Sig Kilo 10k Gen 2 compass question

[Sebrock]

Does anyone know if the compass gives true north and adjusts for declination based on location coming from phone? If not, how do you adjust manually? For my 6.5x47 at 1000 yards, my -11deg declination is .2 mils of elevation difference which is a lot for smaller targets

Man, that is deep into the weeds.

Not really - if someone was thinking of ditching the Kestrel (where you take magnetic reading and manually adjust) or Phone App (which gives you true north) for these then they are going to miss small targets at distance. .2 mills doesnt sound like a lot but its 8 inches of elevation at 1000 yards where I generally shoot. Maybe not an issue for hunting since its at shorter distances, but on longer range PRS or sniper matches, doesnt give a ton of confidence if they dont use true north (which is what the spinning of the earth is based on).

Not able to answer your question,BUT doesn’t a compass read magnetic north and not true north. As a sidenote I have a compass that reads south as north. Wasn’t always like that. Swapped directions about 5 years ago. Didn’t throw it away but can’t find it.

A real compass points to Magnetic North since it is dependent on the magnetic field (which moves around). The declination then lets you adjust to True North which is the norther most axis on which the earth spins. It's important for Coriolis Effect because it doesnt spin related to magnetic north but the axis of the earth. The compass on your phone for example, lets you chose either option. If you have true north selected, it will adjust for whatever declination is wherever the phone is located.

Generally, yes... but most half-way decent civilian models have some form of adjustment for magnetic declination. With the old military lensatic compasses (dunno what they use these days) the user had to do that themselves. Depending on your location, the amount of correction can be significant.

Talked to Sig. It’s true north as it should be. Confirmed with my iPhone as well as my Camega which was off by the declination here.
