Smart Trollers Know Exactly How deep Their Lures Run

The Smart Troll Probe is amazingly is literally the size of a fisherman's index finger. You can attach it directly to any line near your lure and it transmits Depth, Temperature and even Speed live data wireless through the water to your boat where it is displayed on any android device. You can also attach it to a down-rigger if you prefer.

You can attach multiple probes...up to six different Probes on six different lines at the same time (or multiple down-riggers if you prefer).

The Probes will transmit Depth, Temp and Speed data with over 300 feet of line out. Many captains report getting signals from the Probes with over 500 feet of line out.

The only way to truly know how deep your lures are is with "Smart Troll"

How deep are your lures…

Knowing exactly how deep your lures or baits are when trolling has always been a challenge for both novice and experienced fishermen (and women). Different techniques have been used to try and determine how deep a lure will run under specific conditions. Fishermen have trolled on a sloping sandy bottom until their lure drags bottom to make a log of what depth that occurs for each lure in their box, others have tried to make calculations based on line angle, and some have even used divers to determine lure depth and made charts and published books with the charts for others to use. The problem is…slight changes in conditions can affect a lure’s depth by several feet. Trolling slightly faster or slower, the wind pushing the boat sideways, waves rocking the boat (tugging back and forth on the lures), underwater currents, water temperature, line diameter, variations in the lures (even though they look identical) and other factors all combine in very complex ways to affect a lure’s trolling depth making it impossible to know just exactly how deep your lures are…until now.

Technology has arrived that will give every fishing person, whether a novice week-end fisher or experienced charter captain, the ability to know exactly how deep their lure, live bait or cut bait runs. The new system is called the “Smart Troll” system and it works by attaching a small Smart Troll Probe to your line. The Smart Troll Probe is ½ inch in diameter about four inches long and weighs less than 1 oz in the water. The Probe hangs from a short 175 lb test stainless steel leader with a loop for attaching it to the main line and a snap swivel for attaching it to the leader line. It is small and light enough so that it has little effect on lure action. It has no wires attached to it but its internal electronics are able to sense its depth, temperature and speed of the water at that depth. Every few seconds it sends a signal, through the water to a receiver on the boat. The signal is encoded with depth, temperature and speed information and is the user interface shows the depth of the Probe, the temperature of the water at that depth and the water's down-speed. Because the lure is just a few feet behind the Probe you know the exact depth that the lure is being trolled.

With Smart Troll when a change of conditions changes the lure’s depth, temperature or know within a few seconds because the Smart Troll receiver show the changes with live readings. Imagine the possibilities…

Scenario 1 (weeds)…I am trolling through water that I know is rich with fish and I see on the depth finder that I am marking fish 20 feet deep. But I pick up a weed which both contaminates the lure and changes the lure’s depth. Without Smart Troll I am unaware of the weed so I troll on through and wonder why I did not get a bite. But with the Smart Troll, I set the lure’s depth to 20 feet (where the fish are) but without any change in conditions I look at the Smart Troll display and see the lure raised to 10 feet….a sure sign that I picked up a weed or something. I reel in remove the weed set the lure back to 20 feet and in a few minutes I am shouting “Fish ON”.

Scenario 2 (Thermocline)…I know it is the time of year that the fish are hanging out near the thermocline I have heard that it is somewhere near 50 feet deep but exactly how do I find it. With Smart Troll all you have to do is let line out in 10 foot increments…waiting a few seconds for the sensor to adjust to the surrounding temperature each time you stop. Once you see the temperature suddenly drop a few degrees…you know you crossed the thermocline.

Scenario 3 (Sudden Depth Changes)…I fish in a lake where the bottom has sudden changes in depth. I know certain times of the year the big lunkers hang out right where the bottom slopes. But when I am trolling in 30 feet of water and my depth finder tells me that the water depth suddenly changed to 20 feet I have a dilemma because I am not sure just exactly how deep my lure is running. The question is…do I leave the lure where it is and risk getting hung on bottom or do I reel it in and end up way over the top of the fish hanging out on the slope? With Smart Troll there is no question. If I am trolling in 30 feet of water and I want to fish near the bottom I let my lure back until the Smart Troll Probe tells me it is 25 to28 feet deep. If I look at my depth finder and see that the water’s depth suddenly changes to 20 feet then I know without a doubt my lure is going to get caught on bottom once it catches up to where the boat was when the depth changed. So, I grab the reel and start reeling…once the Smart troll Probe tells me the lure is 15 to 18 feet I know to stop reeling so I can just barely skim over the slope…so close to the big lunkers that they cannot help but strike because of instinct.

The Smart Troll System will definitely change the way you fish with a whole new tackle box full of techniques because…Smart Trollers Know Exactly how Deep Their Lures Run.


How it works:

"Smart Troll" has the ability to tell you exactly how deep you are trolling a lure, cut bait or live the water temperature and water speed at that depth. The "Smart Troll" system includes Probes, a Hydrophone and a receiver. It is able to monitor up to 6 Probes on 6 different lines (at the same time) and is very easy to use.

  • Simply attach the small Probe to your main line (with the lure or bait of your choice attached to the other end of the leader)...or attach it to a downrigger cable, dipsy or jet. The Probe is very small and wireless so you have the freedom to use it however you want.
  • The Probe is 0.5 inch diameter and light weight (about 1 ounce in air and virtually weightless in water).
  • The "Smart Troll" Probe incorporates tiny electronic circuits that monitor the lure's depth, temperature and speed and transmits a signal through the water to the boat. Every few seconds the Probe sends an encoded  signal through the water to the transducer. The transducer sends the data to the Receiver which sends it to the user interface which in turn displays the lure's depth and the water temperature at that depth and water speed. It works GREAT at Depths well over 200 feet and with several hundred feet of line out.
