You might call the Davis Instruments Vantage Pro2 the “granddaddy” of personal weather stations. This model has been around for the better part of two decades: I actually owned a first-generation Vantage Pro in the mid-2000s. It was the best weather station I ever owned and was worth every penny of the $500 I spent on it at the time. Inflation over the past 20 years has made it more expensive, but it still is a great value for the accuracy it provides.
Why has the Vantage Pro2 withstood the test of time? It’s actually very simple: quality. This station is one the best you can get in that department. High-quality sensors provide market-leading accuracy, corners aren’t cut in construction. It’s truly pro-grade.
- Self-contained, easy-to-install system includes sensor suite and WeatherLink Live.
- Stream live weather data over Wi-Fi to the WeatherLink Cloud: see updates on your smartphone as they happen when the phone and WeatherLink Live are on the same local network.
- Accurate, reliable weather monitoring with real-time data updates every 2.5 seconds.

But over the past few years, the whole setup began to feel dated. The Vantage Pro2 has the same connectivity issues as the Vantage Vue. Other weather station manufacturers are adopting new technologies. The Ambient Weather WS-5000 uses a sonic anemometer; the WeatherFlow Tempest features a built-in lightning detector.
Davis is finally starting to address the shortcomings of its lineup. The new WeatherLink Live makes connecting the Vantage Pro2 to the Internet so much easier. Davis recently made a sonic anemometer an optional upgrade. But is this enough to keep it on top?

What is the difference between the Pro2 and the Pro2 Plus?
The Vantage Pro2 Plus comes standard with the UV and solar radiation sensors. If you buy the Pro2, and later want these sensors, you’ll have to purchase them seperately, which is a lot more expensive. Other than that, they are exactly the same. Most weather enthusiasts will be well served by the standard Pro2 model.
What is the difference between the Vantage Vue and Pro2?
The biggest difference is the sensor suite. The Vantage Vue uses a integrated sensor suite, which is how most weather station manufacturers do. The Vantage Pro2 has a seperate anemometer, which allows you to place it at the correct height. In theory, this will give you more accurate readings. The Vantage Pro2 allows for expandability without the WeatherLink Live base unit.
Is the Davis sonic anemometer worth it?
Sonic anemometers are becoming more popular in home weather stations. They do have a few distinct advantages, including no moving parts, and much better sensitivity and accuracy. However, they also have a limit of 89.5mph. The standard Vantage Pro2 anemometer has withstood wind gusts up to 199mph! Most of us will never see winds higher than 90mph in our lives, so unless you live on the coast, you should be fine.
Setting up the Vantage Pro2
The Vantage Pro2 is a feature-packed station, so there are a lot of parts to put together. And installation time will vary depending on which package you buy: this package here should take about 30-45 minutes, although you might need an hour or more.
Install the sensor suite first, as you’ll need it reporting before setting up your WeatherLink Live base unit. Davis’s directions are pretty easy to follow for both, so we doubt you’ll have any issues. If you need some help in placing your weather station, see our siting and mounting guide.
After both the console and sensor suite is set up, you can set up the rest of your sensors, which are fairly easy to both mount and add to the weather station installation.
Good luck finding an equal in terms of accuracy — there isn’t one. The Vantage Pro2 is the market leader here. Most of the sensors in the Vantage Pro2 are better versions of what you find in the Vantage Vue — and many are replaceable. An innovative sensor suite is the star of the show here.
There are some differences from model to model in terms of sensor shielding. In higher-end models, the radiation shielding around the temperature and humidity sensor is “fan aspirated.”
Fan aspiration improves the performance of the shielding. While the larger amount of space around the temperature/humidity sensor should allow for better airflow than the Vantage Vue’s compact design, some heat buildup still occurs. A fan inside the shielding helps to move air around and keep this from occurring.
