Depth System

 

Maximum Typical Error

5%

Maximum depth error for a layer location as a percentage of that layer’s depth. Dependent on good probing technique and appropriate snow conditions


Mean Error

2.3%

Average depth error for a layer location as a percentage of that layer’s depth


Force System

 

Hardness Resolution

3 kPa

Scope can differentiate between layers with a hardness difference of 3 kPa or greater (mean F - 4F kPa difference is about 60kPa, so the scope force resolution is much better than hand hardness tests or the Ram)

Minimum Identifiable Layer Thickness

1.5 mm

 

Temperature Variability

0.2%/degree C

 

Hardness Range

3-550kPa

The Snow Scope will always identify relatively hard or soft layers as thin as 1.5mm when there is a significant hardness difference (1 hand hardness jump or greater). For layers that are very similar in hardness, 7mm is the repeatably identifiable minimum layer thickness

 

Force values will fluctuate a maximum of 0.2%/C on an absolute scale (they should not change relative to each other, so snow structure will not be affected)

 

Scope can read snow hardnesses between the low - middle range of F hardness and the upper range of P hardness


Physical

 

Extended Length

220cm/300cm

In the standard configuration, the max depth that can be probed is 220cm. A 300cm option is also available. For depths greater than 300cm, custom solutions are available.

Collapsed Length

43cm

 

Weight

385g (220cm)

475g (300cm)

The scope will collapse and fold up to this length similarly to an avalanche rescue probe
