I bought one in November and have really put it to the test. I absolutely LOVE it! The only time I have problems with the autorange jumping is if I am on the edge of a zoom such as 9-10ft,14-15ft, 19-20ft etc. The only other time I had it happen was in 11ft with 4 ft of thick weeds. Using the manual range always fixes the problem. Manual is quicker for hole hopping also. And the 9* Proview transducer is awesome. Can use gain to increase the angle when searching or decrease when fishing near people or in weeds.
