This sonar works good. I was surprised to see how shallow one pond was that I fish at. And I was surprised to see how another smaller pond was much deeper. The graph is easy to read and see weeds and bottom contours. I have not had the chance to view an underwater structure, like an old dock or timber, etc. Fish are viewed in a different color so easy to see on the graph within the weeds. I found there is a lot to reading a sonar, like being able to identify the bottom type, thermoclines, fish, types of weeds, etc. The graph provides enough data to gain a lot of knowledge about the lake bottom and fish location.
I did have one major problem, I casted the sonar using a nylon line on a windy day. Sometime after getting the sonar out the line to the attachment point on the sonar unscrewed off. I pulled in the line only to find the steel attachment point on the end of the line. The sonar was still out in the water. It was too far to reach with a stick and from the sonar graph the water depth was around 5.5 ft so too far to think about walking out to it. Luckily the pond was small and it was very windy. I waiting about a half hour for the sonar to reach the other side of the pond and was able to retrieve it. I did check the attachment point after I attached the line to it. I think it unscrewed a little while dealing with it in the wind and unscrewed the rest of the way in the water due to the wind. Really glad I learned this lesson while in a small pond. I will use locktite on the screw from now on. Really need a better way on these connection points, a simple screw does not work well.
While I was waiting for the sonar to reach the opposite side of the pond I did get a good lake map of the bottom. During this whole time, including when I walked around the pond to the opposite side I did not loose wifi connection. I thought I would because going around the pond took the sonar to its limit. I did have a very hard time spotting the sonar in the water from the other side. The sonar is black and the water is dark as well. At first I thought it washed ashore and was in the weeds somewhere but I looked at the sonar map and it was still showing 8 ft of water so I knew it didn't make it in yet. After looking around for a while I spotted it. It would be better to have a lighter color top on this sonar. With all this adventure the battery did not get low.
One thing I noticed, using a line that sinks is not the best thing for using this sonar. I know a lot of people use braid but I find that a sinking line gets caught up in the weeds and does not allow the sonar to float out with the line attached. It would be much better in my opinion to use a line that floats like mono or a braid that does not sink. That way you can float this thing out without worrying about the line catching on the bottom. Only issue is you need a large reel to hold heavy mono line but it would be more useful.
