With the advent of electronic navigation in the twentieth century, magnetic compasses gradually lost ground to gyro compasses and global positioning systems. Iver C. Weilbach & Co. A/S never engaged in the production of electronic, navigational systems, which was mainly based on know-how developed in the military industry.

The company however continued to produce magnetic compasses until 2009-10 and employees of the company performed compass correction until the 1990s.

In the twenty-first century, new technological developments in shipping have again started to change the nature of Iver C. Weilbach & Co.'s business. The advent of electronic nautical charts and electronic publishing of maritime hand books has provided a new business opportunity for Iver C. Weilbach & Co. A/S, and the company has expanded its services in this field since 2005.

It now offers both printed and electronic nautical charts and hand books for onboard libraries and it is able to offer services and updates to the shipping companies on a 24-7 basis. A subsidiary in Singapore was set up in 2010.
