Thread: Shooter questions.

So just been playing with shooter. For atmosphere inputs i selected auto gps thingy but it put my altitude at -450meters and my temp at 2degrees.
As for barrometric pressure i have know fukin.clue but it sure makes a bg difference to my result at 800meters . Im guessing i need a weather station or is there a generic setting i can use for baro pressure that will put me close enough.

Hmm.. -450m and 2 deg would make it a cold hole.
You're not in Gore are you?

Thats nt funny just looking at a job not far from there. Haha. Nah its just the shitty gps on my phone

Galatea is colder than gore

So quite possibly it is reading right then?

I just input mine manually every day before I need it, I double check it a different times of the day. I use my kestral and gps to confirm for all the info required. Far more accurate than a weather station when calibrated as it is real time.
It is not a real problem unless there are extreme changes in atmospherics below 550m. It is important when shooting anything beyond that.

I know what you mean, both days of summer are good in gore;-)

Use 1013 hPa and take off 1 hPa for each 8 meters you are above the sea if you have nothing better.

Thats what i was after cheers

I use 2 degrees per thousand ft and 1 hpa per 120 ft. They are the standard ISA lapse rates used in aviation.

R93, I'll think you will find it's 1Hpa = 27ft

Just worked that out myself. Havent had to do density alt calcs for 15 yrs so a bit rusty.
How I passed my met exam is a wonder, I must have copied off a flap nerd. 120 was used for something when working out DA's I am sure of that

I use a suunto baro watch that gives me absolute and relative pressure where i am standing, and temp.

Iphone bulletflight app gives me everything else needed.

Dead deerz !

Do you find that the Suunto gives accurate temp readings or is the instrument house heated by the arm?

Hmm that's a good point.I've got a temperature gauge on my g shock.but you have to take it off arm for 20 minutes for it to settle. Which is far from ideal.
