Advice On Portable Fish Finder/depth Finder

[livetoskate]

I am looking to get a fish finder but it needs to be portable since I don't have a boat. Usually I will be renting a boat when I use it.

Any advice would be great.

Thanks

Hummingbird makes a great portable depth finder, the Fishign Buddy. Used to be made by Bottom Line. They work great. Depth finder, temp guage, etc. Runs on batteries. Not too expensive.
