Garmin echoMAP 70s Review

Garmin echoMAP 70s has an average rating of 4 out of 5 based on 4 user reviews.



The Garmin echoMAP 70s is a combination high performance chartplotter and fishfinder. The ultrafast updates make this unit ideal for shallow and inland water on any center console or bass boat.

The echoMAP 70s has a seven inch WVGA touchscreen display. The display is crystal clear, allows great visibility in the daytime as well as nighttime, a highlighted user friendly interface that any angler can navigate, and provides crystal clear target separation. Garmin echoMap70s compares favorably to other 7 inch display fishfinders such as Humminbird 858c.

Anglers have the capability of refreshing heading and position as many as ten times each second with the integration of a 10Hz GPS/GLONASS receiver on the echoMAP 70s. This provides considerably better accuracy when the angler is navigating and marking waypoints and permits the echoMAP 70s fishfinder to display a fluid and constant location on the screen.

The echoMAP 70s also allows for sonar recording in conjunction with the GPS receiver. This allows the vessel to coordinate the timing of the return of the sonar relative to the position of the boat by using this feature. This permits all of the independent 5000 waypoints that are user defined to be precise and accurate. The echoMAP 70s is a great tool for the angler for pinpointing and locating the next hot fishing location.

echoMAP 70s fishfinder transmits a 77/200 kHz signal from a dual beam transducer. This device provides fishermen the opportunity to access and connect to marine specific Garmin applications via tablet PC or smartphone with the capability of wireless connectivity.

The Garmin echoMAP 70s tracks boat’s position and displays position data from a VHF radio that is DSC capable. The unit has a water sensor, water temperature log and graph, real time display of fish passing through transducer beam, and will measure depth of underwater objects. This fishfinder also maximizes targets while minimizing clutter, has a Fish Symbol Identification that will help identify fish targets, audible alarms, tide tables, and sun and moon information. The track log offers anglers 50 saved tracks and as many as 5,000 track points. The unit also provides anglers with split screen zoom and split screen sonar/GPS. The echoMAP 70s comes with documentation, bezel, protective cover, flush mount kit, knobs and ball mount, and a sonar/data/power or data/power cable.

This is a very good fishfinder. It does what is advertised very well and the price is much lower than other models with this screen size and touchscreen. The screen is by far it’s best attribute, the display clarity is much better than that of comparable models such as Lowrance HDS 7 TouchInsight. My biggest problem with this unit is transducer compatibility. You can’t connect it to older Garmin transducers because it uses different frequencies. I don’t think this was a good strategy for Garmin, maybe they did that to sell new transducers. If you want to buy a unit with a new transducer this is a good model, if you want to replace the display and keep old transducer you’ll have to buy a different one.

If you’re looking for a fast and accurate GPS this unit is great choice. I fish in the marshes so I need something that will help me navigate through a difficult environment. Touch screen is great, the unit is very easy to operate.

Garmin delivered again with this model. I run saltwater fishing tours in Texas so I needed good GPS. I’m more than satisfied. The chartplotter in this unit allows you to very easily set tracks and waypoints, it even automatically adjusts it to your boat’s position.

I have had a 70s for 3 years now.
A functional unit, for sure, never let me down.
But the aftermarket mapping is poor.
I purchased blue chart to get a better view of Australian lakes, in fact the largest lake in Australia.
But there are NO navigational marks in the lake, no contours and I was less than impressed.
My friends Raymarine mapping makes Garmin blue chart look cheap and nasty.
While the product itself is good and hardy, Garmin need to pick up their act in mapping products.
