I have questions. What are you looking for? And if you find it how are you going to recover it?

I'm with MDM. Need a little more info so we can possibly help you.

The only thing I am detecting the Bed Rock for is small nuggets and I am usually swinging a detector that has a gold mode
as @MasonDixonMding said what are you searching for
as @MasonDixonMding said what are you searching for
I'm looking for small gold nuggets. Or any gold at all. If i'm not mistaked a crevicethat is perpendicular to the way the river flows is better than one that is parallel to the flow because in a flash flood the sand and gravel tend to wash out any thing in there.
Thanks for clarifying what you are looking for.
For small gold nugget crevice hunting I would try Park 2 Multi or Field 2 Multi using DP tones. Lower the iron tone break to -16, -17, -18 or -19 if there is a ton of black sand and hot rocks. Lower the FE iron bias setting to minimum, use recovery speed on 3, 4 or 5 and press the horseshoe button to accept all targets. Hopefully you have the 6" round coil. Be careful not to detect with the coil touching the lower carbon fiber shaft since the carbon fiber shaft is detectable. Set sensitivity around 20 to start, noise cancel and you may need to ground balance often. Small nuggets trapped in a crevice with black sand may give weak audio responses with target IDs in the low teens, single digits or even negative numbers. Go slow.
Good luck.

Glad you answered this Jeff having never held a Equinox 700 in my hand or even looking at the 700 online I did not want to steer the OP wrong in setting up his 700 to detect for anything on bedrock, was hoping you would chime in on this one
Been there and done that with the 800, 900, Manticore and Legend.
I just gave him a solid foundation for a starting point.
Every site is different.
First, thankyou for such a detailed responce. My eqinox 700 came with a 15" and a 11". I whish I had a smaller one like the 6" I will try park 2 or field 2. I don't know what DP tones are. But I have to learn this stuff. Iknow what the iron tone is, it's deep and low. have to check out my manual. Knowing the carbon fiber is detectable now is great info! Thanks alot J
DP tones are a two tone ferrous/non ferrous VCO audio option on the Equinox 700 and 900 which acts and sounds like the VCO audio on the 900’s gold prospecting mode. It will sound off on the smallest targets better than the “normal” Equinox audio. It is an option under the audio settings for number of tones. VCO is what most gold prospecting specific VLF detectors use since it gives a ton of information about the target and is more reactive to target size.
