Sun shade for Helix 7 is a good product. Additionally, RipaLip App for fish finders has been very useful. Some say that it simply provides a lot of information that is already on the internet, and to a degree this is true, but the app goes further, allowing you to easily access quick start guides, advanced guides, videos, AND save notes about settings used for different bodies of water. Why rely on google searches when you can have it all in one App. RipaLip owner is very helpful when it comes to any questions regarding products.
