Navigator for PVC boat: selection, installation and configuration of sonar

Going out on the water on an inflatable boat has ceased to be just a way to spend time in nature, turning into a serious hobby that requires technical equipment. PVC boat navigation Today, it is not a luxury, but a necessity, especially if fishing or hunting takes place in unfamiliar water bodies or in conditions of poor visibility. Modern devices combine the functions of a GPS tracker, mapper and sonar, allowing you not only to stay lost, but also to efficiently find fish.

Choosing the right device can be confusing even for an experienced boatmaster, due to the sheer number of specifications, brands and price categories, including the size of the vessel, engine type, budget and specific tasks you plan to solve on the water. In this article, we will discuss all the nuances of choosing, installing and operating navigation equipment for inflatable boats.

Errors in the buying phase often result in the appliance becoming a useless load or quickly failing from moisture and vibration. Garmin, Lowrance, Humminbird These names are familiar to many, but what format is suitable for your PVC boat? Let's figure out consistently, so that your voyage is always safe and effective.

Key criteria for choosing a navigator for an inflatable vessel

The first thing to look at when buying is the form factor and the way it attaches. For PVC boats, which often have to be pulled ashore, transported in the trunk and inflated again, a stationary insert into the side is not always convenient. Mobility As the device becomes a priority, many people choose models with suction cups or mounting on a transom bar, the screen should be readable in bright sun, and the case should have reliable protection from spray and dust.

The second critical parameter is autonomy: If you plan long exits without recharging from the onboard network, the built-in battery may not be enough for a whole day of active navigation with the screen on and the GPS module running. Time to work. It depends on the diagonal of the screen and the brightness of the backlight, and it is also worth paying attention to the presence of a memory card slot, since the built-in memory is often not enough to load detailed maps of the bottom relief.

⚠️ Note: Not all navigators have a built-in sonar. If the model name does not indicate sonar or a sensor in the kit, it is likely only a GPS mapplotter that requires an external sensor.

The third aspect is the sensitivity of the receiver, and the standard GPS module is suitable for a calm swim on the river, but for sea fishing or movement in narrow narrow currents, support is required. GLONASS The antenna can be taken to the most open place on the boat, providing a stable signal even in heavy clouds or in wooded shores.

Types of navigation devices and their functionality

The modern market offers several classes of devices, each of which is sharpened for specific tasks, the basic option is a simple GPS navigator, which shows only coordinates and tracks. mapplotters It's also supported by vector or raster maps, and it allows you to see depth, types of bottom, and navigational signs.

The most popular solution for PVC boats is a two-in-one or three-in-one combine: a navigator plus a sonar, which can be equipped with a transom sensor or have a built-in sonar (although the built-in sensors are less efficient at high speeds). CHIRP Technology In sonars, you can get a clearer picture and separate targets, which is critical when searching for fish among driftwoods.

And it's also smart navigation, which is the use of tablets and smartphones with external GPS modules, which is a budget option, but it has a significant drawback: consumer electronics screens are often hard to read in the sun and afraid of moisture. glare-coating and IPX7 sealing, which ensures their survival in harsh conditions.

• 🌊 Monoblocks - all in one case, convenient for installation, but require supply of power to the installation point.
• 📡 Separate systems - remote screen and a separate processor unit, allow you to flexibly place the equipment in the cockpit.
• 📱 Mobile solutions - the use of gadgets with waterproof cases and external Bluetooth antennas.

Overview of popular models and brands for PVC boats

The company has been a market leader for many years. GarminIt's a device that's famous for its positioning accuracy and map detail. Striker or Echomap They're compact, they have a user-friendly interface, and they often come with a transducer to be mounted on a transom, and they're priced above average, but they're reliable.

Brand Lowrance offers a great alternative with a focus on fishing features. Hook They are designed specifically for amateurs, they are easy to control and have a powerful echolocation module. DownScan Technology allows you to see the structure of the bottom almost as in the photo, which helps to find the depth changes and bottom vegetation.

Chinese manufacturers, such as Humminbird (although American, often localized) and various OEM brands offer affordable options, which may be inferior in screen refresh rate and plastic quality, but functionally often copy top models, and when choosing a budget segment, it is important to check the actual tightness of buttons and connectors.

Comparative table of specifications of navigators

To organize information and simplify the selection, we compare popular categories of devices in tabular form. Note that the specifications may vary depending on the specific modification and year of release.

When you look at the table, you can see that the premium premium segment overpayment is often driven less by GPS accuracy than by image quality and additional scanning features. For a PVC boat up to 3.5 meters long, it will be redundant to buy a 9-inch screen device, as it will be difficult to place in the limited space of the cockpit.

Rules of installation and installation of equipment on the transom

Installing a navigator on an inflatable boat has its own specifics, different from mounting on rigid boats. The main rule is to ensure that you can quickly dismantle. The use of permanent glue or drilling holes in cylinders is strongly discouraged. The ideal solution is to use a transom strip made of plastic or stainless steel, which is attached with rods.

The sonar sensor also requires proper placement, and on the transom of PVC boats it is usually attached with a special bracket-pin or suction cup, so that when hitting an obstacle, the sensor deflects, not breaks, and the cable must be arranged so that it does not interfere with the movement of the boat and does not rub against the side. Sealing compounds - a mandatory step, even if the connectors have plugs.

Power is best provided through a separate connector that can be quickly turned off, and the wiring should be placed in a corrugated or cable channel, especially in areas of contact with inflatable elements, to avoid damage to the balloon. If the boat does not have a hard bottom (plywood), a small deck can be provided under the screen.

Field maintenance and protection

Water and electronics are incompatible, so the PVC boat's navigator should be regularly maintained. After each release, even if the device has a high protection class, it should be wiped with fresh water (especially after fishing at sea or in salt water) and wiped dry with a soft cloth. Salt and fish mucus can erode the button seals.

Store the device in a dry room, removing memory cards and disconnecting the cables. Periodically check the condition of the sealing rubber bands on the back cover and in the connectors. If you notice a clouding of the screen or condensation inside the case, immediately stop using and dry the device, otherwise contact-corrosion It will have irreversible consequences.

⚠️ Warning: Never leave your navigator in direct sunlight on a boat off on a hot day. The internal temperature may exceed the permissible temperature, causing the battery to bloat or deform the screen.

To extend battery life, don’t discharge your lithium-ion batteries to zero. If you don’t plan to use your navigator during the winter season, charge it to about 60-70% and store it in a cool place, periodically checking your charge level.
