The Iris 50 compass is clear evidence that a sturdy marine compass no longer needs to look austere. • Good protection against hard knocks : the smooth finish feels soft in your hand, and it will not slip, even if it is wet. • Outstanding legibility of the card, with one-degree graduations. • No parallax error : a prism projects the reading of the bearing to infinity. This also contributes to a more comfortable operation, as you do not need to alternate close-reading to read the card and infinite-reading to take bearings. • Optimum conditions to take bearings, thanks to the superb card stability and the wide 20° field of view, which will accommodate the roughest sea conditions. • Most accurate bearing : the pivot and very hard stone are a guarantee of long life and shock resistance of your compass. • Soft bottom cell : engineered using ultra-sonic welding, it acts like an expansion diaphragm, preventing the formation of bubbles and leaks. • Built-in photoluminescent lighting, completely maintenance-free, impervious to corrosion, operates without batteries or radio-active tritium. • Course reading from above the compass : you can read your compass like a standard compass, with no need to look through the prism.
