I found a particular unique computer/data logger while diving last Jan in Mexico. At the time I did not know what it was, but have since found out. I cannot download or figure out the person who owns it.
But if you lost something and know what it is and what cave you lost it mail me and if you have both correct then I know its yours and will try to get it back to you.

Would be interesting to know who's it is and when it was lost as it was buried when I found it. Could have an interesting long dive recorded LOL.
Thanks
Bob
