I put my money into a Raytheon, now Raymarine. They designed and built the sonar systems for the navy, thought that was a good bet,Have a L365 cost about 300.Dual freqs for dept and clarity, temp,distance and speed. Has worked great for me and will read to a depth of 2000 ft, sometimes it gets deeper than that out there, but i have had great luck with it and have put it to some long days of fishing,Hope some of these comments help, Fishy p.s. now they cost about 200
