+gpsblake Posted September 24, 2020 Share Posted September 24, 2020 Yes, they've gone back a number this time from 66 to 65 but also have added a 66r series to the line up. I have no idea what new features, if any, this new series from Garmin has. 1 Quote Link to comment
Moun10Bike Posted September 24, 2020 Share Posted September 24, 2020 It looks like the major selling point is ability to pull in additional constellations - now GPS, GLONASS, Galileo, QZSS, and IRNSS. 2 Quote Link to comment

jakewa Posted September 24, 2020 Share Posted September 24, 2020 Would like to know how much that quad helix antenna makes a difference? If it doesn't make a noticeable improvement, then rather buy a smaller, lighter, more compact model. Quote Link to comment

Just my unprofessional opinion, but it seems the 60-66 series of units pulls in satellites closer to the horizon better than say an Oregon, thus, leading to maybe a little bit more accuracy because of better triangulation. Not noticeable for geocaching though, any unit these days is going to get you where you need to be, especially if you account that geocache accuracy also depends on the person who placed the cache. I guess they chose the 65 name because the units look nearly identical to the 64s and probably act similar to the end user, still seems though Garmin is coming with new units to compete with itself. Good for the consumer, maybe we will see a price drop for the 64 series. Edited September 25, 2020 by gpsblake Quote Link to comment
+Mineral2 Posted September 25, 2020 Share Posted September 25, 2020 The 65 appears to be using the same case as the 64 series. It's even advertised to use the mini-USB connection rather than the newer, but already outdated, micro-USB that Garmin is putting on the rest of its current lineup. I'm scratching my head here because the GPSMap lineup got upgraded/new additions twice now since the Oregon was last updated, and usually the Oregon is the line that Garmin releases with brand new features. It was the first to see GLONASS (or was it the eTrex?), the first to have bluetooth, the first to have wifi (Monterra not counting). I'm a little confused as to what Garmin is doing by diversifying this line so much. It's not like everyone who bought a 66s recently is now running out to buy the 66sr. Right? We're not all buying new iPhones every 6 months... 1 Quote Link to comment

capt caper Posted October 4, 2020 Share Posted October 4, 2020 I rarely need to change batteries. Usually it's because I forgot to charge them or didn't have time. In one case I gave mine to my wife who forgot to charge her's. I then used the Garmin pack I carry for backup which wouldn't of worked in her's. 680 vs 66st. The technology has gotten to a good point with rechargables. I would assume Garmin has used a quality product in that system. On a side note I saw a review were he compared the 66st vs 66sr and 65 and 64. He said by going to the 65 you get a larger upgrade and retain the accuracy gains of the new system. And can still have battery changes. Good point by the smaller screen turns me off. I hope the 680 get's a upgrade to the new multi gps system soon actually like these others have.

+miblaa Posted October 21, 2020 Share Posted October 21, 2020 (edited) I just received an email from a vendor introducing the new 65 and 66sr models. I've been waiting for these for a couple of years so I'm pretty excited. The only problem now is, should I wait for a Montana-style model with multi-band, or go for the 66sr? I need reading glasses, so the bigger screen is a big plus. I had a 60CSx before, and one thing I remember about it was that entering text was a pain. And the screen felt tiny. Is it fact that the helix antenna is better than the antenna in, e.g. the Montana (mine is the 650)? I've suspected that my old 60CSx was more accurate than the Montana 650 but I don't have proof. It would be cool if we could organize a geocaching "group buy" of these new models. ...oh hey, I hadn't heard of the Montana 700 series until right now. That, with multi-band, is probably what I want. I guess I have to wait... Edited October 21, 2020 by miblaa added content at bottom Quote Link to comment

I was going to order one, but then the GPSMAP 65/66 seris came out, and the Multi-Band/Multi-GNSS works so well on those that I may never buy another model without those features. So....

