Fish Finder/GPS

I am new to Kayak fishing and am interested in Buying a Fish Finder/GPS unit for my 2009 O.K. Prowler Trident 15'. I will be fishing every where I can get my Yak into, ocean, bay, delta, rivers, and lakes. I'm looking for something user friendly and not super expensive.

 Any ideas would be greatly appreciated.

 Thanks B.A.

  P.S I had a great time meeting and talking to some of the Norcal Kayak Anglers crew at the Sportsmen Expo. You guys were a wealth of information, good job Representing.

First of all wellcome to the Madness
Sorry I do not have any info to help but if you re-post your questons in the "gearing up" column I am sure you will be happy with all of the answers that will come your way and maybe learn a few things you did not know you needed
Enjoy your new kayak and be safe
