[Rhodes22-list] Bob Dilks Sextant

Davis MK 25 sextant

Comes with instructions.

Taking a LAN on the beach is easy. On a boat harder.
A LAN ( local area noon) sight only gives latitude

real celestial navigation is easy in theory, but time consuming in practice.
Of course using a computer simplifies things.....:)

You need about 3 miles of water to get a horizon for a sight. Or there are other tricks you can use.

So even on a Tennessee lake I take sights.

	What is the brand of this plastic sextant.  Does it come with
instructions?  How are going to use it in Tennessee?

Sextant   Absolutely
I own a $200.00 plastic sextant.
I have all the books and tables to do celestial navigation by hand.
When I go to the beach I have had strange looks as I do a LAN sight.
Plus it gives me a reason to re-learn the stars.

Using the sextant in real conditions is a challenge.

One interesting thing, A cheap TIMEX watch makes an excellent
chronograph.

I have an HF radio and can monitor the time chits on 5 MHZ for time
corrections.

Great Fun

Vic:
Almost everyone that is in the same line of work as myself (Marine
Science) 
owns and/uses a GPS of some sort. Judging from the last posts regarding 
this (GPS), most small craft (rhodes) owners probably keep (and use) one
as 
well....it's just that they (we) realize that electronics can and do
fail, 
so although we probably tend to utilize them as a "first line" (out of 
ease/laziness), we are also well versed (usually from the start) in the
art 
of dead reckoning, chart navigation and other "classic" less technology 
dependent resources, concurrently utilizing that as well when we voyage.

BTW sometimes I still practice the venerable "noon shoot" (no Rummy, not
a 
shot glass of Mt. Gay at noon, although I do ascribe to your additional 
survival technique) when working offshore....anybody else out there use
a 
sextant?
