Does anybody here use any maps when fishing? Looks like there is a ton out there And wanted to know what has helped people the most

Also I am a bank guy so really trying to figure out what I'm casting into looks like.

This isn't specifically an iPhone App, and isn't my original idea either.  I have been using Google Earth to look at lakes and ponds that I fish.  There is a feature that allows you to review historical images of an area.  Using this I was able to search backwards in time to find a point where the water in the lake/pond was lower than average.  Doing this allowed me to see some of the structure that is revealed by the lower water line.

 

For instance using this trick I was able to discover a shallow ledge/point that sticks about 200' out into the lake that I am going to try fishing next time I hit that lake.  I was also able to discover a couple decent sized humps in another lake.

 

Obviously you mileage may vary, but this is what I have done to get a feel for what might be under the water where I fish.  It isn't great but since these lakes don't have maps available it is the next best thing to a fish finder.

Navionics has a product called Mobile App for smartphones and tablets.

The coverage probably will not be available for small ponds though.

 

You can view the maps on their web site to see if your waters of interest are included.

It is their Web App.

Thanks for the tip on Navionics.  It doesn't look like it covers some of the lakes and ponds I fish, but it covers the big ones around me.  This is huge for me as I have been a bit intimidated to go on "big" lakes as I really had no idea where to fish.  For example, one of the maps I looked at showed basic things like depth which pointed out ledges, humps, etc.  It also had markers for submerged timber, some down trees, etc.  This gives me some great options of where to fish.  Now I can't wait to hit these lakes up and see what I can catch.

navionics online is awesome, really helps pass some miserably boring time at work for me some days

I use the Navionics app.

Thanks for the Navionics tip, seems like a pretty good tool.

How about this baby?
