This is an optional software update for the Nokta Makro Simplex+. Do not upgrade before reading this!

Firmware version 2.76 and 2.77 introduced a new search mode, Park 1, which increased the search depth. Users may experience jumpy Target ID’s, which is a normal result when identifying targets at extreme depth and under certain conditions. Some novice users may find these jumpy ID’s a bit confusing.

Firmware version 2.78 has been introduced in order to bring “stability” to the Target ID’s when hitting deep targets. In short, it does this by not displaying a Target ID for deep targets. Don’t worry, search depth is not affected!

If you don’t mind jumpy Target ID’s for deep targets, then we recommend you remain on Firmware v2.77. However, if you find jumpy target ID’s on deep targets to be a bit disconcerting, then update your Firmware to v2.78.

Another option is to upgrade the Firmware to v2.78 and give it a swing. If you prefer v2.78 then great, if you prefer v2.77 you can always downgrade back to v2.77.

This software update will NOT affect the overall depth and sensitivity of the Nokta Makro Simplex+.


Operating systems: Windows XP (with SP3), Vista, Windows 7, 8 or 10.

If you experience any issues opening the setup file, please disable all anti-virus programs on your PC.

The latest update includes all previous updates.
