Why zygi

Network support

Mobile providers continuously upgrade their networks and will stop supporting 2G. The 3G version ensures continuity and international support. Additionally, the external booster antenna ensures reception even in areas where mobile phones are out of signal coverage.


Scale is very accurate in outdoor conditions and uses correction algorithm. Also with the second scale (optional) the result is ensured. You can experiment with different breed to see which one performs better in the area


Optionaly 5MPixel camera can be attached. It also supports a variety of analogue and digital peripherals to connect many sensors like your watering system, siren, alarm switches e.t.c.

I use the double scale version and I’m very satisfied of the performance and technical support.

In Australia we use it with the booster antenna and water level sensor in very distant areas.

It is a reliable scale with a very good accuracy. Configuration is very easy and the 3 batteries are enough. It has become an absolutely necessary tool in my beekeeping occupation.
