Rare opportunities of catching quality fish like this 86cm Mulwala Cod (Three big Cod sighted in as many outings, unfortunately spooked the other two) after sighting them first can only be done with good quality polarized sunglasses to cut the glare and see deep into the water. I have fished Lake Mulwala for years and before these sightings I have never seen a free swimming Cod, I have never worn Tonic Sunglasses before either!!
