report on lcd vs flasher fishfinders

[Fowl-Hook]

Grayline is a Patented Lowrance feature that helps you distinguish between hard and soft bottoms, where the thicker the Gray band the harder the bottom. It can help separated fish that are hugging a hard bottom that is flat. There may be 3D units that indicate a sloping bottom but I have not seen one as of yet. Gray scale is a terminology that other manufactures use for the same feature.
Ice fishing is indeed the ideal place to learn and compare Graphs, a unique opportunity to have the transducer perfectly motionless.
