Not necessary and not recommended.
Any twit can press the 'go to' button on a GPS but recognising when 'go to' isn't 'going to' the desired place takes your navigation skill & judgement learned through experience.
The purpose of min. experience requirements - thus forcing you to hour build - is to consolidate & develop your skills, one of which is navigation.
Once your skills have developed then GPS devices can be great. They're not a navigation cure-all though.
