How many depth finders do you really need? If you’ve never asked someone that question, you’ve probably never seen the boats of National Guard pro Mark Rose or his friend and three-time EverStart Series winner Randy Haynes of Counce, Tenn. Each rigs his boat with four 10-inch Lowrance HDS units. Heck, Rose even adds a fifth unit, a 5-incher, at the bow.

Mark RoseBy now, you probably really are wondering how many depth finders they need. Before you get an answer, however, consider this: During the past six years, Rose and Haynes have combined to win more than $1 million, clinch 10 tournament titles and log 32 top 10s in FLW competitions. They credit their success to their ability to catch fish offshore. And electronics are a key tool for them to find and catch fish in all that water.

“About five years ago, I began noticing that by the third and fourth days of these four-day tournaments, the shallow-water stuff was picked over,” Rose says. “I noticed that people like David Fritts and other off-shore fishermen I watched on TV would catch five in five casts, while I was fishing all day for five bites. I knew the offshore game was going to be an advancement of the future, and I made a conscious effort to learn all that I could about it.”

Learn Rose did, and he’s willing to pass along some of what he’s learned. For starters, check out how he and Haynes rig their Rangers with electronics.

A. Transom Transducers
The dash head units are connected to a transducer on the transom. This is also where the StructureScan transducer, which includes SideScan and DownScan, is mounted.

B. GPS Receivers
Haynes’ GPS units all run off one receiver, which is mounted near the transom. Keep in mind that the trolling motor, with its transducer, is about 20 feet from the receiver, so occasionally it’s necessary to make adjustments when pulling up to a waypoint while standing on the front deck.

Rose uses two receivers – one at the stern and one installed on the bow by the trolling motor. He feels this setup allows for more accurate waypoint generation and fishing.



Randy HaynesC. Batteries
Both pros suggest “thinking big” when buying batteries. Get the largest reserve capacity available. And don't scrimp on the number of batteries, either. Haynes has four in the boat –
three for the trolling motor and one for the depth finders and livewell, and for starting the big motor.

When fishing at the bow, one way to conserve battery power is to set the dash units to standby mode.

D. Dash Units
Each pro has two HDS-10 units at the dash – one installed into the dash and the second installed off to the right on a mount. These are the primary search tools.

One unit is split with the left- and right-side StructureScan views on one half and the DownScan view on the other half. The second unit is split between the GPS map and traditional 2-D sonar.

E. Ethernet Box
Both pros rig up Lowrance’s “little black box,” a well-designed device that allows StructureScan HD sonar to be distributed to three head units and to share waypoints across units. It can be
stowed in a compartment, usually near the console.

The Most Important Tool

Before rushing out and dropping thousands of dollars on electronics equipment,stop and consider the most important tool that pros Mark Rose and Randy Haynes have working for them: experience.

“It’s like everything else, it takes time on the water,” Haynes says. “It takes a while to get it all processed, where you just glance at it and know what’s going on.”

Rose echoes his sentiments and recalls the time he spent learning to use modern fish-finding technology.

 

“I made a conscious effort to learn all that I could about it from people that were good at it,” he says, “and I got involved with Lowrance electronics, which allowed me to get better at it. I spent a huge amount of time on the water honing my skills. That’s the biggest key – not listening to everybody all the time. Find a few people that are really good at it, and then take what they teach you and hone it on your own.”

F. Bow Units
It used to be that the main function of depth finders was to find structure, not fish. But Rose and Haynes are way past that. They have multiple units at the bow to see what’s under them, to spot many of the fish they catch, and even to use multiple maps.

Haynes rigs two 10-inch units at the bow. Rose does the same but adds a 5inch unit (he’ll have a third 10-inch unit in 2013) that installs into the “dash.”

Together, the units provide a complete view of the “big picture.”

There are different ways to set up the screens on the dash units. For instance,
Haynes usually has a DownScan and StructureScan set up on at least one unit at all times. Rose typically has a full-screen map and a full-screen sonar on his HDS-10s and a second map on his HDS-5. He turns on StructureScan only when he thinks he needs it.

Haynes suggests mounting one bow unit in front of the trolling motor pedal and the other off to the side, so that it’s tucked behind the trolling motor when the trolling motor is stowed. If he “stuffs” a wave while running, the motor protects the unit and helps keep it from being ripped free.

2 Reasons for 2 Units


If you still think it’s crazy to have two 10-inch units at the dash or at the console, consider what pros have on the line in tournaments. They’re fishing for major money and career success. Having two units in each place gives them a couple of major advantages.


Built-in backup
– If one unit goes out, the backup unit is already installed and working.

Multiple views – This is a big one. The more ways an angler can “see” the bottom and the fish, the better understanding he’ll have of what’s in the area.

G. HydroWave
HydroWave units emit sounds that imitate forage fish and feeding predators that bass can feel in their lateral line and inner ear. The HydroWave is a source of speculative discussion among
many anglers. Does it help, or doesn’t it? Rose and Haynes have a HydroWave unit on their boats.

“You really don’t know if it helps, but it sure doesn’t hurt anything,” Haynes says. “It probably helps cover some of your boat noise, such as the transducer popping. If I don’t catch something, I’ll turn it on.”

Rose says he was skeptical of HydroWave at first, but after installing a unit, he rattled off five top-10 finishes, including a victory at Pickwick.

“Those were my first experiences with the HydroWave, and I was pretty much sold after
that,” he says. “I’m not going to sit there and tell you that if you put one on the boat, fish are going to jump in the boat and you’ll catch more fish, but I will tell you that you can get everything around the boat excited – the shad, the baitfish, the bluegill. You’ll start seeing your screen wake up.”

Both pros suggest experimenting with the unit. Sometimes it seems to make a difference, at other times factors such as boat positioning or crankbait selection take precedence. There is no “blueprint” for how to use it.

H. Trolling Motor Transducer
Both pros use MotorGuide trolling motors outfitted with built-in sonar transducers with an additional transducer attached to the trolling motor head so that they each have a backup.
Haynes uses the built-in transducer first; Rose uses the add-on transducer first.


Sonar Separation


Pro Randy Haynes’ DownScan and StructureScan information, both at the bow and the dash, channels through the StructureScan transducer mounted at the transom. Yet his 2-D sonar transducer for the bow unit is in the trolling motor. That means he’s getting information from transducers spaced 20 feet apart. It might seem like that’s a bad thing, but Haynes says that’s not necessarily the case.

 

“This gives me 20 feet of coverage from front to back,” he says. “Sometimes it makes a difference. When you catch a fish and some come out with it, those fish show up as streak marks when you bring the school up. You might miss them with your trolling motor transducer. But when that StructureScan shoots out there you can see the streaking and can back off and still catch them.”
