Won’t argue that reading and studying manual will help somewhat. BUT
When most basic of functions do not work properly ? In comparison these things cost a small fortune compared to the equipment of the near past.
My Helix 10 Mega suffered from p.p. engineering . I was able to get it to work by my trial and error. Starting with the Onix series. Humminbird in their rush to get new products to market. Have not tested their units to a level that insures out of the box operation. Solix is their top of the line yet it to suffers from intrinsic problems.
These problems have affected consumers of all levels of experience . Humminbird’s not fixing with prompt update is on their heads. Companies spend millions on advertising to attract buyers. Then when product fails to work as advertised. They drive them to another manufacturer.
Original owner’ s of Humminbird destroyed their rep. Johnson Outdoors, after buying ,worked long and hard restoring that rep. Now it appears they have embarked on that same downhill road.
Only time will tell if they come to their senses. If not they will suffer the same fate as Winchester Arms Co.
