pardon the long post
I am considering buying one of the new 2011 788 ci HD DI units and I just want to confirm the sonar picture in my mind for this unit.
I have been looking hard at all the HB 500/700 units trying to understand all the changes that has taken place in the last 10 years. The confusion that exists in the 2011 catalog has not helped, but i think i am starting to get a handle on things.
from a comment that a HB staff said i think it uas Greg :
the 2011 500-700 DI units without SI
They are a single beam Di sonar that is nothing more than a 2D sonar beam that is very wide left-to-right but very narrow front-to-rear and therefore cannot give you any directional information.
If I interpret this correctly the new 500/700 DI image sonar picture would be similar to the quad beam sonar picture without the 60 degree cone and the 2 DI beams shown, would actually be one distorted DI wide beam. . IE.
the wide single distorted DI beam and the 20 degree cone.
is this a correct visualization ?
Would the only beams you have to display as
a single screen would be the distorted DI beam or the 20 degree cone? Would the third option would be a split screen of the two beams.
there would not be a normal 20 degree and a normal 60 degree available for these units ( IE DI turned off )
