VSpeak-Vario (pro) for Spektrum
The "pro" version of the Vspeak-Vario has a higher sensitivity than the standard version.
The properties of the used Swiss precision pressure sensor in the "pro" version which is manufactured in modern MEMS technology allows a faster response and results in less noise.
Furthermore the "pro" version has been equipped with an acceleration sensor which has an extended measurement range of +/-24g in all three axes.
Single cell monitoring and logging of measured values carried out like standard Vario.
Note to spectrum receivers AR7350 / AR 9350:
This receiver series is unsuitable for the transmitter-side Vario tone production, compared with the TM1000 the vario is very sluggish and therefore unsuitable for ambitious pilots.
This also applies to the use of the spectrum own Vario SPMA9589.
If only components of VSpeak used for vario signal, so VSpeak speech module in the transmitter and the VSpeak Vario on the receiver side, then there is no difference to hear - whether the vario is connected to a AR7350 / AR9350 or the TM1000.
Externally the VSpeak-Vario "pro" can be distinguished from the standard version by the logo "pro" on the bottom of the vario
