Fish finders & Red fishing line

[Trent Hale]

I have watched a fishing show and the guy was saying that fish are turned away by fish finders when the sonar waves hit the fish. Has any one heard of this? And he also talked about red fishing line that fish can see it and it dosen't dissapear under water that its a sales gimmick. The guy I was watching is an under water diver who has studied the movement of bass and there habitat.

Now that you mention it, I've had better luck when the fish finder was off. I usually use it when I'm trolling to check water depth -- not to locate fish.

As far as the color red goes, I've had good luck with lures that had some red in them, but were not ALL red.

I don't know if it makes a difference but I have turned off my fish finders in shallow areas that receive a lot of fishing pressure. They do make noise and if a fish has had a negative feeding experience (like getting caught on a lure) ,or even worse multiple negative experiences, it may learn to associate that noise with danger. I also don't think the meter is that helpful in shallow water so why bother leaving it on. In deep water I am usually trying to fish a certain depth and or structure so I don't really have a choice but to use the meter.
I totally agree with the red fishing line thing. The theory was that the color red is the the first color in the color spectrum filtered out by the water. This is absolutely true. The problem is it doesn't become invisible it looks grey. So if you want a line that looks grey use it. If you want a line that is virtually invisible use fluorocarbin.
