Compared with the original Navtronic Explorer introduced in the year 1983 this 1987 built Explorer feels cheaper.

The original Explorer uses solid keys instead the later rubber keys and got the name in the mold instead of a cheap sticker. The inside of the products shows the real difference, the solid metal plate to support the keyboard was removed.
