Sonar feature

Gramin has next-generation CHIRP sonar. CHIRP stands for Compressed High-Intensity Radiated Pulse.

This technology increases the highest detailed commercially available sonar pictures on the ocean by combining advanced computer algorithms with a continuous-sweep broadband scanning transducer.

CHIRP has military-grade technology. SideVu and ClearVu, both based on CHIRP, give photograph-like pictures of both side and front perspectives.

And the distinction is astounding. Gramin uses the ultra-high-resolution sonar system which produces the images with high quality and accuracy.

This ultra-high-resolution sonar makes you differentiate between the baitfish and gamefish just at the glance. Skilled anglers even regularly recognize certain fish species up to 200 feet in depth.

It is an ideal choice for freshwater fishermen as it won’t scan deep enough in saltwater.

But if you need a saltwater fish finder you can use Garmin Echomap Plus 73sv with a 50 kHz capable transducer which increases the maximum depth capability up to 1100 feet in saltwater.

But you would need to buy a transducer separately to use Garmin Echomap Plus 73sv in saltwater. This is specifically designed for freshwater.


Garmin echoMAP Plus 73sv has a built-in GPS module with a 5 Hz GPS receiver. It also has Chartplotter capabilities. Gramin’s position tracking is accurate since it is updated 5 times each second.

Furthermore, it estimates your boat’s speed so you can keep track of whether you’re moving at the proper pace for the bait you’re using so that you don’t have to use the speed sensor as it does a speed calculation job as well.

The Quickdraw Contours tool enables for personalized mapping of any body of water. The Quickdraw community releases additional ultra-detailed maps by the day.

Lakes are likely to have been mapped with up to 1-foot contour accuracy. This allows you to see a lot of undersea detail.

These maps feature arches, beaches, primitive camping, and other points of interest in addition to nearly 17,000 lakes and rivers. LakeVu g3 maps, which include interior waterways, are included with this fish detector. These charts have Shallow Water Shading capability.

This capability allows you to specify baseline depths and see them on the main screen fast. This software creates a contoured map of the lake’s bottom using sonar and GPS data.

The maps you generate can subsequently be kept private or shared with the Quickdraw Community.

NMEA 0183 and NMEA 2000 networking options are available on the Garmin echoMAP Plus 73sv. It also has a built-in wireless connection.

This allows you to sync it with your tablet or phone, access OneChart capabilities, and connect to ActiveCaptain.  And get notifications immediately on your device, among other things.
