Jon DeGraw: As usual, Garmin exceeds expectations. The SOS function works perfect, as does the SMS feature. Lightweight and accurate.

Amazon Customer: Das Navi macht was es soll. Ausgepackt nach Norwegen gefahren und es hat top funktioniert. Kann ich nur empfehlen.

James Archer: OK, waited for this to go on sale and jumped on it - did not really need it, but for the lower price < $400, why not. Basically, solid and works well, but I have had to reset it once after it locked up - hold down the power button for 30 seconds, which worked well and unit came back up. Is it as slick as your smart phone with TOPO maps, no, but why rely on one GPS?

Gene C: Previously had inReach Explorer + - great device for emergency comm, light on GPS functions.
The 66i is more GPS than emergency comm, can now be completely off the grid and have navigation, text communications and peace of mind.

Doug Schaefer: Great GPS., easy to use and very easy to get the Inreach account set up. Battery seems excellent at this point but haven’t had it out in the field at this point, tested it over several days without shutting it off and it did great. Recommend the case

Amazon Kunde: Im Bereich vom Handyempfang bracht man so ein Teil wirklich nicht. Erst in der Arktis oder auf dem Himalaya nicht als ein Teil Sinn. Ach ja, für Geo Caching gibt es preisgünstigere Geräte

dogBoy: Sure it does the job, but the interface is so outdated it hurts.
Screen is low resolution, difficult to read even on largest text setting.
I owned it a year, used it a few times but never felt like I knew what it was doing.
I’d get home, look for my tracks and find I had not started tracking. They should make it more obvious when this is on or off.
Nope, just use your cellphone. Starlink’s around the corner and every man and his dog’s gonna have satellite connectivity in the next few years.
This product is just a relic really. Don’t get me wrong, well built, long battery life, feels good in the hand but… meh!

tcp100: This is the first true full-featured GPS navigator with a satellite communicator built in. Realize what you’re buying into, and it’s a fantastic device.

The original InReach devices were ostensibly marginal at being GPS navigators, that being a secondary trait of what they do. That isn’t the case with the 66i. The 66i has all of the top-of-the-line features of Garmin’s best handheld units.

That being said, there has been a lot of talk of the “pros” and “cons” of this device. Let’s go through them one by one.

1. Price: This thing is expensive for a GPS unit, but in my mind it is NOT expensive for what it does. I used to carry a Globalstar satellite phone when going in remote areas. That was a $350 phone with a $60/month plan - and it didn’t do much but make phone calls, and it wasn’t great at that. No location updates, no SMS. Purely for emergencies. Of course, I also carried a $350 eTrex at the same time. For $700 and $60/mo, I got SOME of the features that the 66i gives me in one device - for $600, $25/mo, and LESS WEIGHT, being key. Add in the weather reports (more on that below), location broadcast, and general utility of non-emergency...

Trey R: I am on the fence about this device. It has profound pros and cons. On the plus side I will say that the screen resolution is very good for a device this size. It is well built. The accuracy is not too bad for a device at this price point. ( I would give the unit itself for stars) I highly recommend getting the silicone protective sleeve and screen protectors as protective measures. My main complaints with this device are: you have to install 2 separate Garmin apps to sync your device with your phone and backup and manipulate your way points. Syncing is accomplished through Garmin Connect while all other actions are conducted through Garmin Explorer. I've had significant difficulties getting the GPS to sync with my phone using the Bluetooth. Also maintenance of the connection is not reliable. I will say that when the devices do sink it's very nice because you will get notification of text messages and phone calls on the GPS. If you don't want that I suppose you could just turn off the Bluetooth.( I would give the apps one star) I tried to call customer support once but was on hold for an hour and when I get a person on the line they told me I had called wrong department and put me...
