Hey Kal, welcome! the later the season...late August, Sept even into early Oct are great times to bowhunt. The late season gives you better visibility and more action at water points! July in SA is bitterly cold in a lot of places!
Book your hunt, but don't part with your hard earned money til the last moment!
Read your contracts well and understand them!
Get to meet other clients that have hunted the same place!
If you book at a show (SCI or DSC) or similar, hang around as the old clients love to pop in a shoot the breeze!
Research a lot!
Enjoy!
