Laser Levels for Fencing: Laser, Stringline or Both?

A straight fence is a good example of why lasers and stringlines shouldn't be treated as rivals.

A laser can establish a useful level reference. A stringline gives you a physical line to work to for post alignment. On many fencing jobs, the best setup uses both.

For a normal garden fence

Start with the simplest method that works. A 100m stringline is excellent for keeping post centres visually aligned, while a compact line laser may help with shorter sheltered references.

For longer outdoor runs

As distance and daylight increase, a receiver-based rotary laser becomes more useful. The Grettz G60 offers a stated working range up to 400m with its receiver, so you can transfer a level datum without relying on seeing the red beam.

What about green?

Green can appear easier for the human eye to see than comparable red light, but bright daylight can wash out visible beams of either colour. For longer outdoor work, receiver compatibility matters more than marketing claims about colour.

Laser versus stringline

Use the laser for height and datum. Use the stringline for the physical post line. Use a tape for spacing. Each tool solves a different part of the job.

The bottom line

Don't buy a rotary simply because you're building a fence. For short garden runs, traditional setting-out tools may be enough. For longer or more demanding level transfer, a rotary and receiver earns its place.
