Display sun glare is my number one issue with the eTRAC.
One of those non-glare screen films helps a 'little', emphasis 'little'.
Glare is only part of the problem, the bigger problem IMO is a low contrast display with a darkish gray background and black graphics which direct sunlight will wash out.
Add sunglasses to the mix and its impossible to see display readouts under direct sunlight conditions.
I have a much less problem viewing the display on my ATPro under direct sunlight. But then again the ATPro has a high contrast display with a whitish background and black graphics and it costs less than half the price of the eTRAC.
I either shade the display with my hand which is a PITA because its usually holding my digging tool or like nge, just sweep in a direction where there's no glare.
Gonna experiment by jury rigging some kind of removable shade over the display to see if that helps. If anyone here has done that, i'd sure like to see a picture of it.
