[cool][#0000ff]Don't confuse an ice fishing sonar with a magnetometer. The latter is capable of shooting through the ground...at speed...and registering metallic anomalies "on the fly".[/#0000ff]
[#0000ff][/#0000ff]
[#0000ff]To get your sonar to shoot through the ice, you have to stop, put some water on the ice, set the transducer in one spot and let it shoot and respond. No high speed cruising.[/#0000ff]
[#0000ff][/#0000ff]
[#0000ff]But, the other answer to your question is YES, most sonars capable of shooting through ice will also register fish...depending on quality and sensitivity. There are also the variables in depth of ice, the consistency of the ice, etc. Ice with a lot of air bubbles and fractures may not produce a good readout. Ditto for trying to shoot through a top layer of slush. If you are travelling across snow covered ice you need to stop, clear a spot over clean ice, dribble on some water and then shoot.[/#0000ff]
