With eye sight not what it once was I have been looking to go with a bigger screen from my old 5 inch Humminbird 788CI. Really wanted a Lowrance HDS 9 Live with Nav+ but at $2,950 + tax that simply wasn't happening. I found a great buy at $750 on a Lowrance Hook Reveal 9 HDI with Nav+ and another $100 off that with the online rebate so I pulled the trigger. Always had Humminbirds but thought I would try a Lowrance so hope I'm not disappointed. I only need the traditional chirp sonar I'm comfortable with so really don't need down or side imaging. I'm confident my new knee is now up to the task of crawling around inside the boat doing the install... I think.
