Regular price $49.90

Digital 3-in-1 Marking & Mortise Combination Gauge

Marking gauges are great for layout work in your shop because they're many times more accurate than thicker pencil lines. But the advantage of scribing doesn't end there; a scribed line pre-scores your wood, making final cuts with your hand or power tools more crisp and clean by eliminating unsightly tearout. But wait, there's more! When you use a scribed layout line you create a very fine registration point for starting your chisel, hand saw or power tool cut. You won't have the "which side of the pencil line should I start on" question that inevitably creeps into your head when working with a thicker pencil layout line.

With this digital 3-in-1 marking gauge you get all the benefits of a traditional scribing and layout tool with the obvious advantage of digital accuracy. The tool features a hardened marking pin for accurate scribe lines as well as a double pin setup for simultaneously marking both sides of a mortise. The hardened alloy marking pins come to a sharp point and score your material beautifully, even against the grain. Use the large square reference fence to set your scribe line in the exact location needed, then lock in place with the thumb screw. Attach the included third pin under the display to turn it into a digital divider for marking a circle or radius.

Features include:

  • Measuring range from 0" - 6"
  • Compass range from 0" - 8" radius
  • Divider range from 0" - 16" diameter
  • Accuracy within .001" (how's that for precision woodworking!)
  • Easy to read extra-large display
  • Displays in inch, metric and fractional 3-way readings
  • Humidity and dust resistant
  • Battery included

Frequently Asked Questions

What is the measuring range of the iGaging gauge?

The marking gauge has a measuring range of 0" to 6", with a compass range of 0" to 8" radius and a divider range of 0" to 16" diameter. Browse more gauges & setup tools.

How accurate is it?

It is accurate to within .001", giving you true precision-woodworking layout in a digital marking gauge.

What are the three functions of this gauge?

It works as a marking gauge, a mortise gauge, and a digital divider. A single hardened pin scribes lines, a double-pin setup marks both sides of a mortise, and the included third pin converts it into a divider.

Can it display metric and fractional measurements?

Yes. The extra-large display shows 3-way readings in inch, metric, and fractional formats, so you can match whatever system your plans use.

How do I mark both sides of a mortise?

The tool has a double-pin setup that scribes both walls of a mortise at the same time, ensuring consistent, parallel layout lines. See more marking tools.

Why use a scribed line instead of a pencil line?

A scribed line is far finer than a pencil line, pre-scores the wood to reduce tearout, and creates an exact registration point for starting a chisel, hand saw, or power tool, removing the guesswork of which side of a pencil line to cut on.

Does the gauge come with a battery?

Yes, a battery is included, so the digital display is ready to use out of the box.

Will the pins scribe cleanly across the grain?

Yes. The hardened alloy marking pins come to a sharp point and score the material beautifully, even against the grain.

Is it durable enough for shop conditions?

It is humidity and dust resistant, so it holds up in a working shop environment. Use the large square reference fence and thumb screw to lock your scribe line precisely.

Can I use it to lay out circles or arcs?

Yes. Attach the included third pin under the display to turn it into a digital divider for marking a circle or radius, with a compass range up to 8" radius. Pair it with other measuring & layout tools.
