Any geniuses out there who want to make money? Here's how...Make a map chip like Navionics. Then make it so that when you load it in your fish finder you can enter the lake level for any given lake. Then make the map adjust to that level. For good measure make it so that the user can program any given depth to show in a certain color. For example, if Lake McClure is down 120', let the user program that in and show anything less than 10' deep in red (hazard) and anything less than 60' deep in yellow (possible places to fish). For the Delta, make the map chip calculate and show depths dynamically based on the tide forecast.Someone needs to invent this.
