Thats a pretty nice unit. It has a dual beam transducer. It will be looking straight down with 20 deg cone and 20 deg. out to each side. there are other post on here that explain this alot better. Jerry Blake has a good post that I believe is a sticky that goes into a better explanation on graphs and fishfinders. with the single 20 deg cone you would see a 2 ft circle on the bottom of the lake in ten foot of water. so with the dual beam give you a 60 deg. look right under the transducer the thing i read on it said it also has sonar. but not to familar with the sonar looking units. there are more knowledgable people on here that will chime in. the post of Jerry's is on the archive things we don't want to lose on the main page it called (getting the most from your graph).
