Ortovox S1+ Avalanche Transceiver Review

The Ortovox S1+ is the successor to the Ortovox S1. This page explains the differences between the S1 and the S1+. Read the Ortovox S1 review to learn about the core features in both avalanche transceivers.

All Ortovox S1+ beacons have been voluntarily recalled. If you own an S1+, you should stop using it immediately. Learn more here.

Enhancements to the Ortovox S1+:

• The S1+ uses Ortovox's " orientation-based antenna" technology that selects the transmission antenna based on the device's physical orientation. This resulted in a slightly longer "y-axis" antenna which should, theoretically, allow for a slightly wider search strip width than the basic S1.
• The number of batteries was reduced from 3 to 2. Ortovox tells me that the removal of the battery resulted in a longer reception range (due to reduced interference).
• The device has a rubberized coating that makes it easier to hold with gloves.
• The S1+ uses an accelerometer, rather than a compass, to sense subtle changes in direction while searching.
• The S1+ does not include a thermometer or navigation compass.
• The S1+ cannot be switched to analog.
• The menus have been redesigned to have fewer icons and be more intuitive. (You can upgrade your S1 to simplify the menus, but it still won't be an S1+.)
• The S1+ includes a new "deep burial" mode . (You can upgrade your S1 to have this feature.)
• Ortovox began installing a RECCO reflector in the S1+ in October 2013. (Read the details.)

The S1+ began shipping in Late-2011.
