![]() ![]() Nasa Marine also provide a Clipper Duet option which comes with a through-hull transducer, enabling speed and depth measurements. The supplied in hull depth transducer wires directly into the display head, offering a no-nonsense, easy to fit depth option without many bells and whistles. The Clipper Depth looks somewhat dated, but the digits are very large and easy to read from a distance, which is more important than having a fancy trim. Whilst they might not be the flashiest instruments, they do a pretty good job and are available as stand-alone analogue devices for a very reasonable price. As such, NASA’s Clipper range is well known by now and trusted and is a particular favourite of small-to-medium-size boat owners. Nasa has built a solid reputation for building marine electronics that work well, are affordable and simple to use. This doesn’t affect our editorial independence. Digital signal processing inside the housing provides depth, speed, and temperature data to a chartplotter, radar screen, or digital display such as the i50.īuy Raymarine i50 Depth kit on Amazon (UK)īuy Raymarine i50 Tridata kit on Amazon (UK)īuy Raymarine i50 Tridata kit on eBay Note: We may earn a commission when you buy through links on our site, at no extra cost to you. The D800 is a Smart multisensor by Airmar – supplier of the majority of depth transducers on the market – that offers depth, speed, and temperature functions in one thru-hull fitting. To fully take advantage of the display, you would want to consider a depth and speed transducer sold alongside the display as a kit. These would be the transducers most likely to go with the i50 depth display as a standalone depth sounder. Raymarine does offer an in hull transducer (the P79) and a range of options for through hull depth alone the best of the bunch if you are looking for standalone depth would be the P19. In terms of the transducers on offer from Raymarine there are several to choose from. This has fast become one of the most popular depth sounder display units on the market. This display is offers low power consumption, has a good red lighting for visibility in the dark and is easy to install. ![]() The screen features excellent viewing angles for both day and night conditions and simple, push-button controls make i50 instruments easy to see and use. The i50 depth offers only a depth readout, while the i50 Tridata display offers speed and depth, while a measure log tracks distance sailed. ![]() The i50 comes in a number of different options. The Raymarine i50 instruments are designed to complement Raymarine’s latest generation multifunction displays. Best depth sounders available right now Raymarine i50 depth sounder The only difference between so-called ‘analogue’ and ‘digital’ transducers is that, in the latter, the signal is sent out as data over a NMEA interface. The time the ping takes to travel down and return is a measure of the distance to the seabed. If you fit a dual speed/depth transducer, or another type of through hull transducer, it will need to be mounted through a 50mm diameter hole in the hull.ĭepth transducers transmit sound pulses or ‘pings’ that bounce back on hitting the seabed. The tube contains some oil beneath the transducer itself which allows good sound transmission through the hull. These are mounted in a plastic tube and is fitted vertically to the inside of the hull. When fitting a stand-alone depth sounder it sometimes comes with an in-hull transducer. However, to get a depth reading you will need to fit a transducer into your boat. The display itself is reasonably simple and the key concern is ease of use as well as brightness of the display and backlight functions. The trend in recent years is towards boats running the vast majority of boat data through a chartplotter or Multi Function Display (MFD) but most of the best depth sounder models still come with a separate specific LCD display screen. ![]()
