Hunting for Shed Antlers?

Hello! I've looked through this, the travel sub, and the general Norway sub but haven't seen anything yet. Anyone have advice on best time of year to hunt for antler sheds in the Tromso area? I'm aware of when the deer themselves shed their antlers, but is the best answer to just wait until summer snowmelt? Or is this just an exercise in folly to begin with? Thank you for any advice (and please consider handling this silly fool with care, I don't generally deal with feet upon feet of snow where I'm from in Virginia USA when hunting for sheds).
