When a psd searches a area and is done, he has proved one of two things. name them. this should be a snap for you Gary.

Either your target is there or it's not there.
 
...Or that a different technique needs to be utilized (better metal detector, more experienced diver, more overlap, etc).

Public Safety Divers are HUMAN ... they can make mistakes and no one (myself included) is perfect. If you asked me to find a pin head in zero vis, I might not be sucesssful on my first dive but if the benefit is great and the risks are minimal, I can assure you (or anyone else) it WILL be found! It may take more than one dive, more than one type of technology (a stonger magnet ... remember those days!) or a younger diver with better eyes.
