These flashers are just a bunch of entrepreneurs trying to cash in. They're from the Great Lakes and the States.
No commercial boats fish with them..and if they did, it would not take long for them to really explode.
If you believe that you're going to catch a fish because of fishing with one of those flashers whereas a "conventional" dodger or flasher wouldn't catch the same fish, you've been "hook, line and sinkered"
If so..why not use a dummy flasher? These new flashers are DUMB and something so dude thought up in his basement in some drunken state after making a few empties trying to look for excuses for why he wasn't catching fish. LOL!
Everyone wants to build a better mouse trap....yet most people fail. Quick..somebody contact the scientists..get them on this quick! lol.
