Navigation functions
As the name of the machine suggests, the echoMAP CHIRP 54cv is a chartplotter. Its built with a 5 Hz internal GPS/GLONASS module, which gives positioning and heading updates 5 times per second. The machine also uses the Global positioning system to point the speed of your boat.

The machine comes pre-loaded with the BlueChart g2 HD maps. These cover the U.S. coastal waters and Bahamas, West Coast, East Coast, the U.S. portion of the Great Lakes, and the Gulf coast of florida. The BlueChart g2 chart platform gives a significant smooth transitioning between zoom levels, and excellent continuity across chart boundaries. It includes several functions. They include currents, tidal stations, IALA symbols, and depth contours, basically all information included by NOAA charts. Fishing charts next to the bottom charts have bathymetric contours with less visual clutter. The machine also offers a Safety Shading option, via that you can designate up to 10 different depth ranges, and assign them to the depth contours, so that it is much better to see target depth instantly.

The unit’s charts could be upgraded, this technique being appropriate for LakeVü HD Ultra or BlueChart g2 Vision. Auto Guidance is a function made available from the BlueChart g2 Vision charts. It actually opens other functions for your unit. For instance, it can read through the existent charts so as to create a virtual safe pathway, enabling you to avoid obstacles and obstructions such as for example shallow water, low bridges etc, on your own routes.

This unit can conserve to 5,000 waypoints, and 100 routes. In addition, it includes a trail recording function, letting you save 50,000 track points or more to 50 tracks. Evidently, you can convert tracks into routes, add waypoints to them and retrace them.

This unit offers the Quickdraw Contours function. This function is comparable to the AutoChart Live function made available from a few of the Humminbird units, such as for example HELIX 5 CHIRP SI GPS G2, for instance. As its name suggests, it offers you the probability to include depth contours to your maps as you navigate, predicated on the sonar readings. Thus, whatever charts you utilize in your unit, there won’t be any corners of your selected lake uncharted.

Sonar and transducer
The Garmin echoMAP CHIRP 54cv 010-01799-01 includes the GT23M-TM (4-pin) transducer. This transducer includes a transom mount. In addition, it includes a built-in temperature sensor and has 30′ of cable.
This Garmin fish finder is with the capacity of using multiple frequencies. Put simply, it could use 50/77/200 kHz frequencies for 2D and 260/455/800 kHz for ClearVü. Evidently, as its name suggests, it’s a CHIRP unit and will modulate the sonar pulse over a variety of frequencies. Thus, the images have less clutter and there’s better separation between fish targets. For instance, if the transducer beam hits several several larger fish that are close together, there’s an increased chance to see their individual arches on screen, instead of just a major dot of color, which might be recognised incorrectly as a structure, particularly if it’s near to underneath.

The GT23-TM is a mid-band CHIRP transducer. Therefore, with it the machine may use a CHIRP pulse modulation between 80-160 kHz for 2D, and 245-275 kHz or 455-465 kHz for ClearVü. For 2D, the transducer uses conical-shaped beams, at angles between 24°/13°. For ClearVü, the beams are fore to aft, but wider laterally, 51° for 260 (245-275) kHz, and respectively 32° for 455 (445-465) kHz.

The unit’s maximum depth capability is 2,300 ft (701 m). But with the supplied transducer, the machine can reach only one 1,800 ft (548 m) in 2D, and 1,000 ft (305 m) in ClearVü. Also, the recommended vessel speed for crisp-clear images is up to 6 MPH. The transducer provides a bottom reading at boosts to 25-30 MPH, however in general, the bigger the speed, the low the standard of the returns.

There are lots of sonar-related functions that unit provides. Included in this, we are able to number Split-Zoom, Split-Frequency, Sonar Recording and Sonar Rewind, Circular Flasher, Bottom Lock, Data Graphs, and more.

Control unit features and functions
As its name suggests, the echoMAP CHIRP 54cv is probably the Garmin fish finders built with a 5-inch display. It includes a square display, WQVGA, with a 480 x 480 pixel matrix. There are several image combos available, but instead of other models, you can only just reap the benefits of two-panel views. Basically, you can tend to view your charts and ClearVü, 2D and Cv in split-screen etc.

This echoMAP unit is IPX7 waterproof, this means its cables are secured pretty tight in to the unit, the screen is sealed well, and the machine can basically withstand rain, splashes, and even immersions, up to at least one 1 meter in freshwater.

All unit’s cables plug in to the mount, as the unit plugs in to the mount with a multiple pin connector. There’s also an NMEA 0183 from the mount, however the package also contains an NMEA 2000 adapter cable (4-pin female, to 5-pin male) aswell, so you should manage to integrate this unit without much hassle into your boat’s grid, if you are using NMEA 2000.

Given the bond system, the unit can certainly be disconnected from the mount, if necessary. The mount is a straightforward, tilt-swivel type. However, the box also contains a flush mount.

The transducer connector features 4-pin. Thus, just in case you want to use another one, which posseses an 8-pin connector, you will need to use an adapter, which can be included.

This unit will not feature wireless connectivity, but data could be transferred via cable, or via microSD card. The microSD card reader features one slot. In terms of data transfer, you can playback the sonar recordings on a computer using the HomePort application. Also, you can share the maps you’ve made up of Quickdraw Contours on Garmin Connect.

Finally, the box also contains a unit cover.

The Cons
Manual isn’t specific to the machine, but to the complete group of echoMAP CHIRP units (at least for the present time). So, you’ll need to sort of choose the information linked to this particular unit.
Summary
The Garmin echoMAP CHIRP 54cv is a fish finder and chartplotter unit, offering powerful CHIRP 2D and ClearVü sonar, with superior depth capacities and clearer imaging. It’s built with an easy and accurate internal GPS and the united states coastal BlueChart g2 HD charts pack, thus it’s something designed for off-shore fishing. However, because it also offers the QuickDraw Contours application you can basically map any body of water, revealing the most up-to-date depth contours. It’s not specifically an inexpensive unit, but given the actual fact that it includes a fairly expensive transducer, and will be offering a constant selection of navigation and fish finding features, it’s safe to state that the system includes a decent price/value ratio.
