I am a certified Hunter Education instructor for the state of WI. Been doing this over 25 yrs. WE are required to teach Tree Stand Safety.

Safety and Hangon stands.
ALWAYS have your climb in ladder you use to get into your hangon stand with ladder rungs higher than the foot platform of your stand.
ALWAYS STEP DOWN into the hangon stand platform and make sure you step in the CENTER of the foot platform. This places your weight on the stand and creates a weight fulcrum which keeps the stand in place.
Stepping down into the center of the foot platform you should still have 3 points of contact with the ladder. That means 2 hands, one foot still on your climb up ladder and then ease your weight to your platform foot rest.
ALWAYS climb up and down from your stand keeping 3 points of contact with your ladder.
ALWAYS use a qualified Fall Restraint system.
ALWAYS use a Life Line while climbing up or down from your stand.
ALWAYS insoect your tie down straps used to secure your stand. Any fray or wear replace.
NEVER jump up and down on the foot platform.

Hangon stands are popular.And they are easy to set up.
I also use an extension ladder as mentioned.

A few other comments.
Do read your state regs. Some hangon stands use a screw in peg and on public land in my state that is illegal.
You can't screw anything into a tree, nor cut branches dead or alive to create shooting lanes. So be careful.
AND ALWAYS use a live tree.

TREE STANDS of all types is the number one cause of hunter related accidents.
