Hultafors Talmeters secret is that you can take a measurement and then mark it directly onto your workpiece, without even reading off the scale to verify the length. This will be your favorite way to measure. The talmeter has a calliper function that is handy to mark out round shapes. The extender is easy to extend and retract using the grip-friendly sliding carriage. We have the talmeter in diffrent lengths and spare parts.
