Properly mounting sonar is the foundation for getting a good picture of the bottom and finding fish. Many anglers underestimate the importance of reliable fixation of the sensor, relying on temporary solutions or "hurried" designs made. However, when a boat is on the wave or at high speed, it is the quality of the fastener that determines whether fishing will continue or will have to return to shore with damaged equipment.
Echo-flashers PractitionerThe 6M, 7, 9 and 10 models, especially popular ones, require a clear positioning of the emitter relative to the water surface. The slightest roll or surfacing of the sensor leads to loss of signal and the appearance of "noise" on the screen. In this article, we will discuss all existing methods of installation, analyze their pros and cons, and give recommendations for choosing the best option for your PVC boat or metal boat.
Particular attention should be paid to the compatibility of the chosen method with the type of boat you are using. What is ideal for an inflatable boat with an outboard motor may not be acceptable for a boat with a fixed propeller or a boat with a hard bottom. There are no universal solutions.Each case requires an individual approach and taking into account the specifics of operation.
Types of fasteners for sounders Practice
The fishing accessories market offers several major categories of fixtures, each with its own design features, depending on whether you plan to remove the appliance after each fishing trip or leave it on the boat for the whole season, and whether you will move the sonar between different boats is also important.
The most common option is transom-holdingIt's a bracket that can be mounted directly onto the transom of a boat, and it's a classic solution that's been tested for decades, and it keeps the sensor stable, but it has its own limitations on angle of turn and altitude of lift.
⚠️ Warning: When choosing a transom mount, make sure that the length of the lever allows the sensor to drop below the level of the motor keel, otherwise you will constantly catch air bubbles instead of fish.
The second popular type is suction-bagThey're very convenient for smooth boats, and they allow you to quickly move the sensor from one side to the other. stationaryThis is a method that is more commonly used on metal or fiberglass boats.
- 🔹 transom brackets are classic, reliable, but require drilling of a transom.
- 🔹 Suction cups are mobility and lack of drilling, but the risk of peeling off at speed.
- 🔹 Cutting sensors are ideal hydrodynamics, but the impossibility of permutation.
- 🔹 Clamping structures - suitable for boats with a rigid bar along the side.
Each type has its own hydrodynamic specificationsFor example, remote brackets create greater water resistance, which can be seen on low-power motors, while the cut-in sensors have little effect on the boat's progress, but they require high skill.
transom brackets: features of installation
Installation on a transom is the most common way to install sonars Practitioner The design usually consists of a vertical barbell and a rotary mechanism to adjust the depth of the emitter. It is important that the bracket material is resistant to corrosion, as constant contact with water and the sun destroys poor-quality alloys.
You'll need to drill holes in the transom to install it, and if the boat is inflatable, you'll often use plywood or plastic linings that are attached to the cylinder and you'll have a bracket mounted on them, which avoids direct drilling of rubber or PVC, which is especially true for new boats that are under warranty.
The key point in the installation is pole-lineIf the bracket is set at an angle, when the boat moves, the sensor will start to pop up or, conversely, go too deep. The adjusting screws must be tightened with moderate force so that they can be twisted on the water, but they do not unwind from vibration.
- 🛠️ Use stainless bolts and nuts to fasten the bracket.
- 🛠️ Treat the drilling sites with a sealant to prevent moisture from entering.
- 🛠️ Make sure the cable does not RUB against the edge of the transom when moving.
Some anglers make their own aluminium profile brackets, which allows them to create a design that fits perfectly for a particular boat. Practitioner or compatible analogues usually have better-developed ergonomics and a cable fixation system.
Fixing on suction cups: pros and risks
Suction cups are a trade-off between convenience and reliability, ideal for those who don't want to drill their boat or change their boats frequently. Modern vacuum valve suction cups can withstand considerable loads, but their reliability depends on the purity of the surface of the board.
The main risk of using suction cups is the possibility of peeling off when a grain of sand hits or when a boat jerks abruptly on the wave. Losing the sensor in the water is an unpleasant scenario, so experienced users always use the same method. tetherEven if the suction cup lets go, the sensor will remain on the insurance and will not sink.
⚠️ Warning: Never rely solely on the suction force of the suction cup when driving at high speeds. Always use an additional safety fold tied to a loose bolt or leer.
To work effectively, the suction cups must be smooth and fat-free, and PVC boats with a relief structure of fabric or with stringers glued can be difficult to install, and in such cases you can use special transition plates that are glued on board permanently, and already on them is put a suction cup.
The secret to a reliable sucker
Wet the suction cup not with water, but with glycerin or soap solution - this will improve tightness and prevent rubber from drying out in the sun.
The advantage of this method is the ability to quickly transposition This is useful for fishing with different winds, when one side more throws on the wave, and the picture on the screen becomes unreadable due to air bubbles.
