Every transceiver checked. Every time.
Automated verification for trailheads, gates, and patrol operations.
Detects transmitting avalanche transceivers as people pass, confirms them with audible and visual alerts, and logs every event. Runs on 12 V or solar, in weather.

Built for the places people forget to check
A transceiver check works best where it happens without anyone having to remember it. The DTS system is designed to sit at the point of entry and do that job unattended, season after season:
- Trailheads and backcountry gates — confirm a signal before anyone passes
- Ski patrol shacks and dispatch — verify equipment at the start of a shift
- Alpine huts and yurts — off-grid checks on solar power
- Avalanche education programs — give students immediate feedback
- Land managers and agencies — usage data for safety-infrastructure reporting
A complete system, in three parts
Deploy the checker on its own where power is available, or add solar and signage for a self-contained installation anywhere.
DTS Transceiver Checker
The detection unit. IP66-rated, powered by a BCA DTS Tracker, with event logging, relay control for gates and external devices, and over-the-air firmware updates.
Solar Power System
12V SLA battery, MPPT charge controller, and cabling in a waterproof enclosure. Wired and ready for a 50W+ panel you supply.
Custom Signage
A 36-inch printed sign that tells travelers what the checker is doing and what to expect before they pass it.
What it does in the field
- Detects multiple transceivers and reports how many are present
- Logs every event — up to 50,000 timestamped entries, downloadable as JSON
- Controls external devices through an onboard relay — gates, lights, horns
- Runs three power profiles — shore, normal, and low power for solar and remote sites
- Configures over Wi-Fi from its own self-hosted page — no internet required
- Updates over the air from a browser
- Detects Bluetooth devices in addition to transceiver signals
What a checker is — and what it isn’t
A transceiver checker confirms that a transmitting beacon was detected as someone passed. That is genuinely useful: it catches the beacon left off, the one still in the pack, the one with dead batteries. It is not a substitute for training, judgment, current forecasts, or a partner who knows how to run a search.
We build these because a signal check at the gate is one more chance to catch a mistake before it matters. It is not the last line of defense — you are.
