Trouthooker PRO Stillwater Trolling Depth Calculator

Trouthooker PRO Stillwater is a precision trolling depth calculator built for stillwater trout anglers who want to stop guessing where their lure or fly is running. The app lets an angler enter a real fishing setup, compare depth behaviour, and make better on-the-water decisions before the next pass across the lake.

Built for practical stillwater depth control

The calculator is designed around the variables that matter when trolling: line type, line out, trolling speed, leader length, sink tips, added weight, and lure or fly profile. It gives an instant estimated running depth with a confidence range, then displays a visual depth trajectory so the angler can see how depth changes as more line is let out.

It supports conventional and fly fishing setups, including mono, fluorocarbon, braid, lead core, copper wire, full-sink fly lines, sink tips, and polyleaders. Anglers can save favourite setups as presets, compare fly line sink-rate behaviour in the depth curve library, and use target depth mode to work backward from the water column they want to fish.

The dark, high-contrast interface is built for lake conditions, bright glare, and quick adjustments from a boat. Imperial and metric units are included, and the app is designed to be useful on the water where cell service is unreliable. Depth estimates are approximations and should be verified with electronics or on-water observation whenever possible.
