Deciding exactly where to mount a transducer on a pontoon boat can feel a bit like a questioning game if you haven't done it before. Unlike a standard V-hull fiberglass boat where there's usually an obvious "sweet spot" from the bottom from the transom, pontoons present a bit of a geometric challenge. You've got 2 big aluminum wood logs (or three, if you're rocking a tri-toon) and a whole lot of empty area in between. When you place it within the wrong location, you'll end up with a screen full of "noise" or a transducer that kicks upward a massive roostertail of water every time you hit 10 mph.
The goal is to find a spot where the drinking water flows smoothly below the transducer. In case the water is usually turbulent or filled with air bubbles, your own fish finder is going to struggle to give you a clear picture. Here's a breakdown associated with how to find that perfect mounting location and get your sonar operating exactly how it should.
Search for the Factory Bracket First
Most modern pontoon logs include a pre-welded mounting group on the trailing edge of just one associated with the pontoons. In case your boat has one of these brilliant, that's almost always where you should start . Manufacturers usually weld these on the particular rear from the starboard (right-hand) log.
The reason they will choose the starboard side is fairly simple: most outboard propellers rotate clockwise. What this means is the water on the correct side of the motor is being pressed downward, while the water on the left side will be being pulled upwards. That upward draw on the opening side often produces more bubbles plus turbulence. By adhering to the starboard log, you're providing the transducer a better shot in "clean" water that will hasn't been churned up by the prop yet.
If you don't have a factory group, don't panic. A person can buy aftermarket brackets that clamp onto the journal or even use a specialized cement adhesive mount, though most people prefer a solid, permanent remedy. Just make certain you aren't going straight into the pressurized log itself—that's a recipe for a very costly sinking feeling.
The Importance associated with Clean Water
I mentioned "clean water" already, yet it's worth double-checking what that actually indicates for a pontoon. When a pontoon moves through the particular lake, the circular form of the records creates a particular flow pattern. You want the transducer to sit within water that hasn't been disturbed by anything else on the hull.
Keep an eyesight out for: * Strakes or fins: If your own pontoon has raising strakes (those lengthy metal fins welded to the edges or bottom associated with the logs), a person need to guarantee the transducer isn't seated directly behind one particular. * Rivets and weldings: Actually a small sticking out weld a few feet in front of the transducer can create a stream of bubbles at high speeds. * The engine: You would like the transducer considerably enough away from the particular motor so it doesn't pick up electrical interference or bodily turbulence from the particular prop.
Ideally, the face of the transducer should end up being slightly below the particular bottom of the pontoon log. If it's too high, it'll be tucked upward in a pocket of air. When it's too reduced, it'll catch every bit of particles in the lake and create a massive splash that will might even dip the passengers within the back chair.
Setting the proper Height and Position
Once you've found the place, the exact positioning will be the next hurdle. You'll want the particular transducer to become level using the waterline when the boat is sitting nevertheless, but here's the particular kicker: boats don't sit perfectly degree when they're shifting.
Most pontoons tend to "nose up" a little bit when they're cruising. Due to the fact of this, many people find success by tilting the back again of the transducer lower just a small bit—maybe a few degrees. This assists the face from the sensor stay within constant contact along with the water instead of skipping along the surface.
For your height, begin with the transducer half-submerged below the bottom edge from the log. If you're getting a lots of "surface clutter" on your own screen at high speeds, try decreasing it by a quarter-inch. If it's throwing a huge spray of water up to the surroundings, it's probably too deep or tilted too aggressively. It's often a video game of learning from mistakes; maintain a wrench on the boat intended for your first outing so you can make small changes on the fly.
Mounting on the Trolling Electric motor
If you're a serious angler and you invest most of your own time on the bow from the boat, you might consider mounting a second transducer on your own trolling motor. This provides you a "real-time" view of what's directly under the particular front of the boat rather than what's 20 feet behind you.
This is a popular choice for "vertical jigging" or when you're trying to stay right on top of a specific brush pile. The downside? A person only get a signal when the trolling motor is deployed in the drinking water. Most people that go this route keep a major transducer on the rear log for navigating and a secondary one on the trolling engine for actual fishing.
Coping with the particular Wiring
Really figuring out where to mount a transducer on a pontoon boat is only half the fight; then you possess to deal along with the cable. Pontoons have a lot of exposed places, and you don't want 20 ft of transducer wire dangling under the particular deck where it can get snagged on a stump or chewed on by a stray muskrat.
The simplest way to handle this is to run the wire up the particular back of the log and by means of the "C-channel" or the aluminum cross-members that will support the floor. Use plenty associated with UV-rated zip ties to keep almost everything tight against the particular frame. Most pontoons have a corrugated plastic or aluminium "skin" on the particular bottom (underskinning). In case your boat has this particular, you can generally fish the wire with the gap among the skin and the deck. It's a bit of a pain to pull the wire all the way to the helm, but it's a lot better than having a loose cable flapping within the wind.
Avoid the "Center associated with the Logs"
One common mistake I see will be people trying to mount the transducer to the underside of the deck, best in the center of the two logs. It appears as though a safe, protected spot, but it's really the worst place for sonar.
When a pontoon moves, the space between the logs is a chaotic mess of splashing water plus air. It's generally a washing device under there. Sonar waves cannot travel through air bubbles effectively. In case you mount it there, you'll likely get a great reading while sitting at the pier, but the time you put the boat in equipment, your screen may go blank or even show only static. Always stick to the trailing advantage of the real log.
Examining and Fine-Tuning
Don't get disappointed if your very first trip out isn't perfect. Pontoons are usually notorious for being finicky with sonar. If you're shedding depth readings from high speeds, it's almost always because of air bubbles. Attempt nudging the transducer down a little bit deeper into the particular water.
If you're worried about the transducer getting knocked off by a submerged sign or a stone, you can consider "spring-back" brackets. These types of allow the transducer to flip up if this hits something, helping you save from getting to buy a new one every single time you endeavor into the shallows.
In the particular end, it's almost all about finding that pocket of easy, undisturbed water. Once you find this, you'll be capable to see every contour of the particular lake bed plus every fish hiding in the weeds, making your time on water a whole lot more productive. Just take your time and energy with the alignment, retain it on the starboard sign if possible, create sure your wires is tucked away safely. Happy fishing!
