I am not familiar with the Hook seven. If it has a SD slot, then U can/should be able to run maps from the SD. May be slow loading and updating map positions (lag) based on the processor speed. You can buy maps, Insight and hot spot maps, etc. Depends on what lake U looking for. Small lakes will probably not be shown or be a blue spot on the map.
