The Explorer is Ritchies most popular series of compass.
This flush mount model provides a secure, low-profile installation, excellent dial visibility, and minimizes the effects of hull or engine vibration.
On powerboats, this flush mount Explorer is used on fishing towers, fly bridges, bridge decks and center consoles.
On sailboats, it is often mounted on side decks, or on pedestals with a binnacle adapter.
