The 'bush flying' course, has nothing of real value to the prospective Maun pilot.
While you might learn a few handling techniques that will equip you for one or other situation in life, it is very far from what is required to flyin Maun.
Maun is regarded as bush flying only because there is bush around. You don't really fly in it.
Spend the money on a rating and maybe a few hours on type.
