Summary: The Black Diamond Recon LT was a promising avalanche transceiver that was available for less than two years. Initial reports implied it was as capable as the Recon BT at a fraction of the size. Unfortunately, it was recalled because "in rare and unlikely circumstances" it could "enter search mode due to interference from other beacons." The recall was for a firmware update, but Black Diamond also stopped selling the LT shortly thereafter. I contacted Black Diamond and they said it was fine to keep using Recon LT transceivers after they are updated, but they confirmed the transceiver has been discontinued.
The rating of this transceiver is tentative, at best. I was never able to test a Recon LT. The score shown here assumes that the Recon LT has similar functionality to the Recon BT and takes into consideration that the transceiver was discontinued. The score doesn't include extra value for its small size and lightweight.
