I have a LX-i digital Sonar hand held depth finder made by Mar-Cum Tech. that measures the depth of the water without drilling a hole in the ice but it does not measure the ice thickness. We need something shaped like a metal detector (for easy measuring) that reads the ice thickness or an instrument that measures both water depth and ice thickness. The depth finders are based on Sonar signals reflected back from the bottom.I am looking for an instrument based on Ultrasound technology where the reading is based on density change (ice to water). A spud bar is always the safe way to go but this device, if made or could be made, would be benefical for ice fishermen. Any ideas, comments, or suggestions ? Thanks !
