Let the scenario decide.
For those with mobility problems shooting from the back of the bakki or from a waterhole blind may be the only scenario to successful hunts.
Depending on your outfitter but hunting in RSA you most likely will be hunting multiple concessions for the various animals on your list. As such you will be going through gates......
OR
As you are riding around looking to spot a animal or rather a herd of the animal on your list, round a bend....
OR
Your stopped, standing beside the bakki trying to judge an animal on your list and....
SURPRISE.....a quality shooter or record book animal on your primary or opportunity animal list appears out of virtually nowhere at just feet or at very short yardage from you.
My Black Springbok, at 20 yards, as the tracker had just climbed onto the back of the bakki from closing a gate. We just moved down about 15-20 yards, set the sticks up, waited about 5 minutes for the springbok to intercept us, springbok down.
My Yellowtail Mongoose, my PH and I were trying to judge a Warthog at around 200 yards in the open when I caught movement out of the corner of my eye, just a couple of feet away from the front and side of the bakki, mongoose down.
My Gemsbok, we had been trying to get close to a herd of gemsbok in the open to get a stalk on. We tried coming up from behind them, we tried to use brush to conceal us on a side into the herd approach, finally tried a get ahead of and ambush, still couldn't get the gemsbok to cooperate for a shot. This went on for two and a half days without success. On the third morning made the shot. It was a good shot just not an instant drop. We followed the gemsbok at first on foot getting another shot, a trotting shot, into the rib cage. The gemsbok made it into a deep dry riverbed. The only way to get a vantage point to shoot before the gemsbok crossed onto a neighboring property was to make a shot from the back of the bakki down into the riverbed.
Another situation was a Black Back Jackal on my opportunity animal list. We were calling it a day, unsuccessful, hunting kudu when a Black Back Jackal came trotting out of the bush. PH stopped the vehicle, I got out of the vehicle, grabbed my rifle, thought I had a good scope crosshair alignment over the door, missed the jackal. Only jackal I have seen in 3 trips.
Not a hunt....A spot and shoot. Spotlight at night, road hunting from vehicle. Free non trophy animals...meat for lodge use. A Warthog and A Kudu.
Just presented various situations for hunting from a vehicle. That happened on my second and third trips.
My tracker and I also hunted from an archery blind at a waterhole near a carcass disposal spot in expectation of getting either a warthog or bushpig for lodge meat.
It comes down to the scenario, or the opportunity in which one is afforded whether to hunt from a vehicle or a waterhole.
For hunting it's about covering a vast area by using the bakki for spotting game, getting within several hundred yards into stalking distance, then start stalking on foot to within comfortable shooting distance, then making the shot.
