couldn't you just set your edge 520 to one data field and set it to power?

2019 T-Rex Tri Series

Wahoo bolt. Bought for same reason. Can zoom in and out with side buttons up and down.

When you zoom in you lose fields but the what shows is bigger. Still records them though.

Wahoo Elemnt can show numbers in a huge format. The Bolt as well but display is smaller so the numbers are as well.
I recently also acquired an Edge 530 which is ok as well for me but it doesn’t have the ‘zoom’ function. Also on the Edge 530, the BBS power field is displayed in really small numbers, no matter the display setting on the Garmin and is simply unreadable for lots of people...

Super, thx

Yup. Spot on as I said.

Only reason I got wahoo was this feature. Now though, I wouldn’t trade wahoo.

I have my G 520 set to display Power, Cadence and Speed. The numbers are pretty big, if you can't see them you might have a vision problem or your head is way too high!

Vision problem, yes.

Glad the Garmin works for you.

On a Garmin device you could solve this by setting up different pages and scroll through them while we riding.
Overall, the Wahoo device usage and setup is the easiest and most user-friendly.
Garmin probably has more features but which device is best for you is really a personal preference.
I like both but if I had to recommend one to a now tech savvy person, I would recommend the Wahoo for sure.
If it were for myself I don't think I would prefer one over the other.
One thing I do not like with the Wahoo computers is that there is no sleep mode. When they power off, they do so completely and you have to reselect a route if you want to ride one. Max auto power off delay is 2h though which is long enough for most situations.
