Thank you for allowing me to assist you, my name is ***** ***** I will be happy to assist you with your concern today.
Usually this is a bad transducer, not the main unit, however the main display guages do go bad from time to time as well.... honestly, your better off just replacing the main unit and the ducer if needed, this way it is also an upgrade and a new unit. Make sure to check the wiring/connections that they are tight, clean and not damaged.
Any good quality depth finder gauge that fits the same hole will do, they are pretty standard units. There are tons of good manufactures that make these and you do not have to stick with a lowrance if you would like to change. A new lowrance model would be such as this:
Thank you!
