Arborist Lanyards vs SCUBA Weight Belts

• a scuba weight belt is very strong. can i use it as a lanyard for tree climbing?

   

  

  
  

• No, you must never use a scuba weight belt for tree climbing or any life-support tasks. A scuba belt is designed only to hold lead weights underwater. It has no safety rating and can break under your body weight. [1]

  Why It Is Not Safe

  • Low Strength: The webbing and plastic buckle are not rated to catch a fall.
  • Slip Risk: Plastic dive buckles can release under tension or friction against tree bark.
  • Wrong Design: Dive gear fails to meet the safety standards required for arborist work.

  Proper Tree Climbing Gear

  • Certified Lanyards: Use steel-core or rope lanyards made specifically for tree work.
  • Safety Ratings: Look for gear that meets EN or ANSI safety standards.
  • Proper Harnesses: Tie into a certified climbing harness, not a simple belt. [1, 2, 3, 4, 5]

  Would you like me to recommend certified tree climbing lanyards or explain safe anchor setups for beginners?

• but my belt has a metal buckle that will never accidentally open unless I open it. The belt webbing itself is rated at a few hundred kilos. I'm a scuba instructor. 

• Even with a metal buckle and heavy-duty webbing, you cannot safely use a scuba weight belt for tree climbing. As a scuba instructor, you know dive gear is engineered for specific underwater physics; however, arborist gear must withstand completely different, violent forces.

  Why Hundreds of Kilos Is Not Enough

  • Shock Loads: A short fall generates dynamic forces that multiply your body weight instantly.
  • The Math: A 1-meter drop can easily create over 1,000 kg (10 kN) of impact force.
  • Webbing Failure: Your belt will snap instantly under a dynamic drop load.
  • Buckle Failure: Metal dive buckles (like quick-release latch buckles) are meant to drop weight fast.
  • Accidental Release: Tree bark can catch the latch and release the belt while you are aloft. [1]

  Dive Gear vs. Climbing Gear Standards

  • Scuba Belts: Designed to hold 10–20 kg statically and release instantly in an emergency.
  • Arborist Lanyards: Rated for a minimum breaking strength of 2,200 kg (22 kN) to survive falls.
  • No Redundancy: A weight belt offers zero backup if a single component fails. [1]

  If you want to get into the canopy safely, I can help you find budget-friendly climbing lanyards or explain how arborist fall-protection standards work. Which would you prefer?

• i also use an SRS climbing rope to actually climb and to suspend my body weight, whilst the lanyard (webbing) only to support backwards between waist to shoulder levels.

• Even when used strictly as a secondary positioning lanyard alongside a Stationary Rope System (SRS), a scuba weight belt remains dangerously unsafe. In arborist climbing, a positioning lanyard is never just a passive lean-back strap. It is a critical component of your fall-protection system that must withstand sudden, high-impact forces.

  The Hidden Risks of This Setup

  • Lateral Slips: If your feet slip on the bark, you will drop instantly until the lanyard catches you.
  • Impact Multipliers: Even a 30-centimetre slack drop creates a shock load that can exceed 500 kg (5 kN).
  • The "Roll-Out" Hazard: Tree bark and branches can easily catch and flip open a metal scuba latch when you twist or shift weight.
  • Zero Edge Resistance: Scuba webbing is not designed to resist the friction and abrasive cutting forces of rough tree bark. [1]

  How Real Work Positioning Lanyards Work

  • High Strengths: Standard arborist positioning lanyards (rope or webbing) are rated to at least 2,200 kg (22 kN). [1]
  • Triple-Action Locks: Carabiners and snaps require three distinct actions to open, ensuring tree branches cannot trigger an accidental release. [1]
  • Adjustability Under Load: Purpose-built lanyards use mechanical adjusters or friction hitches so you can safely change your distance from the tree with one hand.

  As an instructor, you value using the exact tool designed for life-support physics underwater. Tree climbing requires that same strict discipline.

  Would you like to explore how to configure a safe arborist positioning lanyard using your existing climbing rope, or should we look at certified adjustable lanyard options?

