Navigation circle
Navigation compasses are a specialized subcategory within navigation accessories, designed for traditional nautical navigation—for measuring distances, transferring distances, and working precisely on paper nautical charts. Navigation compasses are part of the basic equipment for boat license training (e.g., SBF See), for recreational and commercial boating, and as a reliable backup in case electronics fail.
Our product range (subject to availability) includes brands such as Ecobra, L’Ocean, and Topoplastic. Brand names remain unchanged—important for consistent quality, availability of replacement parts and tips, and the familiar handling during training and in practice.
Select your compass based on design (one-handed/spring compass, straight/curved), length (typically 20–25 cm for training and onboard use), and material (brass, chrome-plated/nickel-colored, Zapon-coated). A smooth-moving joint, cleanly guided tips, and a good grip are key to measurement accuracy and comfort—especially in rough seas or when working quickly in the cockpit.
- Design: One-handed compass for quick work; classic chart compass for precise marking on large charts.
- Accuracy: play-free joint, cleanly ground tips, sturdy arms – prevents measurement errors.
- Material & Environment: Corrosion-resistant surfaces and robust mechanics for salt air/moisture on board.
- Handling: non-slip grip, good tension, secure storage (folder/case)—so nothing bends or goes overboard.
Examples from the range: Ecobra one-handed chart & navigation compass, chrome-plated brass; Ecobra one-handed marine compass, polished brass; Ecobra straight chart compass (matte nickel-colored); Ecobra chart compass, zapon-coated brass.
FAQ
Which compass model is best for training and onboard use?
For training and exam tasks, a precise chart compass with a play-free joint is ideal. Those who want to quickly measure distances on board (e.g., in the navigation table) often opt for a one-handed compass because it opens and closes more quickly. It is always important to have sturdy arms and tips that “stand” firmly and do not slip.
What length makes sense (20 cm, 25 cm …)?
For many nautical charts and training situations, 20–25 cm is a very practical standard. A larger size can be advantageous on large charts; a smaller size is more compact but sometimes less convenient for measuring longer distances. If you primarily work with training or standard charts, 25 cm is often a good all-around choice.
How can I tell if it’s high quality—and what should I look for when buying?
Look for a joint with no play, consistent tension, cleanly finished tips, and sturdy arms. The compass should be adjustable with precision and hold its setting without “giving way.” Corrosion-resistant finishes (e.g., chrome-plated, Zapon-coated) are a plus on board.
What kind of “compatibility” is important for a navigation compass?
With compasses, it’s less about technical connections and more about practical compatibility: does the compass fit the chart size (working area), meet training requirements (e.g., SBF Sea tasks), and fit for storage (folder/case in the navigation kit)? If you already use a navigation folder, it’s worth choosing a compass that matches its length and design.
How do I use the compass correctly to measure distance?
Distance is traditionally measured on nautical charts using the latitude scale: Mark the distance with the compass and transfer it to the lateral scale at the appropriate chart width (same width/similar latitude). This prevents reading errors that occur when you accidentally use the wrong scale.
Care: How do I keep the navigation compass accurate over the long term?
After exposure to salt air or moisture: wipe with a soft cloth and store in a dry place—ideally in a folder or case. Protect the tips from impacts (do not store loose in a toolbox). If necessary, gently clean the hinge; avoid harsh cleaners to preserve surfaces and coatings.
Common mistakes when working with maps – and how do I avoid them?
Common mistakes include “wandering” compass points (insufficient tension), measuring on the wrong scale, or a bent compass. Before starting a task, briefly check the tension, measure distances using the width scale, and store the compass in a protected place. This improves accuracy and saves time—especially during exams.
