Best Wi-Fi Signal Finder Yet

Chrysalis previews their WiFi Seeker, a keychain sized device for instant Wi-Fi signal finding: Chrysalis sent me a demo unit of its just-unveiled WiFi Seeker, which they designed to differentiate 80211b/g networks from other devices. Two previous Wi-Fi signal finders fell short in ways the Seeker does not.

The Kensington WiFi Finder is relatively large (credit card sized) and scans before displaying the results instead of a constant active scan—but it can tell Wi-Fi from junk.
WFS-1 from SMart ID is much cooler offering a no-industrial-design-intended box with instant scanning—but which "hears" all 2.4 GHz signals the same.
Push the button on the WiFi Seeker and it scans briefly, often under a second, before displaying a signal strength in zero to four LEDs. Keep the button held down and it’s a Wi-Fi dowser, allowing you to move around and see immediate response to different signal strengths. It’s more directionally sensitive than the WFS-1.
Chrysalis will sell the device starting in June for $29.95. Earlier, PC Tel has said they would make the device available to their customers, so one presumes that Chrysalis can sell custom branded versions of the device.
