Outdoorsman I have never fished Ebenezer creek, always wanted to but never have so I can't help you there. as far as your sonar unit I will be happy to help you set it up on your boat. If you send me a pm with your phone number I will give you my address and will be happy for you to come over and we will set it up. you need one at Lake Mayer to find the crappie but the crappie are in the lake..Hope this helps. Jimmy
