V3i and cannon balls

[Doran]

Hey everybody. New to this forum. My brother found a cannon ball but whenever I swing my detector over it, it nulls out. Is there a certain setting so that my machine can detect these?

Sure you have to accept more negative VDI (iron). I'm sure you have iron discriminated.

Did you read the sticky at the top of the posts about what to include in a post?

 

[Larry (IL)]

It sounds like you have the discrimination set too high for cannonballs. Most of them are made of iron and if you are a coin hunter, iron is discriminated out. Try the relic or Hi Pro program. All Metal mode or pinpoint should be able to detect it.

I tried accepting negative vdi numbers and it still nulls out. I always search in relic mode. Not understanding this! Have y'all found any cannonballs or cannonball fragments?

Keep messing with your discrimination, if the cannonball is metal the V will pick it up. Pinpoint the cannonball and see what the VDI is and make sure your search mode accepts those VDI's.

It pinpoints it but pinpointing doesn't give a vdi number. Putting it in all metal mode I think have a -95 but no audible tone.

Go to Discrimination and uncheck Visual Reject, that will allow rejected VDI #'s to show up on the screen. Be sure to start with the coil a foot or two away from the cannonball and scan, you should be able to have a visual and audio response. If the cannonball still reads a -95 but no audio, the audio tone for -95 might be turned off.

It might be overloading and probably you have no tone assighned for overload. How big is your cannon ball?

 

[Doran]

I'm thinkin around 8 lbs

Appreciate your help Larry. It now shows negative vdi's but still no audio. How do I get the audio to work for those vdi's? My machine just grunts when it's like 4 inches from it. If I go higher it won't do anything.

 

[Larry (IL)]

We don't know how you have the tones set on the negative numbers. Remember, you can assign any tone that you want for any VDI or group of VDI's. You can make cannonballs scream like a quarter if you want to.

 

[Doran]

How do you assign those tones?

Look in "Rob's Reference Links" at the top of the page and then click on "Carl's Shortcuts". It's easy and Carl provides step by step directions.
