It don’t mean a thing if ain’t got that ping. With apologies to the first lady of song, the late great Ella Fitzgerald, that sums up fish-finder performance. The world’s finest sonar is useless ...

An in-hull (aka shoot-through) transducer mounts to the inside of the hull and transmits and receives sonar signals through fiberglass, eliminating the need for drilling holes in the hull. This also ...

Here’s a number you might not believe: 30. That’s the number of chirp transducers offered by Airmar, the single largest maker of sonar transducers for recreational marine use. While Airmar was once ...

So you’ve dusted off the old fishing rods, launched your boat, and cast a couple of dozen lines only to find yourself coming home empty-handed. While fishing requires patience, anglers use many tools ...

The I Beam VT-300 Transducer is very compact. Its design resembles a train track or sectional piece of steel, thus the name I Beam. The VT-300 transducer features push-style binding posts that can ...

[Lindsay] has a wonderful writeup about a new toy in the shop, an ultrasonic transducer. The 28kHz, 70W bolt-clamped Langevin transducer by itself is not much use, you need a power supply, a horn to ...

Quantum technologies, which leverage quantum mechanical effects to process information, could outperform their classical counterparts in some complex and advanced tasks. The development and real-world ...

A new theory of how the brain works — neural transduction theory — might upend everything we know about consciousness and the universe itself. Let’s start with my 95-year-old mom. Her memory is ...

There have been many different ideas presented for increasing the acoustic output of a piezo buzzer or ultrasonic transducer. Most of them involve rather complicated circuitry that drives up the total ...

Quantum transducer A niobium microwave LC resonator (silver) is capacitively coupled to two hybridized lithium niobate racetrack resonators in a paperclip geometry (black) to exchange energy between ...
