When the going gets tough..use the depth finder
 

There's a glare on the depth finder...but the BIG FISH ALARM went off..this is the spot where I was broke off..I think I found a honey hole {-;..when I can't get a reaction shoreline hit..I use my portable fish finder..119.00 Walmart ..I keep an extra set of batteries...These finders are very nice..Have had mine for a long time..I accidently left it in the boat..The tropical storm rained all over it..I thought OH NO!!..It turned right on and worked perfect..His Mercy Endureth Forever..It's a nasty glare but the fish were in 18 foot of water.
I fish A LOT!! I change batteries about every 10 trips..Takes 6 AA batteries.

Those depth finders surely help to locate the fish, but, they do not make em bite.. They are great in my boat as well to help find those darn ledges and rock piles we have up here..
