Comparing Data screens Garmin -> Wahoo

I’ve been debating trying out an Element Bolt or Roam, I like the idea of something a little lighter, with easily accessible buttons, what’s always put me off is just how much data I can squeeze on my 1040.

My two main sceeens are;

Map, gears, wind, speed, avg power, hr, distance, cadence and time

Elapsed, gears, temp, wind, distance to destination, speed&average, hr&average, power&average&normalised, distance and cadence.

I know I’m not going to get quite as much on a bolt for example, but I’m wondering how close I can get?

What’s the max field count on a page? Are there fields or app that combine a data point and its average in one field? How many fields can I show with a map?

Iirc the maximum number of fields on the map screen is 5 or 6 and 9 or 11 on other screens (don’t have my roam here) but you can easily add screens and scroll through them with the press of a button

For the Wahoo Elemnt (not sure if Roam and Bolt are the same, I think they are):

The limits for non-map, non-elevation screens are 11 data fields
On the map screen you can have up to 6 data fields
On the elevation screen you can have 7
You can have several custom screens with up to 11 data fields

You also can’t have the current speed/HR/power shown in the same data fields as average, but you can have a little arrow indicating if the current value is above or below average.

I don’t know where you’re getting wind data from, but Wahoo doesn’t have that and doesn’t allow third party data fields. So you you’ll lose that.

I’m also really curious how accurate and useful that wind data really is?

Presumably your don’t have a wind sensor, rather the data is being pulled from some weather source, which is going to give either a predicted or delayed actual reading.

I just take a peak at the weather app before getting dressed to know generally what to expect. In the real world the wind speed and direction changes a lot, especially with foliage, buildings, hills etc blocking it sometimes.


Uses weather data, you can pick a few sources - I used a paid one, I forget the name, that seems pretty good.

It updates in real time as I’m riding, both in compass and windspeed. It’s usually a very good indication where I live (flat SE England), though it can often be off by a few degrees as you’ve alluded to, but I like having the information but I think it’s mostly a confirmation thing rather than anything useful beyond encouraging me to push for segment when I’ve got a strong tailwind :smiley:

There are places where it’s useless, though. Mallorca is one of them, I don’t know if it’s because Mallorca gets a few different winds, whether the reporting/forecasting is bad or what.

Plus one more physical “field”, left side LED:

  • HR zone
  • power zone
  • speed
  • approaching car approximity (with radar only, ofc)

It’s surprisingly handy. With the map zoomed out enough + WindField you can quickly evaluate what wind you’ll be dealing with up the road - head/cross/tail/etc.

Accuracy depends where you are. Where I am it’s relatively flat with a lot of open space, so it’s good. Over in the Adelaide hills in January it wasn’t as useful.

Was that because the hills interfered with the accuracy of your location or because they effectively blocked / manipulated the wind, depending on the profile around you?

At best it’ll update once every 5 mins. Still pretty good enough though.

I didn’t look too much into it. I assume the weather stations were too far away, possibly in the city/airport in Adelaide (almost dead flat).
