At a quick glance they both have the same display size/resolution and similar battery life/basic performance.
The 73 floats and the Etrex doesn't (as far as I can see). Also I think the 73 has slightly better waypoint/track ability but I haven't studied what that means in reality for sibbing.
You may prefer the front buttons on the 73... even after 10yrs I sometimes forget which of the unmarked side buttons I need to press on my old Etrex. At least they have put some markings on the front Etrex 10 as to what the buttons do but still less clear to use at sea than the straightforward 73 model.
I checked the reviews just now on Amazon and a couple saying the screen etc not as good as the 72.
Just checked and the newer model is indeed narrower = daft?!
TBH reluctant to buy in some respects as my 72 failed on water ingress and it's only been splashed not dunked but the legibility and simple features were good. As I say all I really need is a clear ktph read out and record of distance/time plus the odd use of the compass and distance/time to next waypoint which the 72 provided well. Battery life was OK but 73 promises 18 hrs.
Might just look out for another lightly used 72...
