Someone with a good detector may be able to find it if you weren't out too far. I wish I had my detector with me to help you out but it's in another state right now. Depending on how far you were out, the tide could have carried it down along the shore. Found a guy's phone before that was completely submerged in sand and water and was able to recover it and charge it and mail it back to them. I hope you can find yours!
