COG mode on fresh water beaches ?

[dfmike]

Just wondering if I'd gain anything by using COG mode on fresh water beaches as opposed to salt water beaches ? It rains here quite often so the beaches I hunt are rarely dry. I thought COG mode might help me in the wet highly compacted sand.

Can I expect to lose much depth compared to DI2 for example ?

Thanks.

The advantage to using the COG mode is that it allows the detector to ground balance down to the salt. There will be no advantage to using COG on fresh water beaches rather wet or dry.

On plowed field after switch to COG we get perfect silent. Almost no ground respond

Thanks Tom Slick. I guess there COG mode will be of no use to me then.

No benefit whatsoever with fresh water beaches. I had to use it today for a brief period because My machine went crazy over a small piece of ground and would not ground balance. After that all was good. I think it was discarded coal in the area.

Thanks Tom!

You will loose up to 45% depth in cog mode when compared to deep mode. To work on salty conducting sands the sensitivity is reduced INSIDE the machine. by the software.

Yes but sometimes you need to do this to get the machine to behave... Like for me today...

One thing I didn't mention in my earlier post is that COG mode can also be used sometimes in areas with exceptionally high EMI to help calm the detector down when the frequency shift doesn't help.

This is what I had to do yesterday!

Interesting idea.
