🌊 Precision Navigation Tool: Davis Marine Sextant - Enhance Your Nautical Adventure Review

We have just completed our Home School Introductory Celestial Navigation Course for grades 8-10. This sextant was a required purchase for the class. It's easy to use, clean, easy to set up for accuracy and the booklet that came with it was very helpful. The class met once a week for 8 weeks. By the end of the session, all students knew how to look at the sun, the moon and about 15 stars. With this sextant, they could calculate the error of their index very easily. None of the students had an…

I have seen criticism from those formally trained in navigation, but such criticism is beyond my knowledge and use of the product. As a layman, I didn't notice any significant flaws. It worked as expected to my complete satisfaction. DO NOT BUY ANYTHING CHEAPER THAN THIS. (The $12 sextant I found at a local hardware store was DECORATIVE ONLY, despite the misleading words on the labels and in the instruction manual describing it as "working".) The filters attached to this sextant so they are not

I have had a very mixed reaction to this product. On the one hand, it's a very affordable, useful sextant. On the other hand, it often has a serious disadvantage - the horizon mirror (below) is often shifted and cannot be adjusted. When you look through the eyepiece, the right side of the horizon mirror simply reflects the side of the sextant. Only the left side of the horizontal mirror reflects the image from the straightening mirror. The horizontal mirror must be perfectly perpendicular to…

was interested in celestial navigation and studied via youtube and the internet - used a Mark 3 sextant for practice. there is no better alternative at a reasonable practical price with good accuracy. I've practiced with an artificial Davis horizon (but you can make your own as it's just a reflective liquid (like water) sheltered from the wind). I used the calculated altitude via the app (the estimated position is my GPS position) and can get an average accuracy of 2 minutes (equivalent to…

First the bottom line. You can't go wrong with this Davis Mark 3 sextant: it's a fantastically intelligent design that makes the most of the technical properties of plastics. How amazing that a $50 set can compete with traditional metal sextants like the Astra IIIb that cost 15 times more. When photographing the Sun, Moon, or Venus from the Davis artificial horizon, I typically get a line of reference within 5 miles of my coastal location. . The averaging of several oscilloscopes reliably leads
