I keep getting signals in tide pools on Vancouver Island!

[SlipperyT]

I recently bought a property in Nanoose Bay on Vancouver Island. We got very lucky and managed to fix up an older home right on the water. So a year later i finally have time to adventure!

I fired up the metal detector and headed to the beach at low tide. There's bedrock everywhere and the shallow tide pools sit right on top of the bedrock. Somehow every single pool sets off the detector for non ferrous material.

The real challenge im noticing is clearing the pool is quite difficult. What i need is a pump or something to drain them. Before i go to the trouble i was wondering if anyone else has experienced a similar situation. Am i wasting my time? Are these super false readings? Any help or advice would be much appreciated!

tide pools are in the area of the arrow. They continue around the corner.

The small pool is where the water is evaporateing, increasing the salt concentration. This increases the conductivity of solution high enought for the detector to "see it" compared to the naighboring rocks and false as a metal. You can try a few things; go detecting right after the tight, when the pools are still fresh and /or try to set the ground balance higher and the sensitivity lower. Eventually, you might need a better detector, a high end multi frequency VLF or even better a PI, wich seems to be less prone for those problems.

Beautifoul landscape, congratulations on land purchase.

What detector are you using? If there is no sand on top the bedrock, nothing will be deep, so, you should be able to turn the sensitivity way down to get it stable. Use a good pin pointer to locate the target and use a screwdriver or similar to carefully pry the target out of the rocks.
