TrollDepth helps anglers estimate where their lure is running so they can spend less time guessing and more time fishing. Set up your trolling rig with the details that matter: leader distance, setback after weight, weight size, trolling speed, line type, line test, lure style, attractor, and target depth. TrollDepth calculates an estimated lure depth, gives a practical depth range, and tells you how much line to bring in or let out to get closer to your target. Built for salmon, trout, kokanee, walleye, and other trolling anglers, TrollDepth supports common trolling setups including snap weights, inline weights, keel weights, dodgers, flashers, inline trolls, cut plugs, lead core, sinking fly line, and more. Features: - Estimate trolling depth from your current rig - See a practical depth range, not just one perfect number - Set a target depth and get line adjustment guidance - Compare weights, speeds, line types, lures, and attractors - Use calibration to tune estimates from real sonar or field observations - Learn what each input means with built-in help - Save time when dialing in new water, new gear, or changing conditions TrollDepth is designed as a fishing aid, not a guarantee. Current, lure action, turns, line angle, rod position, knots, and real-world gear variation can all affect actual running depth. Use it as a practical starting point, then fine tune with your own sonar, strikes, and local conditions. Whether you are trolling reservoirs, lakes, bays, or big water, TrollDepth gives you a cleaner way to understand your spread and get your lure closer to the fish. We always improve based on your real feedback. A Tool For Anglers Designed By An Angler.
