Just curious........... Depth question

[Elton]

what do you use for deeper depth in old parks for Silver mixed in with junk and clad ???


What is your thoughts on Auto sens +3 ?????

I used the stock COIN program and pattern most of the time. The key to depth was low & slow. I scrubbed my coil over the ground. The stock COIN pattern seemed to do a pretty good job of eliminating most junk.

I tried manual and was never happy with it other than checking a target I had already found in Auto +3. In manual I seemed to get a lot more falsing from iron and even had a few good coin signals breakup after switching to manual that were good in Auto +3.

I always stuck to AUTO +3. The stock coin program is good,But in open ares with little trash I run quick mask at 23 as deeper coins ferrous numbers go higher. I read about this in Andy Sabisch's book and it is true. I think he even runs it a little lower at 28? It is a good book and worth the price if you don't already have a copy. A lot of good tips for E-trac and Explorer's.

I try to run mine at 27 to 30 manual. Been having good luck at 30 at a few spots.

I have recently been setting mine on auto 3 and seeing what the ground is reading then switch to manual and set that number manually. I use the stock coin program or a TTF program that was shown to me by a Etrac veteran in the area discing up to 20. Setting it manually seems to make a difference in depth. I do not get much falseing.

Sweep speed is critical in trashy parks new or old. I noise cancel then start in Auto +3 and raise it according to the ground. If it will go auto3 and run in the low 20's I will usually be able to run close to sens 30 without "over driving the head lights" and listening to a bunch of falsing and chatter. I often encounter ground that only recommends sensitivity of 10 or 12 even in auto3 and then getting it even up into the 20's can be a chore. If I can find a respectably deep target , 7 or 8 down , I experiment with both the noise cancel channel as well as the sensitivity to see where I get the best tones and TID and use that as guiding light.

Gotta slow way down in trashy parks and listen for those faint squeaks of silver and then dial them in.

I think auto 3 is a great starting point but I wish there was an actual ground reading number generated by the e-trac but , unless it's one of the numbers in the hidden screen , the sensitivty reading is as close as we get. It would be a great time saver for the e-trac user. On the F75 when I get a ground balance of say 91 , I know immediately what general sensitivity I'm going to be able to run.

Thanks. That is interesting. I may give that a try tomorrow..

If I am remembering right Tom D. said there seemed to be some kind of boost at sensitivity of 26 or higher.

Been noise cancelling with manual sens at 30. "Seems" to help in running high manual sens. Could be just in my mind?

need to know the actual number that the etrac decides it wants to run on. Just saying "im running in auto + or - whatever" is meaningless unless you know what the actual sensitivity is. it could be anywhere from 10 to over 30.

Personally I flip back and forth all the time, I run auto +3, and manual - basically 24 + or - depending on the site. I generally prefer to just run in manual because if I run in auto there is no sound indication to tell me if the etrac is suddenly lowering the sensitivity. I use my ears and if the chatter is bad Ill lower the sensitivity or just switch to auto unless the ground "clears up". If the ground is clear Ill crank it up as high as I can go but usually cant ever go above 26 or 27. Unless the area is very sandy or clean. Im always playing around with the sensitivity, raising it and lowering it in manual (usually) as I detect.

I believe when you go from auto to manual you also turn off the ground tracking system therefore if your ground changes the ground balancing won't and you're running without full ground cancelation. I think this is somewhat responsible for the bum wrap of lack of sensitivity to low conductors. I've found 10 gold items in the last year with the e-trac and none with the F75 hunting the same type of areas and my buddy has only found one with his MXT. Ground balance is supremely important for low conductor sensitivty and running in "manual , max you can stand" leaves alot of good stuff in the ground. My ground shows 15 point shifts in very short distances on the F75 which does not track the ground and it forces me to fast grab and re-balance frequently or the falsing becomes excessive. FBS being much more stable , if your running noisy because of high sensitivity you're also probably badly out of ground balance. It's a tight rope you want to walk carefully in bad ground.

I use minimal discrimination, multiple tones, a slower sweep and more overlap of the coil.

What is your thoughts on Auto sens +3 ?????

The Etrac has three channels that it uses to identify targets. When you set up in Auto Sensitivity, the Etrac adjusts the sensitivity for each of those three channels separately. When you set up with manual Sensitivity, all three channels are set at the same level. For example, if the Etrac determined that the high channel should be set at 20, the mid channel set to 15, and the low channel set to 10, the Auto Sensitivity number displayed will be 20, even though the average Sens is at 15. So when you manually set the Sensitivity at 20, thinking you are matching the Auto setting, you are actually setting the Sensitivity at 20 for each channel. 20, 20, 20. That higher level of "all around" sensitivity could cause your Etrac to have more falsing, produce more ground noise and be less stable than in the Auto Sens mode. Each of these can promote target masking.
When you offset the Sensitivity (-3 to +3), the Etrac will compensate each of those three channels with the amount you chose. In other words, in the example above, if you added (+3) three to the Auto Sens, it will display 23. But the channels would actually be running at 23, 18 and 13. You can't set the manual mode to match that because in manual mode, all three channels get set with the same value. In this case, if you set manually to 23, your actual sensitivity to each channel would be 23, 23, 23. Much higher than the 23, 18, 13 that you actually have in Auto Sens for this example.
