Fish finders - help needed

[Bigcat]

Some of the newer, middle and upper priced units have a real time flasher feature. Its called different things on different brands. Basically the flasher is located on the far right of the finder screen and is about 1/2 inch wide. It give the raw feed back of the sonar without any interpretation of the data. The returns from the water are instantaneous so it is "real time". You can watch your jig go up and down the water column without any processing delay. You get the same thing from a "flasher" finder only it displays on LED lights rather than an LCD screen. Go to the hummingbird or Garmin websites and read about the real time feature. Its really cool for ice fishing! Hope that helps
