Fairhaven Micro Vario

The Fairhaven micro vario is designed for paragliding, hang gliding and paramotor pilots who want to find thermals and other rising air to maximise their flight times, while using the minimum of equipment. At only 15 grams and just over one inch square, it’s the world’s lightest, smallest and toughest little vario. It uses the latest, most sensitive digital air pressure sensors which are incredibly small and immune to temperature change and radio interference.


Micro Vario Key Fetaures:

  • Great tone range, sensitivity and damping for optimal lift and sink indication.
  • Easily switch between sensitivity settings – no multiple button sequences.
  • Supplied with Velcro riser/harness fixing and backup strap.
  • USB  charging  from  PC  or  car – lasts up to 7 days flying!

Micro Vario Product Information

Audio tones

Tones are typical for an audio vario with a modulated “pip-pip” that increases in rate to indicate lift and a lower frequency “buzz-buzz” for sink. Frequency and interrupt rate vary according to rate of climb/descent. Averaging is typical, at just over one second and tones are loud with the bleeper operating at 8 volts!

Headphone/external bleeper socket

As well as having an internal audio sounder or “bleeper” the vario has a socket for an external bleeper that can be worn under the helmet, even with open ear types. This is particularly useful to paramotor fliers who use thermals, and even if you fly with a full sized alti-vario, the Fairhaven mini vario will be easier to hear and is just as sensitive.

As well as our extension bleeper any type of stereo earbuds can be used, or it can be connected to an intercom for tandem or sailplane gliding, to your paramotor headset auxiliary input or as an aid if you have impaired hearing.


The mini vario can be mounted on the back of your helmet or inside the helmet’s collar, to avoiding line snags. You can also fit it to your flying suit or harness, or it can be panel mounted and we supply 5 adhesive Velcro pads that will stick to most surfaces and can be sewn onto clothing.

It’s tiny size makes it ideally suited to fix on your risers, right next to your ear! So we also supply a Velcro wrap for riser mounting and there’s a cord provided as a backup, although the Velcro is surprisingly strong!


The battery is a 100mA re-chargeable Lithium Polymer type that is automatically re-charged when the vario is plugged in to any USB 5 volt supply, such as a computer, phone charger, satnav lead or solar charger and we include a neat little charger that plugs into your car’s cigarette lighter socket.

The vario lights up when charging and a full charge of one hour will supply the vario for up to 7 days of typical use, without having to rely on the sun shining and there are no expensive batteries to buy!


Next to the headphone jack is a sensitivity switch. 3 settings are provided to suit most requirements while being very easy to change. Just slide the recessed switch as required:
