Hello All,
I have a Pirahnamax 4 fish finder that I'd like to get the most out of until I upgrade next season.
I primarily fish two lakes - one is relatively deep and clear, while the other is shallow and not as clear.
The deep lake is as deep as 180 ft. The visibility is approximately 30 feet or so. I usually fish from 70 - 90 feet.
The shallow lake is about 60 feet at deepest, but I fish in 20-30 feet of water. Visibility is considerably less.
So far, I've been keeping the unit on the 200 khz mode for both lakes, with the sensitivity turned up about 6/10 for the clear, deep water, and about 7 or 8/10 for the shallow, murkier water.
Would you do it any differently? A I using this thing correctly?
Is there an instance where I should be using the 455 khz setting? There's not much structure in either lake. Both are man-made reservoirs that were pretty thoroughly cleared before filling 50+ years ago.
Last, I get a lot of interference while I'm running from one part of the lake to the other. I've been sure to follow the advice of making sure the transducer is away from the prop, at the correct height, and away from the strakes and rivet lines. I'm only running a 9.9 on my boat, and not moving very quickly at all. But I still get a ton of interference, and would like to see if there's a way to optimize the sonar while traveling around the lake.
Thanks for any advice you can give.
