I recently bought a 66sr. The 66sr is one of Garmin’s most accurate units as it locks onto multiple satellite systems - as opposed to just locking on to one system like most units.
I bought it because, 1. My Satmap Active 10 which I bought in 2010 had finally given up the ghost. 2. Satmap units weren’t available, and its looking like they probably won’t be again. 3. The Garmin 66sr was available. 4. I hate touch screens.
Things I like about it,
The overall size, it fits easily in my pocket.
Build quality is excellent – much better than Satmap
Accuracy – it is super accurate. Can stash my bag or hide my bike and tag and find again with confidence
It boots up and locks on very quick.
The screen is very easy to read in bright sun light
Big built-in battery
Things I don’t like,
The screen is tiny, even compared to my ancient 2010 Satmap
It is not very intuitive to use, that and the bloat ware (endless features) make it initially very frustrating to use – but you soon start getting used to it.
It will only hold 200 routes in one folder. It lists them in order of nearest first. I had well over 400 routes on my Satmap logically organised in multiple folders. This is one thing about the Garmin that will drive me nuts.
The price. Very expensive, and particularly so if you buy it with 1,25000 maps, which you’ll want if accuracy is your priority.
Miss my Satmap big time, but I’ll adapt to the Garmin, and hopefully I should get many years use out of it.
Lots of info and youtube videos etc on GPS Training web site.
