The trend in multifunction displays is weighted toward touchscreen models, simply because these are easier and faster to use. While most boaters have accepted touchscreens, some still prefer buttons and dials. You will find such old-school models on the market; Si-Tex and Humminbird both offer a number of non-touchscreen displays. Another solution is an MFD that offers both systems. The Lowrance HDS Gen3 series, for example, augments its touchscreen user interface with a full-function keypad. Auxiliary keypads are also available to control dedicated touchscreen models. Raymarine’s RMK-9 remote keypad, for instance, allows control of its touchscreen MFD via buttons and a dial.
