PERFECT VISION BIRDOG USB PLUS.
Please be so kind and let me know where i can download upgrade for this sat-meter?
Its possible updates may not be available.
This is a very interesting post on one of the Birddog distributors website:
As of 10/1/20, we unfortunately no longer support the Birdog Satellite Signal Meters as it got very difficult to get replacement batteries and other parts for them.
AND
Birdog Signal Meter Alternatives
We actually loved the Birdog Signal Meters in it’s day, but eventually
battery issues and hard-to-find updates made us invest into another solution – the XR-3 Signal Meters & Modules.
If the distributor cant get updates the average punter has no chance.
The birddog website no longer has any reference to satellite meters so they have dropped support for them.
