One of the most common questions asked by saddle hunters pertains to the use of Tree Climbing Spikes as a tree climbing method in a hunting situation. Climbing Spikes (also known as Gaffs, Hooks or Spurs) are devices worn on each foot which are equipped with sharp spikes (positioned near the ankles) which are driven into the tree with a downward kick. Spikes come in different varieties for poles (used by a Lineman) or Trees (used both Arborists). Climbing spikes were traditionally used with a Lineman’s Belt (or Buckstrap, Lanyard or Flipline) which goes around the tree/pole. In modern day, it is recognized that these devices are inadequate due to the lack of a cinching connection to the tree.

Tree Damage: Spikes puncture the cambium layer of the tree (under the bark), causing damage to the tree and risk of disease, which can eventually kill the tree. For this reason, arborists are not supposed to use spikes when pruning trees. See article: TCIA Article.
Dangers: Climbing spikes been involved in countless accidents.
- The primary risk is that they are prone to “gaffing out” (kicking out of the tree), causing the climber to lose balance, shift sideways, lose the spike other side, and fall, often grinding down the tree on the way.
- Used properly, with each step, spikes are driven into the tree with force, which is not a quiet activity. Because hunters strive to minimize noise, they may not exert adequate force in kicking them in, minimizing the puncture depth, and increasing risk of a gaff-out.
- Stability/bite is reduced in trees with scaly bark and wet conditions.
Legitimate Uses:
- By a trained lineman on a bark-less, wood pole, and only if used in conjunction with a “squeeze device” (not a lineman’s belt).
- By an arborist in tree removals, but not for use in pruning. See article: TCIA Article. Also, the climber should be tied into the tree ensuring that if a gaff-out occurred, the climber can recover.
- By trained professionals in emergency and rescue situations.
Legality: In most public hunting lands in the USA, climbing spikes are not legal for use. (Check with your local regulations.)
Bottom Line: JRB does not recommend the use of Climbing Spikes for Saddle Hunters. Remember: It doesn’t matter how we CAN climb a tree. It matters that we can do so reliably, repeatedly, and in adverse conditions with negligible risk of an injury or fall.
