Browsing around today on Indiegogo I found something that is totally Awesome. I do alot of Fishing and have always wanted a portable fish finder and now it has come true.
"Deeper" is the first potable fish finder that alows it to be used with your smart phone. You atach it to a fishing line drop it in the water and it connects to your cell phone via bluetooth and gives you the same thing a boat fish finder offers depth water tempeture and Fish Finding Sonar.
Here is a link to the development page where you can get a chance to own one of the first 1000 made.
