Hi All. My 13-year-old Lowrance elite 5 finally kicked the bucket. Not sure if it is the transducer or the unit itself, but it only picks up depths 5% of the time. I'm ready for a new unit. I currently use my boat for prawning 90% of the time and fishing 10%. Now that I live on Gambier Island full-time, I'd like to make it more like 50-50. Is there a unit for under $1000 that is good enough for what I am looking to do or will I regret not spending a few extra $$$ for something better? I'm overwhelmed by the choices out there. Thanks in advance.