+tundrabums Posted October 22, 2020 Share Posted October 22, 2020 It was time to get a new GPS unit so I bought the new MAPGPS 65s. Right out of the box I started having issues. I would load a group of caches and confirm they were indeed in my unit. However, when I turned the unit off and then back on, all of my data disappeared as caches and only to be found as waypoints. The problem is as everyone knows, waypoints lack the usability of caches. I contacted Garmin and the gentleman who was helping me just happened to have his MAPGPS 65s with him. He tried loaded caches onto his unit, checked to see if they were there, and when he powered his unit on/off the same thing happened. I downloaded and sent all the files from my unit to their tech staff. I'll post the results and the solutions here. 1 Quote Link to comment

Or for the devices with a built-in battery, will I have to replace my GPS? I don't see these devices as phones or computers. They're tools that can still work independently of technological advances. In 10 years, will Garmin still be selling replacement batteries? Because in 10 years, I know I can still buy a pack of AA batteries - alkaline or NiMH rechargeable. It's bad enough that my phone lasts maybe 5 years before I'm "forced" to replace it.

+Viajero Perdido Posted December 2, 2020 Share Posted December 2, 2020 There are shops that specialize in replacing phone batteries. If they can crack the nut open (looking at you Apple), they can jam* in a replacement battery of approximately the right size. If anything, Garmins should be easier to open than a typical phone. (* I opened a camping lantern to find a soft lithium battery pack inside. The corners were folded back, and the whole thing had a jammed-in look. Until then I never knew batteries could be bent/folded/stuffed like that.) 1 Quote Link to comment

Am I missing something? That path is for the Multi-GNSS feature, which refers to the devices ability to use Multiple GNSS (Global Navigation Satellite Systems) simultaneously. Where all previous models were limited to either GPS only, GPS + GLONASS, or GPS + Galileo, the new 'Multi-GNSS' models can use GPS + GLONASS + Galileo + NavIC + QZSS simultaneously. For those who are not keeping track, that is one or two satellite systems on the older models, and five satellite systems on the new models. But it doesn't stop there. Just below the link for 'Multi-GNSS' you referenced above is another link for 'Multi-BAND'. The Multi-BAND feature refers to the newer models ability to use multiple signals from each satellite on different frequency bands. Traditionally, all consumer grade GPSr have used the 'L1' band. As the 'Multi-BAND' link at the page referenced above explains: Quote Multi-Band Advantages GNSS Signals All GNSS signals include these essential components: Pseudorandom Noise Code (PRN) - Identifies the satellite transmitting the signal. Almanac - Coarse orbital parameters for all satellites in the constellation (updates every six days). Ephemeris - Precise orbital and clock correction data specific to the transmitting satellite (updates every two hours). Modern satellite signals (L5/E5a) may also contain additional optional elements providing: Reduced cross-correlation and interference. Improved data synchronization. Multipath mitigation. L5/E5a vs L1/E1 When used in combination with L1/E1 signals, L5/E5a signals can provide: Improved accuracy via ionospheric correction (WAAS/EGNOS no longer required). Superior multipath recognition and correction capabilities. Enhanced robustness via signal redundancy. L5/E5a signals exhibit superior detection characteristics over L1/E1 signals due to: Higher signal transmission power level (-3.6dB). Better signal to noise ratio (SNR). Greater bandwidth. The L5/E5a frequency band is internationally recognized and protected. If you also open the link referenced above and navigate to 'Pages > Satellite' you can see examples for all GPS configurations, including an example where the GPSr indicates a positional accuracy error estimated at 6 feet, or 1.8 meters. This is roughly the distance between your head and toes. 4 hours ago, Hynz said: What I would like to understand is eg if such receiver has contact to say 2 Sats from GPS, 2 Sats from Galileio and 2 Sats from Baidou can a position be calculated or is any improvement dependent on getting the necessary number of Sats (3 or 4) for each system independently. While I have never encountered a scenario where only two GPS satellites were available at any one given time, and I doubt anyone ever will, the combination you provide above is more than enough to calculate the users position, and those coordinates will be even more accurate when Multi-BAND is enabled.
