Skipjack68, You know we are all about reliability and customer service. In 2008 Model Year we went with HB units as standard equipment. We sell both units and while we were well over 95% Lowrance, we are now mostly HumminBird. WE have had limited HB issues, though VERY limited. As for mapping and reliability, the GPS on Lowrance we like, though the units are easier to function on HumminBird units. Both have their features and if the choice is function then you need to decide that.
