General 147 6ft Fraction & Digital Fractional Caliper - Fraction, Inch

In this review the General 147 6' Fraction & Digital Fractional Caliper is evaluated for workshop and hobby use, and its single biggest reason to buy is the combination of fractional display and high resolution that removes guesswork when converting measurements. The caliper is aimed at users who need quick, accurate fractional, decimal and metric readings in a compact 6' tool, and the review focuses on build, readout clarity and practical measurement modes rather than marketing claims.

Key Features

• 3 Mode Digital Display: Instantly converts between inches, fractions and millimeters so users can read measurements in the system required for a job without manual conversion.
• High Accuracy: Guaranteed accuracy to 0.001' and +/- 0.02mm provides confidence when measuring fine tolerances for machining, woodworking or inspection tasks.
• Heavy-duty Stainless Steel Construction: The rugged body resists wear and keeps jaw alignment stable for repeatable inside, outside, step and depth measurements.
• Convenient Auto-off Feature: Automatic shutoff preserves battery life for long periods of intermittent shop use and prevents unexpected dead batteries on the job.
• Compact 6' Range: The 6' capacity is a practical size for most bench and field tasks while staying portable and easy to store.

Who It's For

The caliper is best for woodworkers, metalworkers, hobbyists and technicians who regularly switch between imperial fractions, decimal inches and metric units and want a single tool that handles all three. Its fractional display and 1/64' resolution make it especially useful for those working from plans or parts specified in fractions.

It is less suitable for users who need longer measuring ranges beyond 6' or who require specialized calibration certificates; those users should consider larger bench or gauge tools designed for higher-capacity measurement work.

Pros & Cons

Pros

• Three display modes eliminate manual conversion and speed up layout and inspection tasks.
• Strong stainless steel construction maintains accuracy over regular shop use.
• High resolution and stated accuracy support fine measurement needs down to 0.0005' resolution in decimal mode.
• The included foam padded plastic case protects the caliper in storage and transport.

Cons

• Limited to a 6' measuring range, so it will not replace larger calipers for big workpieces.
• The review notes no mention of an IP rating, so users in wet or very dusty environments should take care.
