Golmar has traditionally offered several options within their Tekna range of monitors; Mono/Colour, Uno/Plus and Digital/2 wire/5wire.
Some might say too many options. This range has now been reduced.
As for many other brands on the market, for commercial reasons, mono options are no longer viable.
It has now become viable to replace the UNO (the basic) range of monitors with a monitor offering all the additional features of the PLUS range and more!
The new Tekna Plus SE will replace both the UNO and PLUS range of monitors.
These new monitors are fully compatible with all Plus and Uno monitors already installed.
