Sounds good. I was just about to post 'What Constitutes a Fair Hunt ?'. Ideas vary.
To me it is:

Tophets Fair and Ethical Hunt.

Driving to a locality,
Getting out of the vehicle,
Carrying everything you need for however long (A Day),
Go looking for game on foot.
No spotlighting except for Varmints.(Need to define Varmints).
Shooting on dusk ok.
Shooting after dark ok.(eg if a full moon with superior optics)
No Illuminated reticles or scopes.
No use of night vision devices.
No use of traps. (Need to define Trap eg mechanical device such as fence).
No use of Baits. (Need to define Bait eg dead animal or feed left in known location).
No shooting of animals bred in captivity. (Need to define Captivity eg hand fed, reared from birth, or kept in an enclosed space).

In the high dollar/short time frame, world of International hunting all the above may not be appropriate. In the paid hunt situation problems may arise in the following areas and would need to be considered and defined by both parties.

Non use of baits would limit hunting of nocturnal species. (eg the Cats)However returning to a kill made by a predator at a later date maybe appropiate.
It may be more appropriate to spot game and then immediately dismount from a vehicle for a short stalk.
The area used for hunting would need to be defined. What constitutes free range ? (A fenced area of 60,000 acres may be defined as enclosed just as a 2 acre area is enclosed, if bred animals are introduced to the area immediately prior or for the hunt.)
How do you know you are not shooting a bred animal ?

I'd also like to say that I do not always engage in fair hunts as defined above. I have never shot a bred animal and hope I never do. I have shot introduced animals (Pests) over baits such as feed blocks. That is not a fair hunt, just extermination.

Some point for thought.
