Hey Ben
For the last several years i have done most of my hunting walk and stalk, however i did play with a tree stand this last trip.
The reason is that it is very challenging, though sitting in a hide is fun and allows one to pick the right animal and the right shot, you are missing out on the real "hunt"
Africa on foot is wild, exciting and sometimes dangerous. The diversity of fauna and flora is unmatched and hunting walk and stalk is the way to truly experience it, take it all in.
Just about everything out there gets eaten and the game is wired 24/7 you don't find many stupid animals out there.
Terrain is a big factor, the open plains and grassland of places like Namibia can be impossible to stalk game in,
well nearly impossible...
i prefer the slightly thicker Acacia Velt, river beds are also a good place to stalk. Game trails are you friend in Africa, they allow you to move though the bush very quietly where they are worn down to sand. Try to keep to them as much as possible.
Use the terrain to your advantage, kopjie's are great for glassing.
Shoes..are probably the most overlooked mistake you need flat or crepe soles , the more tread the more noise no matter how you walk.
You have to have a good understanding of the animals habits and movements, the bush and a good bit of luck. You also need a lot of time, success rate is low.
You have to see the game before it see's you, once your are seen the stalk is over! 99% of the time.
keep your hands and face covered or camo painted they stand out alot.
