The Varia RCT715 is Garmin’s top-of-the-line 3-in-1 cycling safety device, combining a rear radar, rear-facing camera, and taillight in a single seatpost-mounted unit. It’s been on the market since 2022 as the flagship of Garmin’s Varia radar lineup (alongside the simpler RTL515 and radar-only RVR315).<\/p>\n
Measures about 106.5 x 42 x 32mm and weighs ~147g \u2014 nearly double the weight of the radar\/light-only RTL515, due to the camera. It uses a more robust locking mount (not compatible with older Varia mounts) with rubber shims for round, aero, or D-shaped seatposts. Rated IPX7 water resistant.<\/p>\n
USB-C charging, ships with a 16GB microSD card (supports up to 512GB, though the companion app is limited to handling 128GB of footage). Connects via ANT+ and Bluetooth to Garmin Edge computers, compatible watches, and other head units (Wahoo, Hammerhead); works with 97 Garmin devices total.<\/p>\n
Has its own onboard accelerometer-based crash detection that locks and saves footage automatically \u2014 though notably, this doesn’t alert anyone (unlike a paired Garmin Edge or watch’s own incident detection).<\/p>\n
Varies significantly by mode \u2014 up to 4 hours with camera recording at 1080p, up to 6 hours in solid light mode with camera off, up to 10 hours in day flash with camera disabled, and up to 6 months in standby.<\/p>\n","protected":false},"excerpt":{"rendered":"
