Has anyone here had any experience with the Brunton 8099-Eclipse Sighting Compass?

Also, where in South Australia would this be available?

Cheers

G'day Willem.

Yes, it does have a compass, but it only works whilst you a moving, as you know.

Here's the thing.....

I am one of those people who has never been satisfied in just simply turning something on, or operating something to get a result.

I always want to know WHY it works, it's history, can it be improved, etc....

Enquiring mind.....

So, one thing became patently clear to me before my purchase of a GPS. It is an AID to navigation, not the cornerstone. Okay, some people use it as the main device, and that's okay, but I want to go a bit further.

After reading Len Beadell's works, and realizing how important good navigation skills are, I decided that I want to learn how to navigate WITHOUT the GPS, simply by using a good sighting compass & maps. I believe that learning this skill will be damn good fun, and may one day be of benefit.

On the net, there are some good sites pertaining to how some of the WW2 soldiers navigated in the African deserts, mind blowing stuff indeed.

I will still use the GPS, but hopefully, only to check my co-ordinates after I have taken some bearings.

One thing Will. I would like to know more info on how you guys navigated to the centre of Australia, because that would be interesting reading for all.

Ahhh those sweet Silva days WIllem I too have one in the car, and its helped me out a number of times, once in the Great Vic Desert, when we had gone a long way down a track I pulled out the trusty Silva and with a couple of landmarks set off in the right direction.... Much to Marie's amazement!

What do you need a sighting compass for? Are you always driving blind or at night LOL surely the old prismatic or silva is good enough. Are you getting a sextant too?

Lucky I getbleepevery night, or I'd be out sussing the stars as well, like Len Beadell did!!!

One interesting thing.....

Thor Heyerdhal, who was a Norwegian explorer ( Ra expeditions ), cottoned on to something interesting.

Instead of using a sextant, he mad up a Nase - Ometer, which was a copy of what the Egyptians probably used during their sea-faring voyages. this is quite a feat, considering that the Phonicians, who were the prime sea- farers, would have had to have compiled some vast tables, so as to be able to use the knowledge of sun bearings, and let's not forget about time keeping!

All good fun anyway.

Cheers

Homer Simpson used one of them Nase-Ometers Wolfie, when he was adrift with Bart & Ned and Rod Flanders. He smelt a trusty Krusty burger outlet on a nearby oil rig hahahahahaha

Lenny Beadell is such an inspirational writer and Australian isnt he? Going to Woomera in April on the way home from the Simpson, have read ALL his books and seen his Videos (available from the EO shop) and boy did I want to be there in the LandRover bashing the road thru to open up Central Australia.

Bush Dentistry in deed!

Whitworths, the marine suppliers have a number of hand held compasses for taking bearings. I find that the electronic fluxgate compass is easy to use and as it has a memory, can memorise a series of sights for transposing on to a map or chart in order to fix your position. Some hand bearing compasses can be dashboard mounted as well for use while driving.

Yeah Wolfie I was about to suggest a marine store. When yachting I used one which was built into a rubber tyre-like edging. The whole thing was about 100mm across and 35mm deep. Had a built in prism and worked well.
Books on yachting usually have sections on nav.
Watch out for stray iron or electric currents when you use your new toy 'cause it will deflect the needle. Even some glasses frames can do this.
Cheers,

Glasses frames.......

Would that mean that if I choose a sighting compass, or lensamatic, I will have to get a diopter to compensate?

Wolfie,

For years I used a similar unit, that we purchased from an Instrument supplier in Melbourne, now out of business. Did heaps of surveys, angles, the lot, only once did a power pole end up on the wrong side of the road, and that was only on a drawing.

In the end I found that I was standing back to a pole with earth cables running down it and the electric field was playing havoc with the magnetic field, stood 5 m away and carried out a parallel survey and the pole magically moved to the other side of the road, very polite of it I thought.

Bonz, were you a surveyor?

This is something I have been meaning to read up on, like just the basics..... sort of surveying 101 or something. It has always interested me how when they come and survey your block of land, and the survey peg is around the other side of the street, they can still suss it out.