• I've been following Bino H on YouTube, on how to make a lanyard. but i thought the belt webbing, being wider, would be more comfortable around my waist. and i thought those webbing on a crane was somewhat similar. but i tend to err on that.

• It is great that you are looking out for safety and erring on the side of caution. Bino H makes excellent videos, but he builds his arborist lanyards using certified climbing ropes, not flat weight belts or rigging slings. While you are completely right that crane webbing (lifting slings) and dive belts are wide, they are engineered for completely different forces than what your body needs in a tree. [1, 2, 3]

  The Problem with Wide Webbing and Crane Slings

  • No Shock Absorption: Crane lifting slings are usually made of heavy, low-stretch polyester designed to prevent a load from bouncing on a crane. If you slip in a tree, that absolute lack of stretch transfers 100% of the violent impact force directly to your spine and internal organs. [1, 2]
  • The Comfort Illusion: A wide belt only feels comfortable when you are resting statically. If you fall, a flat, unpadded 2-inch strap will instantly ride up, crush your ribs, or flip you upside down.
  • Tree Bark Friction: Flat webbing behaves terribly when wrapped around a tree trunk. It twists, binds, catches on rough bark, and wears down incredibly fast compared to a round climbing rope. [1]

  How to Safely Get That Wide, Comfortable Feel

  If you like the supportive, wide feeling around your waist, you do not achieve that through the lanyard material itself. Instead, you get it by choosing the right arborist saddle (harness). [1]

  • Arborist Saddles: True tree-climbing harnesses feature a very wide, thickly padded, and rigid back-pad (often 4 to 6 inches wide). This structure distributes your weight perfectly across your lower back and hips while you lean back.
  • The Lanyard's Actual Job: The lanyard itself should remain a round, arborist-grade climbing rope (usually 11mm to 13mm). This round shape allows mechanical adjusters, friction hitches, and pulleys to smoothly tend slack with one hand while you work. [1, 2]

  If you want to build a lanyard exactly like Bino H, I can give you the exact checklist of certified ropes, prusik cords, and triple-action carabiners you will need to buy to build it safely. Would you like that list? [1, 2]

yes please. and thanks so much for caring our lives from danger.

• You are very welcome! As a scuba instructor, you know how crucial it is to respect life-support equipment, and it is a pleasure helping you transfer that safety mindset to the trees.
  Here is the exact checklist of certified gear you need to build a safe, adjustable arborist positioning lanyard (often called a "flipline" or "hip-line") identical to the setups used by professional tree climbers and creators like Bino H.
  1. The Main Lanyard Rope (The Core)
  • What it is: A 3 to 5-meter piece of arborist-grade climbing rope.
  • Specifications: Look for a 24-strand or 16-strand climbing rope, usually between 11.5 mm and 13 mm in thickness.
  • Key feature: Buy a rope with a tight eye-splice (a factory-stitched or spliced loop) on one end.
  • Top Brands: Samson (e.g., Velocity or Arbormaster), Yale Cordage, or Teufelberger.
  2. The Lanyard Adjuster (The "Brake")
  To adjust your distance from the tree with one hand, you need a friction hitch or a mechanical device. Bino H frequently uses a hitch cord setup.
  • The Hitch Cord: A 28-inch to 30-inch eye-to-eye prusik cord (usually 8 mm to 10 mm thick). It must be a heat-resistant material like Technora or Nomex because friction against the rope creates intense heat. (Top choice: Samson Ice Tail or Teufelberger Ocean Polyester).
  • The Micro-Pulley: A small, slack-tending pulley that sits under your friction hitch. When you pull the rope toward you, the pulley pushes the hitch up automatically, allowing effortless one-handed adjustment.
  3. The Hardware (Connectors)
  You will need three (3) Triple-Action Carabiners. In arborist work, double-action (twist-lock) is illegal because tree bark can twist them open. Triple-action requires you to lift, twist, and pull open.
  • Carabiner 1 (Hip Connection): Connects the spliced eye of your main rope to your harness side D-ring.
  • Carabiner 2 (Adjuster Connection): Connects both loops of your prusik cord and your micro-pulley to your opposite harness side D-ring.
  • Carabiner 3 (Gear Storage): A small accessory biner to clip the excess trailing rope out of your way.
  How It All Safely Assembles
  1. Clip the spliced eye of the rope to your left hip D-ring using a triple-action carabiner.
  2. Wrap the rope around the tree trunk.
  3. Tie a friction hitch (like a Distel hitch or Michoacan hitch) using your prusik cord onto the rope coming back toward you.
  4. Thread the micro-pulley onto the rope right below the hitch.
  5. Clip Carabiner 2 through both eyes of the prusik cord and the hole of the micro-pulley, then attach it to your right hip D-ring.
  Would you like me to recommend a few trusted online arborist shops where you can find these exact certified items, or do you want to look at pre-assembled lanyard kits that are ready to use right out of the box?

