Effective fishing on inflatable boats is impossible without high-quality navigation and understanding of the bottom relief, so sonar-holding Unlike rigid aluminum or fiberglass housings, PVC materials require a special approach to fixing equipment, because standard drilling methods do not apply here. A properly selected and installed holder will not only protect expensive electronics from falling into the water, but also provide a stable signal from the bottom without interference from air bubbles.
There are many ways to fix the device, from the simplest removable structures to complex swivel mechanisms integrated into cylinders. flyboatIt is important to understand that improper installation can lead to damage to the transom or loss of signal, so the question should be approached systematically.
⚠️ Warning: Before buying or manufacturing a bracket, make sure that the selected installation location will not block access to air or water discharge valves, as this is critical for water safety.
Criteria for choosing the type of inflatable board anchorage
When choosing a method of fixing equipment, you need to take into account the design features of your boat. transom board PVC is often less thick in boats than metal counterparts, requiring the use of gaskets or specific clamps to prevent deformation, and the presence of an inflatable keel, which can interfere with the installation of stationary sensors in the central part, should be noted.
Mobility is another key factor: If you carry the boat frequently or use it for different purposes (such as spinning and trolling), you may need to be able to use it. mountFor those who prefer stationary, permanent fixation options that require more complex preparation, but provide maximum rigidity, are suitable.
- 🎣 Type of transom: Hard insert or soft PVC requires different approaches to clamping.
- 🎣 Dimensions: Larger screens need more powerful brackets.
- 🎣 Frequency of operation: for rare trips, temporary fixation is suitable, for professionals - permanent.
The screen should be readable in any light, and the control buttons should be at hand, even if the boat is cruising on the wave. The optimal distance from the water to the sensor for most sonars is 15-20 cm, which provides a clean signal without air bubbles.
Overview of the main types of holders for echoers
The accessories market offers a wide range of solutions, among which the leading transom brackets. This is a classic version, which is a metal or plastic bar that is attached to the top slice of the transom. transom mounting universal and suitable for most models, but requires a rigid insert in the transom.
The second popular option is the rotary mechanism, which allows you to throw the sensor up when you go out in shallow water or when you transport it, which saves the sonar from hitting the bottom. spring-shock-absorberIt dampens vibrations and protects sensitive electronics.
There are also specialty mounts that are mounted directly on cylinders, which are platforms with Velcro or belts, but their use is limited to sonar models with wireless sensors or built-in batteries, since it is not always convenient to pull wires through the side.
Necessary tools and materials for installation
Before you start installation, you need to prepare all the components. To work with PVC materials and metal, you need a toolkit that allows you to install it accurately and reliably. Do not use sharp objects near inflated cylinders unless absolutely necessary.
The main list of tools includes a drill (if you plan to drill a trans board), a set of screwdrivers, wrenches and a sealant. sealant, which must be resistant to ultraviolet light and salt water to prevent corrosion and leakage.
☑️ Preparation for installation
To protect the wires from rubbing against the side or sharp edges of the transom, be sure to prepare insulating tape, thermal shrinkage or special Cambrians. The wire should be flexible and frost resistant so as not to crack in the cold.
Step-by-step instruction: installation of transom fastening
The installation process begins with the mounting site marking, attach the bracket to the transom and mark the drilling points, making sure they are far enough from the edge to not split the material. If the transom has a soft skin, attach a wooden or plastic gasket to distribute the pressure.
Drill holes with a diameter corresponding to the fastening bolts. Insert bolts on the inside of the boat, pre-laying the layer silicone sealant Put on a bracket on the outside and tighten the nuts, but don't pull them over so you don't deform the transom.
| Work phase | Action. | Important feature |
|---|---|---|
| Markings | Definition of centre and height | Water level recording during the course |
| Drilling | Creating bolt holes | Use of metal/wood drill |
| Hermetization | Application of composition | Required for all holes |
| Fixation | Pulling the nuts. | Control of the tightening force |
After installing the mechanical part, attach the sonar itself to the holder according to the manufacturer's instructions. Check the reliability of the fixation by shaking the structure with your hand - there should be no backlashes.
