...unless you have somewhere else to go, you wont find anything if you stop. When you have the chance to detect... detect!
As for ideas, well... off the top of my head - -
- The gravel could have been dredged and piled on the beach - some places do that, especially on big bodies of water.
It may have also been brought in, which is what I suspect. Heres why
Pea gravel is worn gravel, eroded by the effects of moving water. That aint gonna happen in your average lake, where native rock on the bottom tends to remain in its raw state.
So when you find pea gravel beaches at a lake, you can expect that the gravel is trucked in to build up the beach. The good stuff could be buried way down below the layer of gravel you see. That particular beach may actually be the LAST place you should be detecting.
- Another consideration is that water rises and falls, particularly in a reservoir. The beach YOU want may be under water or higher up the bank. Or down the shoreline somewhere.
So look outside the confines of the beach you currently find yourself on .
- Consider getting out into the water. When someone loses something on gravel, it is easier to spot and recover than it is in sand - which immediately covers it. But in the water, its a different story. I found a nice ring last year in ankle deep water. There are many who say most jewelery IS found between ankle and waist deep water. So triple wrap the control housing of your BH against accidental immersion and get out in the water.
- If there are any park personnel, workers or residents around, ask them where you should be detecting. If anybody knows, its them - and they may appreciate you appreciating them for their knowledge.
