Can I have the GPS location because I am a metal detectorist.

Just kidding, I don't have the scuba gear and seawater detector. Those kind of detectors are about 2 g's
There are guys with that kind of metal detector that will find it for you here

And that goes for anyone else here that loses their N9 just ask me for help, I am part of a large group of metal detectorists online all across the world and we are very helpful to others (but it is good manners for you to give a tip). I can try to locate you a person in your area if that ring finder place does not work out for you.
