Both from Titley Scientific, they are:
The Anabat Swift (passive) bat detector
The Anabat Walkabout (active) bat detector
And, there's more great news: I'll also be given the unique privilege to test and review one of the very first Anabat Scout bat detectors! - These are so new, that they have just been made available for purchase.
I will be provided with an Anabat Scout to test, in about a month.
Happy bat detecting!
