness of the sounds and it is interesting for I always heard the Explorer had better sounds than the E-Trac and now the CTX is better than the Explorer, nice.

Del, I've been thinking about the Variability function, and how it might be best "replicated" on the CTX 3030. Now keep in mind, this is just a theory..... Variability was designed to provide a given amount of separation between the tones. In other words, with the Variability set at the max, the spacing between each pitch change is also maxed. When the Variability was lowered, the spacing between pitch changes was also lessened. So, again, just a theory, it would seem that setting the lowest CO "bin" with the lowest possible pitch frequency, and setting the highest CO bin with the highest possible pitch frequency, you would be simulating max Variability. Conversely, setting something other than minimum and maximum pitch frequencies would be similar to lowering the Variability. Does that make any sense? HH Randy
 
Randy-----I could try that & see what results I get.-----I did as Ron suggested today & set my low (50 Co tones) at 450 Hz and high at (the highest), 1200 Hz.----I of course got good tonal seperation quality between the zinc & copper pennies--the nickel was a "no brainer" (tone wise)----but---there wasn't much tone seperation between the clad dime & quarter-a little but not much.----As to the "sweet silver" tone/pitch it wasn't at all like the Etrac (when set up this way).------I'm in no way complaining about the CTX as it is one great detector, I REALLY like it.---Just miss my sweet silver tone.---I'm not done "fiddling" with the adjustments yet! ;)--------Del

are you using just CO tones or combined FE & CO tones the combined FE and CO tones sound more like the way i have my etrac set up then use the same settings as etrac like gain threshold pitch etc.. as you had on etrac worked for me.
