Overview
No1 - Currently Garmin's best selling GPS unit - Garmin GPSMAP 66sr
Includes free Gold Support Package
- GPS Training review on the Garmin GPSMAP 66sr - the expert's view -
Since the launch of the Garmin GPSMAP 66sr in late 2020 it quickly rose to the best selling Outdoor GPS unit and rightly so.
The case looks very similar to the Garmin GPSMAP 66s, but the key updates on this previous model are -
- the built-in battery, with a stunning 36 hours of battery life. I have always been very skeptical of Garmin's official figures but it actually is doing this
- multi-band satellite signal giving great accuracy, the next generation of GPS technology.
- built-in European mapping (look at FAQ's tab to see video of these).
Therefore if you are a four-season walker i.e. you need a buttoned GPS unit as in winter you will be wearing gloves, you need to look no further.
Overview of the Garmin GPSMAP 66sr
Multi-band/GNSS handheld with sensors and TopoActive Europe maps.

- Built-in battery

FAQ'S
1. What are each of the map options available with the Garmin GPSMAP 66sr?
This unit has Topoactive mapping on the internal memory and so this option comes as standard with any option you purchase. (Eg, if you purchase TOPO Great Britain Pro 1:50k, you will also get Topoactive mapping on the internal memory)
– Garmin GPSMAP 66sr With Western Europe TOPO ACTIVE Mapping
Garmin TOPO ACTIVE mapping is a proper digital map, as you zoom in you get more information and as you zoom out you get less. BUT, it is not an Ordnance Survey map, therefore it does not differentiate between Bridleways and Footpaths, it just marks them as paths.
It covers 47 European countries, compiled using the community-generated OpenStreetMap (OSM) database. Coverage for: Albania, Andorra, Austria, Belarus, Belgium, Bosnia-Herzegovina, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Kosovo, Latvia, Liechtenstein, Lithuania, Luxembourg, Macedonia, Malta, Moldova, Monaco, Montenegro, Netherlands, Norway, Poland, Portugal, Romania, Russia (Kaliningrad only), San Marino, Serbia, Slovakia, Slovenia, Spain, Sweden, Switzerland, Turkey, Ukraine, United Kingdom and the Vatican City.
– Garmin GPSMAP 66sr with TOPO Great Britain Pro 1:50k (2021 edition - most recent)
This is full GB at 1:50k mapping on a map card, which sits in the back of the GPS unit.
The TOPO PRO means that it is the latest map card from Garmin, giving you off road turn by turn routing within the National Parks, this means you can select a location many miles ahead and the GPS will route you via the footpaths to get to that location (like a car sat nav does).
Outside National Parks the GPS will navigate you in a straight line from waypoint to waypoint.
Don’t worry, here at the GPS Training we set the unit up for you so you can easily use these features and we even include a quick start guide so you can quickly get up and running with your GPS unit.
