An innovative avalanche accessory providing vastly improved performance over the traditional knotted rope and producing effective snow profiles with minimal effort.
Manufacturer: G3


Lightweight cable is virtually indestructible
Low profile swage springs slice through snow and ice with minimum probe wear
Large loop handles can be used with gloves or mitts
Bright red cable can be bull whipped for traveling in white out conditions

5.75m / 18.8ft = 77g / 2.7oz

Rutschblock Test

Use the G3 Rutschblock Cord as an aid for emergency travel in adverse conditions. Ensure one end of cord is attached to the clip inside the storage bag, then fill the bag with snow. With a firm grip on the loose cord handle, throw the bag toward the desired direction of travel. The red cable will assist by highlighting slope changes within ~6m (19ft).

The Rutschblock (or ‘glide-block’) test is useful for identifying potentially weak layers throughout the snow pack, which are easily triggered by skier weight. The Rutschblock site should be safe, representative of the avalanche terrain and undisturbed. Place two probes into the snow 2.0m (6.5ft) apart and angle them into the slope (to facilitate cutting). Measure ~1.5m (5ft) down-slope of the probes. Dig out the front of the block below any concerning layers (identified in your snow profile). Loop the G3 Rutschblock Cord behind the probes and have one person grasp each handle, hold the handles 2.0m (6.5ft) apart and saw back and forth until the cord is below any concerning layers. To conduct the test, approach the block from above, step onto the block and apply force as described. Record required force to produce failure.

NOTE: The cord may mark some surfaces. Be cautious with softer composite poles.

Based on a slope greater than or equal to 30 degrees

R1 Slides during digging or cutting.
R2 Slides during approach or step onto upper part of block (step within ~35cm (1ft) of upper wall).
R3 Slides during knee bend (do not lift heels, push down).
R4 Slides during first jump (same spot as before).
R5 Slides during second jump (same spot as before).
R6 For hard deep slabs remove skis and jump on the same spot. (for thin or soft slabs keep skis on, step to middle of block, do one knee bend, then jump up to three times).
R7 No definitive failure on a defined plane.
