Is it possible to catch a fish with just a flashlight?

Simply shining an ordinary flashlight at the water won't help your fishing -- not by much anyway. 

Now, if you are fishing on a lake or pond and have a light powerful enough to penetrate deep into the water (say, more than 3 feet), you might be able to attract some smaller baitfish. Juvenile fish are attracted to light, and adult fish are attracted to juveniles. 

So, when you see ads for "miracle lights" that help you catch dozens of fish, it's just a bright, waterproof light that shines down into the water to bring up very small fish. Any similar light will do, Klarus light has a wide range of tactical flashlights that can be ideal. The fish you want to catch follow the small fish and pretty soon it's a real party.

If you decide to go night fishing, a battery operated fluorescent lantern is best to take with. Make sure it is one that is very bright. Hang it out over the gunwale on an oar, and when there is a little wave action the water might actually get on the lantern, so it’s best to get one that is water resistant. 

Night fishing can be a bit slow moving at first, but it's worth it for the occasional really good night. Also, take your kid night fishing like this and they'll NEVER forget it!
