What People Say
Synthesized from 16 reviews · 100% verified purchases.
Consider the Tajima's large size and sharp point if you need one-handed use with a tape; for the Johnson, you may need to enlarge the string hole for thicker cord. Neither includes string, so have some ready.
- Magnetic strength and utility
- Durable and long-lasting build
- Precise and accurate plumbing
- Effective in windy conditions due to weight
- Sharp point and large size hinder one-handed use with tape
