The Troll Master Depth Calculator - FREE is a comprehensive app for fishing enthusiasts, available on the Android platform. It is an ideal tool for calculating depth while trolling and creating dive charts. The app lets you select your line, your lure, a diver or trolling weights, and then combine them however you want. By changing line length, speed, weight, leader length, rod height, lures, and other factors, you can easily and quickly see the effect on your trolling depth.

The app is updated regularly with new lures and tackle, making it an excellent choice for anyone who fishes in saltwater, freshwater, or anywhere in between. It has many features for walleye, trout, salmon, striped bass, red drum, tuna, wahoo, and pretty much any other species you might troll for. The app uses physics-based calculations to determine the trolling depth of your lure with precision based on your inputs. The calculations have been verified via on-the-water testing.
