Seaplane Training, KSN770 Counterpoint, Narco Avionics Support

I read with interest your coverage of seaplane transition training in your last issue, since Im planning on earning my rating to transition to the Glastar amphib Im building. I was surprised how gently Aviation Consumer treated a product that has been promised for years, has been offered for sale since 2014, yet has so many major shortcomings. I wish you guys would write another report on servicing old avionics. It seems there are many in service that need repair.
