Repairing you classis binos is like repairing or restoring a classic car... The parts are hard to find and expensive, it takes time, there is always more wrong than you think there is and you still have old, old technology when your done.

Your Trinovids are a classic... but they don't have the features a new pair of bino's will have... If it were me, I'd upgrade. Ovis_Chaser
