Rangefinder Lifecycle

[marfau23]

Is there a rule of thumb for when to replace rangefinders? I can’t imagine they’d go bad but has the accuracy really improved over the last decade to be worth shelling out a few hundred bucks for a new one? I’m not the biggest believer in the slope adjustment (think it’s more variable based on club and trajectory based on the individual’s fought characteristics than simple math) so I don’t feel the need to “upgrade” for that feature and can’t imagine things have gotten that much better. Any arguments to that?

The only reason I upgraded my rangefinder was to progress from a battery unit to a usb unit.
