You may be on to something. I know I calibrated it when I originally installed it but now it's saying that it's not calibrated. I am going to try to go fishing tomorrow and will mess with it some more. I am learning a little more about it from y'all's suggestions. WTM mentioned the AHRS. I didn't know anything about it so started doing a little reading. If I turn the AHRS off then it gives the ability to level the bottom. I'm going to mess with it. I have another transducer I can swap it with if need be but hopefully I can get this one figured out. I didn't have any problems when I first installed it.
