MAGNET Field Mobile also offers instant ability to securely login to your private Company Account within the MAGNET system to exchange files while standing at active projects sites.

Ratings and reviews

Great job changing UI without any notice. Came to project site and lo and behold completely new app and connot connect to LN100 because all of a sudden app asks for some license number... Thank you Topcon for "wonderful" strategy in app development. It's not YouTube or Twitch for you. People use it to do business and when I'm pressed by schedule to do 250x points and cannot use my tool because you wanted to be cool - this is not cool at all.

App will not open "MAGNET Construct keeps stopping" error pops up every time I try to open the app. All permissions were granted. Am I missing a requirement or prerequisite? Im using a Samsung Galaxy S7. Please help.

Take care buying this, unless you know you have good support. There does not seem to be a help system and Topcon provide nothing via their new website. You might struggle even to get started.