Comparative analysis of installation methods
To make an informed decision, you need to compare the main specifications of the different ways of attachment. The table below shows the key parameters that will help you decide on the choice of equipment for your boat.
| Parameter | transom bracket | Suction cup. | In-line sensor |
|---|---|---|---|
| Difficulty of installation | Medium (to be drilled) | Low (sticked and all) | High (tick in required) |
| Reliability at speed | High. | Medium (requires insurance) | Maximum |
| Mobility | Low (hard to remove) | Tall (taken in a second) | Missing. |
| Impact on boat progress | Creates resistance | Creates resistance | It doesn't. |
As you can see from the table, squirt It's the middle ground for most anglers, it's pretty reliable and stable, it's the cut-in sensors that are for expensive boat owners, where aesthetics and speed are more important than mobility, and it's good for testing or temporary use.
The cost of each method is also considered: transom brackets are inexpensive, but require the purchase of additional consumables (sealer, bolts); the inset may require the services of a specialist, which greatly increases the cost of the process; Suction cups are cheap, but require the purchase of a quality model so as not to lose the sensor.
For 80% of owners of PVC boats, the best choice is a combined method: a transom bracket with the ability to quickly remove the barbell.
Instructions for the installation of the sonar Practice
The installation process can be divided into several consecutive steps. Sequence disruption can lead to the need to redo the work, so follow the instructions carefully. Before starting work, make sure that you have all the necessary tools: drill, drill, screwdriver, sealant and marker.
First, you need to determine the place of installation, it should be such that the cable does not interfere with the control of the engine and does not get confused under the feet. Mark the holes for fasteners. If you use a wooden pad on a transom, drill holes in it, apply to the boat and through them mark the attachment places to the cylinder or transom.
☑️ Pre-installing check
Then there's the direct installation step, and you can apply a sealant layer to the bolt thread or to the surface of the lining, and you can prevent water from entering the structure of the boat material, you can set the bracket and tighten the fastener, and you can't pull the bolts around so that you don't damage the transom material.
- 📍 Mark the mounting points taking into account the course of the jet from the screw.
- 📍 Drill the holes with a smaller diameter drill, then drill to the desired.
- 📍 Set the sensor, align it vertically and fix it.
- 📍 Lay the cable so that it does not stretch when turning the bracket.
Once installed, be sure to do water testing. Check the sounder at different speeds. If the image starts to crumble or vertical stripes appear, try lowering the sensor deeper or changing its position relative to the water flow.
Typical errors and troubleshooting
Even experienced anglers sometimes make mistakes when mounting equipment. One of the most common problems is the wrong orientation of the sensor. The emitter has to look downwards. If it's skewed, the beam will bounce off the surface of the water or the bottom at an angle, creating dead zones.
The second common mistake is cable-antennaThe cable from the sensor to the sonar unit should not be hinged near the engine or other sources of interference, but can act as an antenna, catching tips that are displayed on the screen as noise, and the cable should be tightly stacked along the side, fixing it with tape or screeds.
⚠️ Warning: Do not run the sonar cable parallel to the power cables of the motor. the distance between them should be at least 20-30 cm to avoid electromagnetic tips.
There is also a frequent problem with air-bubblesIf the sensor is set too high or there is an obstacle in front of it (for example, the head of the transom bolt), the resulting bubbles will shield the signal. The solution is one - lower the sensor lower or smooth out the contours in front of the sensor.
If you see vertical white stripes on the screen that move from left to right, it's a sign of cavitation, lower the sensor deeper or reduce the speed of the boat.
Check the condition of the fasteners regularly. Vibration and water do their job, and through the season of operation, the nuts may weaken. Preventive inspection and tightening of threaded joints will prolong the life of your equipment and save you from losing the sonar at the most inopportune time.
FAQ: Frequently asked questions
Can I use the practising echoer in winter when mounting on a boat?
Yes, sounders Practitioner operate at low temperatures, but lithium-ion batteries can lose charge quickly. It is recommended to keep the device warm until the moment of release to the water and use an insulated case for the control unit.
How long is the cable required to install on the transom?
The standard cable length (usually 2-4 meters depending on the model) is often enough to be mounted on a transom. If you make a high remote bracket, you may need to lengthen, which can be done yourself using water-resistant soldering.
Does the color of the sensor affect the sounder?
No, the color of the sensor body does not affect the passage of the ultrasonic signal, but light sensors are less heated in the sun, which may be important for the durability of plastic in hot weather.
Do I need to lubricate the moving parts of the bracket?
Yes, it is recommended to periodically lubricate the axes of rotation with silicone lubrication, which will prevent the mechanism from souring and allow easy adjustment of the position of the sensor even after prolonged downtime.
