I am looking to buy a fish finder for my 10ft jon boat. I dont wanna spend gobs of cash. Whats a good easy to learn on model to buy at a reasonable price. Never used one before so I need one thats self explanatory or something easy to work with. Thanks

Eagle Fishmark 320 or 480

I'm also looking for a sonar and based on the conservation down the page, I am about to buy the Fishin Buddy 4200. The Fishin Buddy 4200 is portable which fits my needs for various craft that I plan to use at one time or another.

I was thinking of spending about $200. I won't be fishing over 100', mostly 20' or less.

This is a first time buy for me also.

for the post and all of your comments.
