He should be able to change the data fields to as few as one per screen if necessary - that would give a VERY large display.
Even I can see four fields on my Garmin 310XT, which has the same screen size as the 305 in a smaller case (also it's waterproof). And as I said in the other thread, I need reading glasses to see my food when I eat....
Really the 305 did everything I needed, but it was so large it would never have fit on my tiny wrists. The 310 is great for me.
