put two 12" sub woofers in your boat and crank them some regae music. Bass love low base. I think everyone I know who has a stereo in their boat has a story of crankiong their tunes and whacking big fish. Maybe the bass are conditioned to the everyday noises of the hundreds of boats that pass over them every week. They hear a different sound and it makes them curious??

Dan mentioned the Biosonix. I know a few of you have them.....they work!!!! I dont know if its the sounds they produce or the sounds they cover up.....but it works....

I could be the perfect example of this noise thing. I surprisingly pay little attention to it. I try to tread softly and not slam compartments, but I am on the t-moter constantly and I have my electronics on always. ANd guess what....I NEVER catch big fish.

So who knows, if its giants your after.....no noise is a must....but if you just want a 25 pound bag to win a tourney, dont sell yourself short on waisting time drifting up to a spot or killing your electronics. Time is to valuable and what you see below you on your meter can be priceless!

just another difference between trophy hunting and tournament fishing. Same species of fish, 2 totaly different schools of thought!!
