I recently purchased a Humminbird 959ci hd di and am having trouble getting a usable sonar signal. Neither the down imaging or the 2d imaging offer a usable view. I have a fiberglass boat and have the transducer mounted inside the bilge area. My prior unit (Lowrance) had the transducer mounted in the same area as the Humminbird transducer and it produced very good results. I would appreciate your input as to where you have your transducer mounted and what type of performance you are getting. I have spoken with the techs at both Humminbird and Ranger and both recommend placing the transducer exactly where it is now. My installer has repositioned the transducer but the performance remains poor.

Any input would be greatly appreciated.