The Vantage Pro2 also features a large cone called the “Aerocone” to improve the rain gauge’s accuracy. Davis says that the cone’s shape prevents turbulence around the mouth of the gauge, which can prevent rain from making it into the gauge itself.
With the Vantage Pro2, you now have the option between the traditional cup and vane anemometer and a new sonic anemometer. While you’ll get better precision wind readings with the sonic anemometer option, you’ll also pay a good deal more as well.
A Dated Display, But
We won’t sugar coat it — the Vantage Pro2 console is pretty dated. But it sure is chock full of information, with indoor and outdoor temperature and humidity, rainfall, wind speed and wind direction, moon phase, barometric pressure and barometric pressure trend, and a graph to view that and other trends all on the front screen. There even is a banner across the bottom which changes automatically to highlight information, such as a text version of its weather forecast (also displayed!) or important weather measurements.
We hear rumors that the company is working on a new console, but with WeatherLink Live out, we believe Davis is moving towards console-less stations, much like the WeatherFlow Tempest. But for now, you’ll have to deal with your real-time data on a console that looks like it’s out of the 1990s.
Davis Vantage Pro2 vs. Ambient Weather WS-5000
We are increasingly seeing comparisons between the WS-5000 and the Vantage Pro2. We think this is a fair comparison, as the WS-5000 is Ambient Weather’s top of the line model. However, we still feel the Vantage Pro2 has more accurate instrumentation overall. However, for smart homes, Davis weather stations just don’t cut it. If you have a smart home, you’ll need the WS-5000.
We sincerely hope that Davis Instruments is working on a solution to this. While their new WeatherLink Live base unit gives it more connectivity, it is still not enough.
Upgradability and expandability
While the WeatherLink Live does at least make the Vantage Vue slightly more expandable than it was before, you’ll still need to buy a Vantage Pro2 for most of Davis’ optional sensors.
Davis’ new AirLink air quality monitor is a solid addition and is one of the few on the market to measure PM1 as well as the standard PM2.5 and PM10 pollutants. If you’re frequently outdoors, the UV and solar radiation sensors are useful. There are also leaf and wetness sensors, great for gardeners.
The only negative is that these sensors can add up: they’re not cheap. But the same Davis weather station quality that you find in the Vantage Pro2 is found in the sensors — these also have great track records in long-term reliability.
Which Vantage Pro2 do I need?
Davis now has quite a few different package options available. To make it easier to choose, we’ve narrowed down the list to the best options that we’d recommend.
The addition of WeatherLink Live seriously upgrades the communication capabilities of the Vantage Pro2. Previously, you had to purchase an expensive (and outdated) ethernet dongle to connect your station to the Internet.
While real smart home connectivity other than an Alexa app is still missing, WeatherLink Live makes more sense. It appears that the newer sensors that Davis is releasing are built to be compatible with the WeatherLink Live directly, so options may grow with time on what you can do.
What we really like about the connectivity is the live updating within the app. It’s a nifty feature, and I’ll admit to watching it intently during some of our stormiest weather.
What’s nice is from what we’ve seen, it isn’t any more expensive than the old dongle, which didn’t have the functionality the WeatherLink Live has. Unfortunately, it’s also not any cheaper.
The Vantage Pro2 can’t be beat
The only thing that holds us back from giving the Vantage Pro2 five stars is its connectivity options. While it’s improved, it’s still behind everyone else. Otherwise, the Vantage Pro2 is in a class of its own.
Of course, the price of this weather station is a big deterrent. It doesn’t make much sense for a casual weather observer to buy the Vantage Pro2 — these users would be better served by a station like the Ambient Weather WS-2902C. But for serious weather enthusiasts looking for a solution with proven long-term reliability and accuracy that none can match, the Vantage Pro2 should be at the top of your list.
For those looking for a more budget-friendly high-end station, we’d recommend considering the Ambient Weather WS-5000. But do keep in mind that the accuracy — while very good — still doesn’t match what we see out of the Vantage Pro2 line.
