- ‘But more folks than you'd think toss hooks in that brown soup because there are some lunkers in the murky depths.’
- ‘Your Inuit guides will show you to Payne Bay Fjord, where low tides improve your chances of landing a lunker.’
- ‘Asp are primarily a shoal fish - or at least they are until they reach a real lunker size.’

- ‘We went ice fishing and Mrs. Rocket caught one of the all-time lunkers, only it turned out to be a long-lost fishing rod.’
- ‘Match the rod with the large arbor, disc drag, and precision handcrafting of Tibor's Tibor-Light Tailwater 5/6 designed by reel guru Ted Juracsik, and you'll turn fierce lunkers into Zen-garden goldfish.’
- ‘The 3.1-ounce 3200 balances well with the bantam-weight XP, yet houses a click drag strong enough to stop runaway lunkers cold.’
- ‘In addition to the familiar, lunkers engines, other large diesel aircraft engines were developed.’
- ‘This allows you to cover 10 to 12 miles of river, with the guide continually positioning the boat so both anglers get shots at lunkers holding in spots you just can't reach from the bank.’
- ‘The latest was a 14.28-pound fish from Falcon Reservoir along the Rio Grande, one of the state's older lakes and not high on most lunker hunters' favorites lists.’
