TRINITY'S 3rd annual 2012/2013 icing challenge

[DetectorGuy]

I have a portable scuba directional finder. I use it on every dive and I love it. It is kinda wierd how it works as it doesn't use batteries. It needs a little thinking on the divers part to make it work correctly, but it is very durable. The one I have is not exactly like the one you posted a link to, but the one I have is quite a bit cheaper. I think I only paid $53 for it a few years ago. Of course the one I am talking about is a Suunto Compass... Sorry to mislead you, but it was fun for me ;D ;D ;D
