Additional Information
The above information is for 10 or more events at the same dive site, we do that as a dive shop continuously throughout the summer, on the cliffs are plenty of fisherman sitting so the most common objects are fishing related. We collect mostly lead sinkers as lead is particularly harmful and also can be upcycled to scuba weights.
4 inch artillery shell from WW2
lead sinkers
fishing line
plastic debre
Comments and Feedback
I understand that it is important to log all the information but the communication from PADI was, just take a lot of pictures and upload them in the end of the year, it should be a bit more user friendly.
We also cleaned up at Maeda point, a very popular site close by, plenty of debris mostly snorkeling related old fin straps etc as it is a tourist location
