yeah try turning your sensitivity off of automatic and adjust it yourself until you begin to see marks...you can also try resetting your unit completely (won't reset wpts or trails) and then adjusting the settings from scratch

thanks for the information...How Can I reset the unit? How low can I go with the sensitivity? I havent played with it too much.

If you are not marking fish you need to turn the sensitivity up, not down. Should be a manual and auto setting change it to manual.
