Soooo the airmar failure thread has me a lil spooked.... Ill be setting up a boat soon with a B75H installed and planned to go with the 2 n 1 for side and down scan. Now Im thinking maybe I should go with the 3 n 1 so if the airmar craps the bed I still have 2d sonar. So now I just wonder is there any disadvantage to doing so (ie will having the extra element result in any difference in down and side scan)?
Also is switching between the 2 as simple as going into the source menu and selecting the ducer I want to get input from?
Thanks guys
