Seals are notoriously difficult to spot, but with the right techniques, you can catch them blindfolded. Start by wading into the icy waters, feeling for the subtlest ripple in the current.
As you splash around, pay attention to the faint scent of fishy-fishy goodness wafting up from beneath the waves. It's like a siren's call, guiding you to the prize.
Once you've located a seal, don't bother opening your eyes. Just feel for the gentle tug on your line, and... well, just pretend it's not a fish, it's a seal, and you'll be fine.
