Although others have probably already said it, a trophy eland is not an easy hunt.
If you are lucky you may find a good one with a group of cows in which event finding it will be quite easy. However big bulls are frequently solitary and they prefer to stay in wooded or bushed terrain - i.e. not often out in the open in bush country. This being so, the best strategy is usually to look for good (read "big") fresh spoor on a road/track and then try to sneak up on it. Most of our hunting here is on ranches varying from 1000 - 10 000 ha and one might be tempted to think that finding an animal this size on say 5000 ha would be fairly simple. However they are like ghosts. On one ranch I hunt regularly there are two known bulls in the 1 Ton class. They were spotted on a couple of occasions last season but no-one got a shot. This season they haven't been seen at all. They may have died but judging by spoor I would say that they are still around - just not showing. The fact that the bush has been particularly thick this year has not made things any easier.
The best country for hunting them successfully is open Savannah as you can spot and shoot from a distance.
They also occur in grassland areas, in our country frequently in mountainous terrain. There the challenge is getting sufficiently close as they have good eyesight and will more often that not trot off before you can get withing comfortable shooting range.
An interesting thing about an eland is its ability to jump. It easily clears a 6' fence without a run up. In fact they can jump higher - which is amazing given the size and bulk of the animal.
Although no-one has specifically asked, note that Eland are best hunted with fairly heavy calibres (.338Wm, .375H&h etc.). Its not that lighter calibres wont penetrate (they do) , but rather that you want a lot of shock and big permanent wound channel. This is especially true in bush terrain , where the objective should be to "pin" the animal
