Im sure this question will get some good laughs! So I just got my fish finder the other day and also got some marker buoys to mark spots as I troll along. My question is how to use them. I see that it has 75' of rope and a small weight, do I just throw the buoy in or do I have to let that weight all the way to the bottom acting as an anchor? Im just wondering, cause in my mind the weight falling to the bottom might scare away possible fish. But just wondering on proper use of the buoy.

Thanks
