Plastic swimmers are excellent fish producers for me. Since Numbskull (

) can't fish them, I will tell you.
Night is usually the best time to fish them but overcast days or dusk/dawn they are also productive. Of course if you fish them enough during the day you are bound to hit something.
Not too much wind is ideal unless it is at your back, then you can sail them out there if need be. If you load them you can get away with a little more wind. Always fish them slower than you think you need to.
I live on the L.I. Sound and these swimmers occupy alot of space in my bag. The Mag Darter has become a go to if the bass are slurping baitfish off the surface, day or night.
During the spring these are a must in your bag for back bay fishing. Tie on a teaser and you have a deadly combination.
