Question: how clear are the fish
Document: The pictures are crystal clear, the structure is amazingly visible, fish are easier to find. Very good product that I would advise anyone looking to upgrade to buy.
It was cool to see the difference. I think this will be useful when trying to precisely anchor in these situations. I marked many fish throughout the day, however, I can not be sure if they were real, junk in the water, or artifacts. I need to run some tests in some really clear water some day.The DI capability was impressive. I fished over a lot of rocks and boulders and they showed up very clearly.
The best way to start a conversation is to crisp clear view of bottom, small transducer, easy of use, accurate depth, nothing to ask to other more expensive equipment. Very well suited for weekend fisherman on fresh or saltwater.Nice screen size...
Overall I really like the unit, but not Humminbird.I sound harsh, but I would just get a 2D, or move up to a larger screen unit.I was very let down by the down imaging hype and pretty pictures that humminbird shows on their ads.The unit is great, and I love it, but don't think for a second that you'll see what the ads show. You might if you are running on an indoor swimming pool with NO wind and crystal clear water.
I received this in excellent condition. The assembly instructions are a large fold out with scenarios for two different transducers. They are fairly clear, but the illustrations could be better and should be larger. I got the transducer ready to install, spun on the 1/4-20 pivot bolt locknut finger tight, adjusted everything, went to tighten the lock nut, and after about 1/2 turn it galled and seized. The bolt had barely contacted the nylon on the locknut.
Nice top of the class fish finder. It adds vaule to my boat and it is a great tool  for me.
It's my first fish finder and so far so good. Reads the bottom well and it has many user settings to customize your fishing needs.
Sounds crazy but this thing truly has changed the way I fish and made me a better fisherman! I just cant imagine what they can come up with next.
I probably should have considered one with a larger screen but this product matched with Lakemaster chip really works great. Very accurate as to position which really helps with the varying depths where I fish.
I wasn't certain how useful down-imaging would turn out to be for my style of fishing. After several months of use I've found down-imaging indispensable. It helps me precisely locate structure & fish that I previously would have missed.
Answer: As far as the down imaging portion, you will only see the air bladders , blotches on screen,of the fish but see structure very detailed. The graph will pick up the fish well. Pretty awesome product. I do a lot of crappie fishing. So I can identify structure and if there's fish on it. Priced reasonable also.
