AMGA Single Pitch Instructor (SPI)

Using a static rope to build an extended anchor allows the master point to sit over the edge, preventing the dynamic climbing rope from rubbing against the rock. Extending a dynamic rope directly causes severe friction and edge damage, while keeping the master point high creates dangerous rope drag. Using multiple connected runners is inefficient, highly tedious to equalize, and introduces unnecessary points of failure.

Tying a catastrophe knot in the brake strand is the critical first step because it secures the system against catastrophic failure before any load transfers occur. Transferring the load or swapping devices without a backup exposes the client to a potential ground fall if a mistake is made. Relying on an unvetted bystander to hold the brake strand violates fundamental risk management principles.

A plaquette-style device in guide mode attached to the master point provides an auto-blocking belay, reducing instructor fatigue and allowing hands-free capability if an emergency arises. Redirecting off the anchor increases friction and upward pull on the instructor, making it less efficient. Belaying unanchored near an edge or using a Munter off the harness without a redirect are severe safety hazards.

Locking off the device and setting up a mechanical advantage system (like a 3:1) safely unweights the entangled area so the hair can be carefully removed. Cutting hair should only be an absolute last resort, and lowering rapidly will forcefully pull the hair into the device, causing injury. Relying on the client to pull their own weight is unreliable and could worsen the entanglement if they slip.

The AMGA SPI certification strictly limits instructors to single-pitch terrain where the base or top is easily accessible without multi-pitch techniques. Multi-pitch climbing, transitioning between intermediate belay stations, and complex alpine environments require Rock Guide or higher certifications. Leading a single pitch to set a top-rope and managing 3rd-class access are within the standard SPI scope.

An extended rappel with a third-hand autoblock below the device allows the instructor to stop hands-free to assist the client while keeping the backup out of the device. Placing a backup above the device can cause it to lock up out of reach under tension. Using a non-locking carabiner for a rappel or rappelling without a backup during a rescue scenario are unacceptable safety risks.

Anchors must be unquestionably solid; trees with shallow roots in loose soil do not meet the criteria for a primary anchor component, regardless of equalization. Tying off high actually increases leverage and the likelihood of uprooting the tree. Padding protects the tree’s bark but does nothing to solve the structural weakness of the root system.

No Extension ensures that if one arm of the anchor fails, the master point will not drop and dynamically shock-load the remaining components. Using non-locking carabiners at the master point violates safety standards, which require locking carabiners. While natural anchors are great and angles should be narrow, the ‘N’ in EARNEST specifically refers to No Extension.

A simple 3:1 Z-drag can be built quickly using the existing rope and guide mode setup, providing enough assistance for a conscious client to pass a crux. Building a complex 5:1 with separate ropes is time-consuming and usually unnecessary for simple top-rope assists. A counterbalance rappel is a highly complex rescue technique reserved for incapacitating emergencies, not minor climbing struggles.

Consolidating gear on durable surfaces minimizes the environmental footprint and allows other crag users to share the space safely. Spreading gear out or altering the natural environment by clearing vegetation directly violates LNT principles. Hanging heavy gear on trees can damage bark and branches, negatively impacting the local flora.

Using backup belayers keeps waiting clients engaged while providing a critical safety redundancy for novice primary belayers who might drop the brake strand. Letting clients wander unmonitored reduces group control and increases risk. Tying the brake strand to an anchor eliminates the dynamic nature of the belay and is not an accepted top-rope belay technique.

The flat overhand knot (often called the European Death Knot) is preferred because its flat profile naturally rides over rock edges, drastically reducing the chance of the rope getting stuck when pulled. A square knot is unsafe for joining life-supporting lines, and a water knot is intended for tubular webbing, not dynamic ropes. The bowline on a bight is a loop knot, not a bend used to join two ropes.

SPIs must manage their own exposure to falls by utilizing a secure tether line or personal anchor system whenever working near an exposed edge. Relying on balance or a seated position does not eliminate the catastrophic risk of a slip. Using a novice client as a human anchor is highly dangerous and unprofessional.

An optimal cam placement requires the lobes to be in the middle-to-tight portion of their expansion range (50-90%) with uniform contact on parallel or slightly constricting rock walls. Tipped out cams are highly likely to fail under load, while over-cammed devices may become permanently stuck. Placements in outward flaring cracks are inherently unstable and prone to pulling out.

Passing a knot requires transferring the load to a friction hitch (like a prusik) so the belay device can be safely unweighted, moved past the knot, and re-engaged. Forcing a knot through a device is impossible, and untying the isolation knot exposes the damaged core to a life-bearing load. Having a client untie while suspended is a fatal error.

The fundamental rule of belaying is that the brake hand must never leave the brake strand; if it does, the system cannot arrest a fall. Posture is secondary to hand placement, and the guide hand’s position fluctuates as rope is pulled. Belayers should watch the climber to anticipate falls and rope needs, not stare at the device.

Hearing thunder indicates that lightning is close enough to strike, necessitating immediate evacuation to a safe structure or vehicle. Waiting for visible strikes or a time delay needlessly exposes the group to life-threatening danger. Standing under tall trees is one of the most dangerous places to be during a lightning storm.

A tied master point (like a BHK or figure-eight on a bight) fixes the equalization, creating a completely non-extending system if an anchor leg fails. Unlike a sliding X, it does not self-adjust to off-axis pulls. Locking carabiners are always required at the master point of a top-rope anchor, regardless of the knot used.

Lowering the client allows the instructor to properly clean the wound, prevent bloodborne pathogen exposure on the equipment, and assess the client’s mental state. Pushing an anxious, injured client to continue can lead to panic or further injury. A minor scrape does not warrant emergency services, but it should not be ignored.

The SPI is responsible for the safety of the site, which includes mandatory visual and tactile checks of all life-safety equipment and knots before a client leaves the ground. Trusting a client’s self-assessment of experience bypasses critical institutional risk management. Instructors must evaluate all gear used, whether personal or provided, but do not require clients to buy new gear.