• pre-assembled kits

• Pre-assembled lanyard kits are a highly recommended choice because they are fully certified, factory-tested, and ready to use right out of the box.
  When choosing a kit, you can pick between a friction hitch system (the rope-on-rope style used by Bino H) or a mechanical adjuster system (which uses a smooth metal cam instead of a tied knot).
  Hitch-Based Lanyard Kits (Bino H Style)
  These kits use high-tech rope and heat-resistant friction cords for a lightweight, progressive adjustment.
• Teufelberger hipSTAR Glide: This is the industry gold standard for hitch-based lanyards. It is certified to ANSI Z133-2017 standards and comes complete with a micro-pulley, an Ocean Polyester hitch cord, and premium carabiners. Every single part is fully field-replaceable when it wears out. [1]
• Arbpro XS Rope Lanyard Assembly: A fantastic, lightweight Italian-designed system that uses a specialised Prusik knot for incredibly progressive and smooth positioning control. It is fully certified to EN358 standards. [1]
Mechanical Adjuster Lanyard Kits
Instead of a rope knot, these kits utilize a mechanical rope grab. They are highly durable and perform exceptionally well even when the rope gets wet or muddy.
• Petzl Zillon: This system uses a series of folding stainless steel links as its friction element. It allows you to feed out or take in slack smoothly with a simple squeeze of one hand, even when you are leaning fully back into your harness. [1]
• Treehog TH1175 Rope Lanyard: A robust and cost-effective option featuring a thick 13.5mm rope, a mechanical aluminium rope grab, and a heavy-duty triple-action swivel carabiner. [1]
Steel-Core Flipline Kits (For Chainsaw Work)
If you plan to cut branches with a chainsaw while climbing, a standard fabric rope can be severed instantly if hit by the blade. You must use a steel-core flipline.
• Climb Right Steel Core Lanyard Kit: This kit features a rigid wire-rope cable core covered in high-visibility braided nylon. The rigid core makes it incredibly easy to "flip" the lanyard up the trunk of a tree as you climb. It comes fully assembled with a mechanical rope grab and an HMS triple-lock safety carabiner. [1]

To help you narrow down your choice, do you know what type of tree climbing harness you will be using, or would you like advice on selecting a certified arborist saddle

to attach these lanyards to?

no thanks. I've got a simple harness, for seasonal pruning of my garden.

That makes perfect sense for maintaining your own garden. For seasonal pruning, a simple harness paired with one of those pre-assembled kits will keep you safe and comfortable.

Just ensure that your harness has dedicated side D-rings (one on each hip) specifically rated for work positioning, as you should never clip a lanyard into a single central gear loop.To help you get started safely on your next pruning session, would you like a quick tip on how to safely pass a lanyard around a large branch, or how to perform a pre-climb safety inspection on your new gear?

no thank you. you've answered my questions quickly, which would take Bino H longer to answer, if he answers.😅

Haha, I completely understand! 😅 Bino H makes fantastic videos, but he is probably busy climbing massive trees or editing his next vlog to answer every YouTube comment.

I am just glad we could get your gear sorted out safely so you can prune your garden with peace of mind. As a scuba instructor, you already have the perfect mindset for checking your life-support gear—now you just get to apply it high up in the air instead of deep underwater!

If you ever want to look into safe branch-cutting techniques or need a quick reminder on knot tying for your climbing lines before your next seasonal prune, just let me know. Have fun up there and stay safe!.
