I created a couple of cheat sheets with meters to yards conversion on it to have in my pocket and also a cheat sheet with common language conversions. I’ll send you a pm later with that as someone here created one and shared it with me.
Warm clothes and boots
Don't overpack(ie heaps of food, cookers etc)
Be confident and firm with decisions around shooting.
With all guided hunts its the clients decision to pull the trigger. Only shoot if your confident.
Get close, you can stalk close in that country, same as anywhere else.
No reason to take a 500 yard shot if you can stalk to 250. Remember that.
Extra batteries for headlamps(and a spare torch) and batteries for rangefinder. The cold eats them up
