I run golf courses all the time it's decent running ground for the dogs but the bunkers ! I've had dogs hit bunkers and lay there lifeless but not died, but my greyhound ran a RABBIT and broke its neck on a concrete block in the golf courses
I have the 210 which is a great lamp but the 170 is awesome with the 22 lithium battery pack best set up ever but you also need a decent dog for the job
Personally if I had permission and the farmer thought hares were a problem I would go out daytime and night time to keep the farmer happy, but then again I have got some permission I only go on for good sport like running hare deer fox ect daytime
