I have hunted Africa a number of times. Never managed a Leopard, although tried twice over baits. Nearly all Leopard hunts, to my knowledge are over a bait. There is NO gaurantee of success.
Some years back Botswana allowed you to hunt Leopard on foot in the Kalahari, using Bushmen trackers over a day or two or more. In most instances the Leopard charged, and there were some interesting stories abound at the time. However to my knowledge this has all been stopped for sometime.
I was not aware that anyone could use thermal to hunt at night in Africa, maybe the laws have changed. If this is the case I would add this is not hunting and in my opinion should not be allowed.
You pit your wits against wild animals, some considered dangerous game, you rely on the skills of your PH and more importantly the trackers. This is the essence of a true hunt and safari. Driving around in a 4x4, shooting out of the vehicle and using an night imaging to kill is not hunting in Africa, and a number of safaris these days can be nothing more than drive around a fenced area, sometimes huge, sometimes not so, in SA. And its all about which animal you want to take off the menu. Or how many Impala you want to cull off the farm.
Either way Africa has never been cheap, although these package hunts for 7 days, and shoot cull Springbok or Impala seem to be some peoples choice, and within their budget.
Not for me, I would rather go once in several years and take 2 or 3 well earned animals, and enjoy the whole experience, and work hard to get the shot, if I don't, well that's hunting. Without a thermal.
I might add that just about all my visits to Africa were in the 1990's and just into the 2000. But I have hunted Botswana (when you could, on concession) Zimbabwe, Cape, Transval, Zululand and the Drakensburgs.
