Trolling Depth Calculator

The number one rule in catching fish is having a trolling depth calculator so you know you are getting the bait or lure to the fish’s depth. For conventional trollers without downriggers the trolling depth has been a big unknown. When the line slips beneath the surface it is like it has disappeared into a black hole and its depth is just a guess.

That has all changed with Ray’s Trolling Depth Gauge. This newly patented, easy to use, inexpensive device measures the depth of the lure or bait and an accurate depth is measured from the boat.

How The Trolling Depth Gauge Works

Ray’s Trolling Depth Calculator measures the depth when trolling with a conventional line using heavy or light weights, shallow diving, deep diving lures or diving planes, in freshwater or saltwater, in still water or flowing water, when windy or still. It remains accurate when trolling fast or slow and even when drifting with the wind or seas.
