![]() ![]() I haven't checked the actual cone angles, but 11 degrees sounds heaps better than 20 to me. #Are you aware of these issues highlighted above? #What differences can you see on your screen at these depths? They get Airmar to build them a 20 degree, 200 kHz transducer." #Long story short, if you are fishing the bays and reefs I'd definitely stay away from the Furuno until # ![]() Now, Furuno proponents will tell you to simply swith over to 50kHz in shallower water and get the #ģ7 degree cone angle but that too is flawed as at 50kHz you get little detail. Here's the skinny: Furuno's 200kHz has a 11 or so degree cone angle, while Garmin offers it with about 20 degrees. #Having said that let me say I own a 582 now and have owned probably a dozen Furuno machines in my life. If you are fishing offshore it is not an issue but if you are fishing in waters say 40' (about 12.2m) or less, think twice about the Furuno. Here is an extract form another Forum I found regarding COne angles for these Furunos - looks concerning from 12m down. Of course this assumes my transducer is mounted level from side to side and ignoring the slight forward angle to help dissipate air bubbles. #I am curious how far off of a small structure I could be while still marking it on the display. #Ultimately what I am trying to determine is at 30 to 50m of water depth how wide of a bottom scan is the machine showing. I am trying to find out what the official angle the transducer sends and receives its signal at both 50K & 200K.
