- The Altimeter Plus Expedition Set model came with a leather case; a Maglite Solitaire; and a compass/level/ruler. This knife in this set included the back side fine screwdriver, tweezers, pen, pin, and eyeglass/jewelers screwdriver - US Model 53522.
This model became available in about 2000 and originally had the regular bottom scale. US model 53955 appears to be a later version with the new 'digital' bottom scale which holds all four scale tools: The removable ballpoint pen; toothpick; small tweezers; and straight pin.
The Altimeters are now withdrawn being replaced by the Traveller, which contains all digital functions (clock, timer, altimeter, barometer) in one digital unit.
