Cell phone fish finder

[BHuij]

Seems like a good way to go for someone like me who can't realistically be spending money on a fish finder anytime soon (what with tuition, upcoming wedding, etc. etc.). Shame that my passion for fishing is picking up right when I'm really exiting that time period where spending lots of money on toys for myself is doable Ah, well. I have enough toys.

Are there any decent systems like this on the market already that work with an iPhone 5c?
