all above is great advice ,with a climber ,be sure you have the stand at the bottom of the tree at an angle,not straight,also be sure you have them both connected with a rope or some thick string ,my oldest brother had a new ol man some years ago and we were in the backyard and he was going up and down to get a feel for things,he put the stand at the bottom of the tree straight,he got up about 15-20 feet and set down and the bottom part slid down the tree ,he also forgot to connect the top and bottom together!i had to run and find a ladder long enough to get him down!! ..be careful..
