Bird don"t get hung up on brand. Think of what you want out of the unit then compare the ones you choose. Low HB and Garmin all make good units just some have features the others don't and remember all brands have some flaws. By doing the research on the ones you choose you can then see what units others have had problems with like dinobot talking about the 176i. Right now new units are out and lot of folks are getting rid of older stuff (to them) like dino said and great deals can be found. You could probably find a usedLowrance Elite-4 Base Chartplotter/Fishfinder Combo for a good price. Clear image and I like that the map that comes with Low shows the channel.
