Filters should be darker

Filters should be darker. The sun is still very bright with all the filters in place. When you look at the sun with filters in place, your eyes tire quickly and it takes a few minutes to restore normal vision. I have made many observations of the sun with a geodetic total station with the filter in place and have not found the sun to be anywhere near as bright as this unit. I think filters should offer the same shade as number 10 welding safety glass.

Pros
  • Marine GPS Accessories
Cons
  • No Power

The first user is suitable for marine GPS. Accessories

I've never used a sextant, but I've always wondered if I could tell my position from the sky. My first line of position after getting used to the sextant and the artificial horizon seemed fine to me, but I'm sure I'll improve it. I haven't had good sun since I did the first LOP, so I don't have a "solution" yet. However, by logging the LOP and GPS location of my cell phone, I can be within 6 miles. Not great but this is my first experience. I have a few suggestions for Davies: 1) Add sketchesโ€ฆ

Pros
  • Car electronics
Cons
  • Some difficulties

Surprisingly accurate and inexpensive! โ€“ I can ship you all over the world

First the bottom line. You can't go wrong with this Davis Mark 3 sextant or artificial horizon. The Mark 3 is a fantastically well thought out design that makes the most of the technical properties of the plastic. 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 averagingโ€ฆ
