Yes.
I'm afraid to ask how much that puppy was. Even used and decertified, the Trimble gear is pricey.Why not? I have a Raymarine 420 with no cartridge in the pilothouse, but I keep a Magellan handheld of some antiquity at the sailing helm for quick reference. I even have a 1993 Trimble aircraft GPS with a two-line display as a backup to the backup (it's built like a tank, acquires as fast as a modern GPS and has an excellent mounting clamp).
