Garmin varia RTL510

Crutchfield customer from Corte Madera, CA on 4/30/2019

Verified customer (What's this?)
Verified employee purchase (What's this?)

When I first heard of the Varia RTL510, my first thought was, this is a gimmicky gadget. Now that I own one I can clearly say this is a must have item. It is fabulous. It enables me to know if a car is approaching in order to monitor my surroundings. Further, Once you get used to their scale, meaning where the circle is on the scale which represents the approaching vehicle, it gives you an idea how far away that car is, (it picks up an approaching motorcycle also). It's almost indispensable. I highly recommend, in the name of safety, A must have for every cycler. Now for the Cons. First, it is pricey, however worth it in the name of extra safety. which is priceless. But, Hey Garmin you could do a little better with price. Further, Garmin supplies this with a universal clamp that uses large rubber bands. This I found is unacceptable. I know Garmin had to invent something universal due to all the different shape seat post out there. However, unlike my Edge which sits on my handlebar and I constantly see, if it fell off I'd notice. The Varia is behind me mounted with Rubber Bands. For such an expensive product I would have liked to see something in terms of mount, a little more assuring. Battery life seems it could be a little better for Edge when using it with Varia. However, due to the usefulness of this product I have no complaints having to more frequently charge The batteries. Yes I highly recommended, and it is compatible with a long list of Garmin products.

Pros: Usefulness

Cons: Universal Mount, Battery

Helps Cover Your Six

Shayne from Louisville, KY on 10/10/2018

Verified customer (What's this?)
Verified employee purchase (What's this?)

Superior upgrade from its predecessor, the RTL500, in both looks and performance. Looks more like a typical bicycle light. The light is bright and powerful. The radar is very effective and especially user friendly when paired with a Garmin bicycle computer. Seems to be very solid and well built. I bought the seat post mount because I hate to rely on rubber bands to secure an expensive item. I wish they would add a lanyard as they have on the computers for some added security if it were to detach from the mount.

Pros: Solidly built, bright, and effective radar.

Cons: Needs a Lanyard. Should be able to see battery level on Garmin Edge and/or battery level indicator on the unit, and auto on/off would be handy.

The bike gadget you need

Crutchfield customer from St Petersburg, FL on 7/22/2018

This is the bike gadget you didn't know you needed. It is so cool (and safe) to know that a car is coming up behind you while riding. This device beeps and shows a visual indication of rear approaching vehicles. As an added bonus we were able to pair it to two riders Garmin 520 head units so we both got notification of approaching vehicles.

Pros: Safety Great notification of approaching cars

Cons: Expensive

Features

Overview: The Garmin Varia RTL510 Radar Tail Light warns you of vehicles approaching from behind, while making you more visible to oncoming motorists. Getting hit from behind is the leading cause (40%) of cycling fatalities in the U.S. (according to a study by the League of American Bicyclists). Varia Rearview Bike Radar helps protect you by giving you an extra set of eyes watching behind you. The Varia RTL510 radar tail light requires the optional Varia RDU radar display unit, the Garmin Edge 1030, or other compatible Garmin device (all sold separately).

Note: This RTL510 Radar Tail Light is also available in a bundle, along with the Varia RDU Radar Display Unit.

Varia Smart Bike Lights: The Varia line of cycling awareness products includes smart tail lights, smart head lights, and dedicated display units. The RTL510 radar tail light can detect vehicles approaching behind your bike, and wirelessly display the relative speed of approach and threat level on the dedicated display or on a compatible Garmin Edge cycling computer. The bright RTL510 tail light also notifies the approaching vehicle of your presence.

RTL510: The RTL510 radar tail light mounts high on the seat post on your bicycle. The bright LED light is visible up to a mile away in daylight, and is visible within a 220-degree range. The RTL510 uses low power radar to detect up to eight vehicles approaching from the rear. It then alerts you through a dedicated radar display unit or a compatible Garmin Edge bike computer (such as the Edge 1030). The radar detects approaching vehicles up to 153 yards (140 meters) away, at speeds between 6 and 99 mph. The radar beam width is 40°, to provide coverage for typical bends in the road. The tail light features a large, bright LED with three modes: solid (20 lumens), night flash (29 lumens), and day flash (65 lumens). The RTL510 uses 2.4GHz ANT+ technology and wirelessly links to the RDU or Edge unit. Dimensions of the RTL510 are: 1.561"W x 3.892"H x 0.908"D. It weighs 2.5 ounces.

Garmin Edge Compatibility: The RTL510 is compatible with the Garmin Edge 1030. The unit will display radar information and alerts from the RTL along the edge of the display. It also provides audible tone alerts when vehicles are detected (if tones are enabled in the settings menu). As with the RDU, the threat level LED and vehicle position LEDs have similar functionality.

Note: Other compatible Garmin units include Edge 1000, 820, 520, 130, Forerunner 935, fēnix 5 series, and vívoactive 3 watches.

Rechargeable Batteries: The Varia RTL510 is powered by a built-in rechargeable Lithium-ion battery. The RTL510's battery life is approximately 6 hours in solid or night flash mode, and up to 15 hours in day flash mode. Using the supplied USB cable, the battery charges in approximately 3 hours via USB plugged into an AC power source, or 5 hours plugged into a computer.

Mounting: The RTL510 is equipped with a "quarter-turn" mount that attaches the light to the seat post.

Water Rating: The RTL510 has an IPX7 water rating, making it suitable for use in rain or snow. It can withstand incidental exposure to water, but is not suitable for immersion.
