Description détaillée

Určena pro rybolov v hlubokých vodách a přesnou detekci mořského dna, průchozí bronzová sonda GARMIN Airmar B258 je 1kW řešení s možností měření hloubky a teploty vody. Pracuje na dvojím kmitočtu 50 kHz a 200 kHz, je vhodná pro trupy z laminátu nebo dřeva a připojuje se prostřednictvím 8pinového konektoru ke kompatibilním zařízením Garmin.

Technické parametry a všestrannost

Sonda B258 se vyznačuje výkonem 1 kW, který jí umožňuje dosáhnout hloubky 441 až 670 metrů na 50 kHz a až 294 metrů na 200 kHz. Její konstrukce zahrnuje čtyři keramické prvky, což jí poskytuje 25násobně vyšší citlivost ve srovnání s monoprvkovou sondou 50/200 kHz o výkonu 600 W. Eliptické svazky (14°x23° resp. 15°x21° na 50 kHz a 3°x5° na 200 kHz) zajišťují široký záběr a účinné rozlišení cílů. Oproti kompaktním modelům jako B45 nebo SS505 je B258 navržena pro plavidla od 9 metrů výše, kde je vyžadován větší dosah a lepší podmořská definice. Jedná se o robustní alternativu k CHIRP sondám řady B265/B275/B285 pro uživatele preferující tradiční pevné kmitočty s vysokým výkonem.

Instalace a hydrodynamická optimalizace

Průchozí montáž B258 je doplněna o vysokovýkonný proudnicový sabot. Ten zajišťuje laminární proudění vody pod plochou sondy, což umožňuje získat jasné a stabilní zobrazení při rychlostech až 30 uzlů (34 MPH). Sabot lze přizpůsobit úhlům trupu (deadrise) od 0° do 26° a vyžaduje otvor o průměru 30 mm (1 3/16 palce) pro instalaci hlavního tělesa sondy a otvor o průměru 14 mm (9/16 palce) pro protipootáčecí šroub, nezbytný pro stabilitu sabot. Instalace se doporučuje na trupy z laminátu nebo dřeva. B258 nabízí všestrannost pro různé aplikace rybolovu, od pobřežního a dálkového lovu až po detekci struktur a hlubokých dnů.

« Technical analysis of the Airmar B258 transducer: 1kW for deep waters »

The Garmin Airmar B258 transducer is a sound choice for sailors and anglers requiring significant deep-water detection capability without opting for CHIRP technology. Its 1 kW power and 50/200 kHz frequencies make it particularly effective for water column identification and seafloor characterization at significant depths, where a 600 W transducer would show its limits. The four-ceramic-element construction is a major asset, offering increased sensitivity and elliptical beams that improve target detection, especially in 50 kHz mode for broader coverage.

The integration of a high-performance fairing block is a key element of the B258’s usability. It is not just a protective cover but an essential component for maintaining optimal acoustic performance at high speeds. The fairing block ensures laminar flow beneath the transducer, minimizing turbulence and parasitic noise on the display, which is crucial for reading echoes during fast trolling or travel. The through-hull bronze installation restricts this model to fiberglass or wooden hulls, a point to consider to avoid electrolytic corrosion on metal hulls. The 30 mm hole for the transducer and the 14 mm hole for the fairing block anti-rotation bolt must be drilled with precision, respecting the hull’s deadrise angle to ensure beam alignment. This model is particularly suited to medium to large sportfishing boats operating regularly in open sea.

Questions fréquentes

Besoin d'aide ? Contactez-nous

What are the main features of the GARMIN Airmar B258 transducer?

The GARMIN Airmar B258 transducer is a bronze through-hull transducer rated at 1 kW, operating at 50/200 kHz frequencies. It includes a water temperature sensor and connects via an 8-pin connector. It is designed for deep-sea fishing and precise seabed detection.

What is the transmission power of this depth sounder?

The GARMIN Airmar B258 transducer has a transmit power of 1 kW (1000 Watts).

Which frequencies does this transducer use?

This transducer operates at dual frequencies of 50 kHz and 200 kHz.

What are the depth detection capabilities of the B258 fishfinder?

At 50 kHz, the depth sounder can reach depths of 441 to 670 meters. At 200 kHz, it can detect down to 294 meters.

Does the Airmar B258 transducer include a temperature sensor?

Yes, the GARMIN Airmar B258 transducer includes a water temperature sensor.

What is the particularity of the ceramic elements in the B258 depth sounder?

The B258 transducer integrates four ceramic elements, giving it a sensitivity 25 times higher than a 600 W single-element 50/200 kHz transducer.

What are the beam angles of the B258 depth sounder?

The beams are elliptical. At 50 kHz, the angles are 14°x23° or 15°x21°. At 200 kHz, the angle is 3°x5°.

For which type of vessel is the Airmar B258 transducer recommended?

The Airmar B258 transducer is designed for vessels 9 meters and longer, requiring greater range and improved underwater resolution.

How does the B258 transducer differ from CHIRP models?

The B258 positions itself as a robust alternative to the CHIRP transducers in the B265/B275/B285 series for users who prefer traditional fixed high-power frequencies.

With which hull types is the Airmar B258 transducer compatible?

The Airmar B258 through-hull bronze transducer is recommended for fiberglass or wooden hulls only.

What type of connector does the B258 depth sounder use?

The B258 transducer is equipped with an 8-pin connector for connection to your compatible Garmin equipment.

Can this transducer be installed on a metal hull?

No, a bronze transducer like the B258 must never be installed on a metal hull. This could cause electrolytic corrosion.

Does the B258 transducer require a fairing for installation?

A high-performance fairing is highly recommended if the hull deadrise angle exceeds 10°. It directs the sound beam downward and ensures clean water flow under the transducer, optimizing performance.

What is the maximum keel angle for installing the B258 transducer with a fairing?

The maximum deadrise angle for installing the B258 transducer with a fairing is 26°.

What are the dimensions of the hole to drill for the B258 depth sounder?

For the B258 transducer, the main hole to drill in the hull must be 30 mm or 1-3/16 inches. A pilot hole of 3 mm or 1/8 inch is recommended initially.

Is an anti-rotation bolt required with the fairing?

Yes, installing the anti-rotation bolt is mandatory with the high-performance fairing. This bolt firmly secures the fairing in place and prevents it from rotating during navigation. The hole for this bolt must be 14 mm or 9/16 inches.

How to position the fairing on the hull?

The fairing must be installed parallel to the keel. The end of the fairing with the arrows or triangular recess must always point forward (toward the bow) of the boat.

What precautions should be taken when applying antifouling paint to the depth sounder transducer?

It is recommended to use a water-based antifouling paint, mandatory in saltwater. Airmar certifies that applying Foulfree coating does not affect the transducer's performance. This coating is non-toxic, creates an ultra-smooth surface, and prevents marine growth from adhering, ensuring optimal performance.

Where should the depth sounder be installed on the boat for optimal performance?

The transducer must be installed in an area where the water flow is smooth, with minimal bubbles and turbulence, and always submerged. It must be at least 300 mm (1 foot) away from the keel and propellers/shafts to avoid interference. For powerboats, it is typically placed just forward and to the side of the engines, or ahead of the propellers for inboards.

Is it necessary to check waterproofing after installation?

Yes, it is imperative to check immediately for any leaks when the boat is launched. The boat should not be left unattended for more than three hours after launching, as even a small leak can accumulate a significant amount of water.
