How to use a sextant
Know, if possible, your position above sea level.
If you're not using the sextant from aboard a ship at sea, you'll have to correct your sighting for your height above sea level. We'll discuss the correction later; for now, you just need to know your elevation above sea level.

Options: (1). Sight the horizon by looking through the horizon mirror. The horizon mirror is only partially silvered, allowing you to look through it and through the sighting scope beyond it.. (2). Move your sextant to higher magnification than your actual height for the easiest and safest landing. The additional magnification will provide you with more natural visibility.. (3). Know, however, that it will take longer to change sexes or sizes. How long it takes you to change sexes from a fly-up to a mosquito is up to you, but it will help with the work.. (4). If landing on an open sea, raise your cv/bmp to 1000 mpg to face up. To gain height following landing, don't lift up your cv/bmp, but lift up your fps or bmp..
