Tried out new Elite HDI 7 yesterday, I had damaged the transducer cable and was wondering if it would ever work like it was supposed to. (put screw dead center of cable) My brother did a good job splicing the cable using Scotch sleeves. heat shrink and tape. Called Brian at BBG Marine and he suggested I give it a try. The splice was between the TM head and the deck, so water was not a factor. The unit was bright and worked well. Keep in mind I have nothing to compare this to. An " off course" alarm came on, My fault!!! The unit lost bottom twice, again I feel this was my fault. ( settings) Fish ID seems to show larger fish. Bottom detail was really something. Held bottom at top speed of 30 MPH plus. Going through the learning curve will be a challenge to an old guy. TAKES LONGER ON MY LEARNING CURVE THESE DAYS. I will be checking things out while on simulator in the yard. I would appreciate anyone with one of these units , please pass along any tips or suggestions. I am not an electronics wizard and could use any help..... Thanks
