No camel humps???

[Aaron]

I'm hoping someone can help me on this one. I rarely ever get the camel humps when I am push the trigger forward to analyze the target. Almost always I get a straight line, sometimes it may have alittle bump in it or a line with 2 vertical lines to show some kind of size of the target. I really appreciate the help or input!
Thanks!

You have to move the coil to the side of the target and wait a second or two until you hear the the threshold. Then you have to wait the same on the other side before swinging back. It usually takes two passes. If the settings are too hot, if the detector is triggering from too much EMI or triggering off minerals in the ground you won't get the waves. This is because the detector doesn't know a sweep has been completed. Rob

rcasio44 says it

when you have the coil to one side, if you don't have the threshold, squeeze and release the trigger to see if a threshold returns. Then set it in analyze mode. And while the coil is still, then kind of hop it across the target. After the coil clears the target, stop. If necessary, hop it back the other way and stop again and see if it works. Try and determine the speed necessary for the settings you have.
I run my filter down and this requires a little slower speed to capture the analyze data and display it.
The speed has a lot to do with it. Also, the coil on one side of the target to the other, another target getting under the coil can skew the target your trying to analyze.

I had been seeing this a bit, but never made that connection. Completely logical there.

Hey thanks again Rob. I had a feeling it had something to do with that timing and speed of the coil passes.

The analysis mode is set by default to match your search mode. The fade rate on the V3 is set very slow, which also has an affect on the analysis mode, causing a long delay in being able to sweep back over the target to analyze it.

There are two methods which may help this issue:

• Increase the Fade Rate. In my opinion, it is set too slow causing info to stay on the screen longer than necessary.
• Unmatch the analyze mode so that it acts independently from the search mode. I have not tried it outdoors yet, but I was happy with the results during my bench tests.

To "unmatch" the analyze mode, go to Filter and Speed>>Analysis, then unclick the Match Search box.

Tomorrow I am going to see if I can change analysis to work in single sweep mode. I changed it from within the Configuration menu under the Live Search Screen>>Analysis>>Spectragraph>>Single Sweep. Again, it seemed to work in my indoor bench test, but tomorrow will be the real test. If you do this, make sure you leave Analysis Sizing ON otherwise it will go to the Spectragraph mode with the trigger forward.

I was doing a lot of Analysis the other day since I had problems with it to. What I found was that it is pretty easy and I could do it almost 100% of the time once I saw what was going on.

You should be able to get a good graph in two swings:

1 - Get a good pinpoint on the target.

2 - Switch to Analyze. Put the coil to the side of the target (a foot or more if possible), get a threshold, sweep across the target at normal speed and stop on the other side.

3 - Wait until the screen refreshes and the info on top of the screen comes back. You will probably see a small image of the graph which just means that the graph is set up, but no data (I think).

4 - Sweep across the target at normal speed in the opposite direction.

5 - You should have your graph.

Turns out that I was trying to rush it. That pause after the first scan is the key.

Yup! Thats right Beep, Rob had said it earlier and it works!
Thanks guys!

On mine it seems that the quality of the (hump) depends a lot on the depth of target. I'm talking a few inches only.
