? deep target

[bula]

When you talk about a deep target what does your bar show. With my mxt even at 9 or 10" most of the time I still get a full bar and the vdi reads correct when in coin mode. Is there something I am missing, if I do not get a 3/4 bar there is not a good target in the hole most of the time. Lately I have had the discrimination turned down to 5 & still get good hits at 7 to 9 inches. I know that the closer to the top the louder the sound & the deeper is gets quite but I still get good readings.

If you're hitting a really deep target you probably won't get much, if any reading at all. Certainly not an accurate one. If you're getting a full bar and accurate ID, your target probably isn't all that deep. I don't trust the depth on the display all that much, personally and seldom pay much attention to it with solid hits as I'm going to dig regardless of depth.

That is some good info. I am new to this hobby also and every little bit helps. Thanks

Hi bula,

When you talk about a deep target what does your bar show.
That depends on the size of the target and if there is junk near the target. A dime will usually read 78 - 82 for me. If you put a piece of junk or even another coin close to the dime the numbers will change. If the numbers change the detector won't show a full bar because it is not sure what the target us. Usually the ID accuracy starts to drop off with depth.

With my mxt even at 9 or 10" most of the time I still get a full bar and the vdi reads correct when in coin mode.
What kind of targets were you finding at 9" deep and what coil were you using? Where is your gain set? Are you saying you get a coin at 9" or 10" that ID's correct and gives a full bar? The only coil that reads very accurate for depth is the stock 9.5. With some of the other coils that 9" coin reading is a really a 7" deep coin. Are your depths measured or a detector reading?


Is there something I am missing, if I do not get a 3/4 bar there is not a good target in the hole most of the time. Lately I have had the discrimination turned down to 5 & still get good hits at 7 to 9 inches.
At disc.5 I'm already losing the nickels and a lot of rings. What kind of hits are you getting, I mean what are your VDI numbers?

I know that the closer to the top the louder the sound & the deeper is gets quite but I still get good readings.
If I run my detector hot in the plus range, I lose the modulation. The audio is amplified and the deep and shallow targets start to sound the same.

Anyway you seem to be doing better where you hunt then were I am at. Keep up the good work. Rob

It all depends on the coin and depth, I find that if in good soil and not a lot of junk I have had a penny hit a full bar at 9" to 10" when I found it it was laying flat and was over 12" deep. If it had been on it's side I am sure it would not have given a full bar. I also find that if there is a deep target that is not locking in I simply swipe the area with my foot taking off the top soil, this always seems to help. I use the 6x10 eclipse & the 4x6 dd depending where I am digging I have found coins at 12" or more that gave a 3/4 bar using the 6x10. I run the discrimination at 3 or 4 most of the time I like to place a nickel down & tune in on that so that I still pick it up. With the 6x10 a nickel gives a solid 20 every time, the 4x6 gives a 18. If I can get a solid hit with a setting of 4 or 5 that is where I leave it.

With both of the coils I use I start of setting the gain at 6 or 7 and the discrimination at 3 to 4 I get a lot of coins at 7 & 8 inches, If I get a weak signal with these settings I turn up the gain & I find that it will help find those deeper coins.
