Too bad. Fishfinder might be useful for finding fish... if you have a possibility to borrow it for a few days, you may try its possibilities.
I'll target the weed bed to the north of dad's pond, assuming there has been a late bloom of weeds (dad says he can still see some from his dock).
I might be repetitive but I doubt that it's smart idea to search for pikes near weeds in winter. There might be some but not as much as in summer. It's because of rotting weeds - fish don't like such circumstances. They try to move deeper.
