Detailed description

Paket dviju prolaznih sondi Raymarine B175 D/T Low-Medium 20° (šifra T70076) namijenjen je pomorcima i profesionalcima koji zahtijevaju performanse ehosondiranja CHIRP od 1 kW. Svaka sonda, izrađena u robusnom brončanom kućištu, integrira CHIRP tehnologiju na niskim (40-60 kHz) i srednjim frekvencijama (80-130 kHz), omogućavajući višenamjensku detekciju u dubokim i priobalnim vodama. Transduktor B175LM ističe se mogućnošću pružanja podataka o dubini i temperaturi, ključnih za navigaciju i ribolov.

CHIRP performanse i prilagodljivost

Snom snagom od 1 kW, sonda B175LM osigurava superiornu rezoluciju ciljeva i poboljšanu separaciju odjeka u usporedbi s konvencionalnim sondama od 600 W, poput serije B75. Niska frekvencija (40-60 kHz) optimizirana je za prodiranje u duboke vode, s promjenjivim snopom od 24° do 16°. Srednja frekvencija (80-130 kHz) osigurava detaljnu detekciju ribe i struktura u srednjim dubinama, s snopom od 16° do 11°. Svaka sonda u paketu ima keramički element nagnut 20 stupnjeva, što korigira kut trupa za brodove s V-kobilicom između 16° i 24°, osiguravajući precizan vertikalni snop za optimalno očitavanje.

Integracija i postavljanje

Ovaj paket sondi integrira se s CHIRP ehosondirnim sustavima Raymarine, uključujući module CP470 i CP570 te multifunkcijske ekrane serija Axiom i Element Pro. Za razliku od sonde B75 koja nudi 600W, B175LM od 1kW namijenjen je aplikacijama koje zahtijevaju veću snagu i dubinu. Prisutnost dviju identičnih sondi u ovom paketu (T70076) omogućuje napredne konfiguracije, poput korištenja s dvama odvojenim modulima sonde za prošireno pokrivanje ili redundantnost, ili za veće brodove koji zahtijevaju višestruke točke mjerenja za detaljnije podvodno mapiranje. U usporedbi s transduktorima poput Airmar TM150M (600W, stražnja instalacija, samo srednja frekvencija) ili B260 (1kW, fiksna dvostruka frekvencija, ne-CHIRP), B175LM nudi modernost CHIRP-a s diskretnom i učinkovitom prolaznom instalacijom.

« Technical analysis: Raymarine B175 D/T CHIRP 1kW through-hull transducers »

The Raymarine B175 D/T Low-Medium 20° dual through-hull transducer pack is an advanced solution for CHIRP 1kW underwater data acquisition. Integrating two identical transducers into a single pack is particularly relevant for demanding setups. On large vessels or multihulls, this allows optimal transducer positioning for seamless coverage, avoiding potential interference from the keel or other appendages. It is also ideal for installations requiring critical redundancy or powering two independent fishfinder modules, providing increased flexibility for complex navigation and professional fishing systems.

The bronze through-hull installation, while more complex than a transom-mount setup, delivers superior hydrodynamic performance and better protection against turbulence. The 20° hull deadrise angle compensation is a key selection factor: the vessel’s deadrise angle must match this specification (between 16° and 24°) to ensure a perfectly vertical beam and accurate readings. Incorrect installation of this parameter would negate some of the benefits of CHIRP technology. For vessels with a deadrise angle outside this range, other B175 models (0°, 12°, or versions with a fairing block) would be more appropriate.

Technically, the B175LM is a versatile 1 kW option. The combination of low and medium bands provides a strong balance between deep-water penetration and fine target detection in intermediate depths. This differentiates it from single-frequency transducers or CHIRP models exclusively "High-Wide," which excel in shallow waters but lack range. This pack is therefore a strategic choice for captains seeking a robust, high-performance solution adaptable to specific installation requirements.

Frequently Asked Questions

Need help? Contact us

What exactly is included in the Raymarine B175 D/T Low-Medium 20 deg dual-sonde pack?

The pack (reference T70076) includes two identical Raymarine B175 D/T Low-Medium through-hull transducers with a 20-degree tilted element. Each transducer is a 1 kW CHIRP transducer capable of providing depth and temperature data.

What material is the housing of these depth sounders made of?

The housing of each depth sounder is made of robust bronze, ensuring durability and resistance in the marine environment.

What is the purpose of the 20-degree tilt of the ceramic element in the depth sounder?

The ceramic element tilted at 20 degrees is designed to compensate for the hull angle of vessels. It ensures that the depth sounder's beam is directed vertically toward the seabed, even if the boat's deadrise angle is between 16 and 24 degrees, thus guaranteeing accurate and optimal readings.

For which type of hull are these through-hull transducers suitable?

These through-hull transducers are designed to be installed through the vessel's hull. They are particularly suitable for hulls with a deadrise angle (keel angle) between 16 and 24 degrees, thanks to their 20-degree tilted element that compensates for this angle.

With which Raymarine systems are these B175LM transducers compatible?

These transducers are compatible with Raymarine CHIRP sonar systems. They integrate with the CP470 and CP570 sounder modules, as well as with the Axiom and Element Pro multifunction displays.

What is the performance difference between the B175LM transducer and a B75 series transducer?

The B175LM transducer delivers 1 kW of power, providing superior target resolution and better echo separation compared to conventional 600 W transducers, such as those in the B75 series. It is designed for applications requiring higher power and deeper penetration capability.

What are the optimal water depths for low and medium frequency bands?

The low-frequency band (40–60 kHz) is optimized for deep-water penetration. The medium-frequency band (80–130 kHz) is ideal for detailed fish and structure detection in intermediate depths.
