100 GM Cuban link Gold Chain found on South Beach Miami Florida Returned to owner.

As I was metal detecting in the water on South Beach Miami Beach A couple of guys approached me and asked me to search for a gold chain for them. I spent two or so hours looking for it but after analyzing the situation and having only found beer cans and pennies. I thought we needed to go further out. The problem was it was getting to be the highest tide. So I took a break and waited until the tide went out further they agreed and after signing the contract. I continued to search way out for another 1 hour or so with little results. After discussing the possibility of a need to come back another day and or switching to another metal detector with better sensitivity. I got a target.!!! And brought up the gold chain in the picture. The owner was sooooo happy to get his chain back.
