Hello guys ; I'm a newbie here and I bought a new ranger a year or so back with hds carbon units ... Now I don't have the 3D transducer because I just can't see where the image difference is worth a grand ...but here's my question ... My previous units were hook2 7's and I can't see where the carbon unit is even as good ... I liked everything about my hook series better and I've about made up my mind to switch them out .. But before I do I wanna know if anyone else has felt this way or If I'm doing wrong because the carbon units are about 3 times the price I would think that they would be much better but really the only thing I see that's actually better is that imaging is a little closer to real time...
