If you get lost on the adjustment graduations, turn the adjustment knob all the way down till it stops. Come back up to zero. This is your 100 yard zero. Now you can start over.
On pack ice...the suns rays and heat are reflected off the ice. On seawater...the suns rays and heat are absorbed. That is why it is so easy too see wind mirages over pack ice.
