No I did not buy an ultera. The last couple of trips my lowrance HDS 8 that is mounted on the console has been acting up so I decided to replace it. Just so happened that Cabelas had refurbished HDA 8's on sale for $649.00 so I ordered one. It came in today and I am going to install it tomorrow. I want to change out the transducer also as it is the original one that came on the boat. This may be my problem but not sure. Want know until I do some checking. I got a 7 on the tracker with a new transducer and if it works okay on it then I will install it on the tracker and move the 7 to the front.