Nuances of working with soft transcen
If your boat has a completely soft transom without a hard insert, you can not drill it. In this case, use special pressing slats that cover the soft part of the transmuner on both sides, or consider installing a sensor on a rental set attached to the stringers or bottom.
Alternative methods: removable and rotary systems
For those who don't want to drill a boat, removable systems based on powerful clamps are a great solution, and they are fixed to the top of the transom using a screw mechanism, without requiring any disruption to the integrity of the material. bracket They are easily transported between different boats.
Flip-ups are particularly relevant for PVC boats because they allow the sensor to be quickly removed from the water, and this is true when approaching shore, overcoming rolls or pulling a boat onto a trailer, and the mechanism usually consists of a movable axis and a hold.
- 🛶 Advantages of removable systems: no holes, versatility.
- 🛶 Pros of turning mechanisms: sensor protection, ease of transportation.
- 🛶 Cons: higher price and complexity of the design compared to statics.
When selecting a rotary mechanism, make sure the spring is tight enough to keep the sensor in working position when moving, but allows it to be thrown back with your hand if necessary.
⚠️ Attention: When using removable mounts on screw clamps, regularly check the tightening of the screws, since the vibration of the motor can gradually weaken the fixation, which threatens the loss of the sonar.
Cable laying and connection protection
The quality of the image on the screen depends on the condition of the cable. When laying the wiring, avoid tension and sharp inflections. The cable should be fixed along the side or transom using plastic clamps or special clips, providing a small margin of length for free travel.
The connection locations, especially if you've lengthened the regular cable, should be carefully insulated. shrink-tube It's a glue layer that, when heated, creates a monolithic, waterproof compound, and the regular insulation in water quickly loses its properties.
Inside the boat, it is better to put the cable in a plastic box or fasten it under a jar so that it does not get confused under your feet, which is not only aesthetically pleasing, but also safe, since it eliminates the risk of catching your foot and pulling the device out.
Maintenance and seasonal storage of equipment
After each fishing, the mount and the sonar require maintenance. Fresh water washes away salt and dirt, and wiping with a soft cloth prevents scratches on the screen. Pay special attention to the movable parts of the bracket - they are recommended to be periodically lubricated with silicone lubrication.
For winter storage, it is better to dismantle the sonar completely, even if the mount remains on the boat, the battery is stored in warmth, and the device itself is stored in a dry place. If the bracket is metal, check it for corrosion and paint the chips if necessary.
Regularly checking fasteners before the start of the season will avoid water troubles. Make sure that all bolts are tightened and the plastic has no cracks from ultraviolet light or mechanical influences.
Timely prevention of corrosion and checking the tightening of bolts prolong the service life of the sonar fastening by 2-3 times.
Frequently Asked Questions (FAQ)
Can I attach the echo sounder directly to the inflatable balloon?
Mounting a heavy appliance directly onto a soft tank is not recommended, as it can damage material and disrupt the boat's balance, but there are special lightweight Velcro platforms for compact wireless sensors that can be temporarily fixed on board.
How to protect the echo sounder from splashes and rain?
Most modern sonars are IPX7 protected, allowing for short-term immersion, but it is better to use a protective visor or cover to protect against constant splashes and salt, and also to wipe the screen after fishing.
Do I need to remove the sensor when driving at high speeds?
Yes, when speeds are higher than 15-20 km/h, it is recommended to raise the sensor to avoid cavitation interference (air bubbles), which make readings useless, and reduce the risk of the sensor hitting underwater obstacles.
Which cable is best used for lengthening?
To lengthen, you should use a specially shielded cable of the same cross section as the regular one, and it is important to observe polarity and use high-quality soldering with subsequent sealing, so as not to lose the signal.
