LocusMap app on Garmin device

Good evening everyone,

I tested the app on my Tactix Delta to connect my watch to my S23Ultra, and now I have the main navigation data on the Tactix. However, I would like a larger screen and I'm considering purchasing an older device like the Oregon.

Has anyone tested it with this type of device, and does it work as well as on my watch?

Is the display full screen and will it be more visible than on my Tactix?

Thanks for your feedback...
