Cruiser’s Crutch, English

Provides correct readings on 0 to 90% slopes for English BAF’s: 10, 20, 30 or 40, or for Metric BAF’s 2, 3, 4, 5, or 6. Clear, tough Lexan with 26” nickel-plated chain has four brass balls, one for each BAF. To use, determine slope to the nearest five percent. Hold the brass ball for the selected BAF under your eye and extend the Crutch away until chain is taut. Line up tree with appropriate slope percent line on the gauge. If the tree at dbh is wider than the line on the angle gauge being sighted across, tally the tree. Available in English or metric models.
