Bait is always a good choice any time. But, it is everything if it is not in the right place. Make sure you are fishing the break in the bar and for an incoming tide fish the inside of the bar and for the outgoing tide try to fish the outside of the bar.
All to often I see guys set up right in front of a huge sand bar and wonder why they are not catching. If they would only realize that their bait is in maybe 10 to 12 inches of water and not to conducive to catching anything but a sunburn.
Learn to read the water and you will start to catch more often.
Happy Catching
