Helicopter at Patricia cove this past Sunday

[BrunoSR]

Does anyone know what this helicopter was doing at Patricia Cove on Sunday (7/29/18). It circled the cove at about 100’ off the water and then went around again at above 25 feet or less. Couldn’t tell if he was lost, looking for someone or a sight seeing mission. Seemed so odd that he was so low to begin with and then going in even lower. I am no expert but looking it up on google it look like a Robinson Helicopter.
