+J Grouchy Posted February 28, 2020 Share Posted February 28, 2020 I use my phone almost exclusively. I've really tried to make my Garmin more useful, but the interface is just awful, the display is substandard (compared to what I'm used to with my smartphone) and I've found the accuracy to be pretty much equivalent in most circumstances. The few times I used my etrex, it was on a long hike or in rainy weather or when I was in a location without a reliable 4G signal. 1 Quote Link to comment

You don't need a 4G signal at all to use your phone's GPS, much less a reliable one. You DO need 4G or WiFi for online maps, but if you preload maps, much like you would on a GPSr, you can get around that problem as well. $20-$30/yr will get you high quality Gaia maps for a year. 1 Quote Link to comment

The leaders in their fields, as best as I can tell. Between the two, fully offline caching is definitely available on phones, just like it is on classic GPS units ... with the advantage of being able to go online for quick updates if you feel the urge.

Recently relocated to Silicon Valley and there are some amazing parks and trails in the hills around here. The problem no cell service. So I have two lists of caches in different parks that I have saved for off line use. I update the list before I leave or along the way in case there are issues with the caches or get the latest hints. As others have said the gps function still works fine and the listings can be read. The one downside is that I miss new cache placements but one park appears to be pretty saturated already. Quote Link to comment

+Wet Pancake Touring Club Posted March 2, 2020 Share Posted March 2, 2020 J Grouchy mentioned that the GPSr they use is sub-standard compared to their smartphone. For me, it's the exact opposite. The trans-reflective screens on my GPSr's are readable in direct sunlight. I cannot see my smartphone display without turning my back to the sun, and creating a shadow. As for accuracy, each device has their own little quirks. Generally, my Montana is OK, but the Oregon does better in trees. They both have multi-pathing issues downtown in large cities. The smartphone is usually better downtown, because of its ability to use WiFI and Bluetooth enhancements, however that backfires in large downtown parks. My take-away, smartphone versus GPSr, it depends on a lot of different factors. YMMV. 1 Quote Link to comment

There isn't an objective generic "better" or "worse" - the comparison needs qualification. And when that happens, the one that's better for you will only be determined by you. Because "you" is one of the biggest factors Quote Link to comment

I prefer both. I use "Waze" to route me to a cache area (or to hunt for a parking place for individual caches), and it cannot be pre-loaded, so it works only in an online phone and fails miserably at times. So my toughest challenge is mitigating the problems when the phone Apps fail... preparing in case they fail... in case there's a bug this month that has broken some App function. I have an old Garmin Nuvi ready to route me home, just in case. So it's more like both, plus a backup. But I have a Garmin Oregon 750. The phone can talk to it. So that setup is fluid. It's one or the other or a combination of phone and GPS. The deciding factor is just how solid, or how borderline, or how gone, the data signal is. Which you don't always know in advance.

I'm caught off-guard frequently by "no service", like in the middle of town where I've been caching online all day (OK, it's not in Silicon Valley, but still ). Now I have to change settings on my phone (probably find an emergency Hotspot), switch my brain to "OK, I'm totally offline now, so remember there's that "drafts" glitch, and don't use that button or that one or that one" ...when I was fully prepared only to work online like 99.9% of "phone cachers" expect to do. So then my problem is "you're using Verizon, right?". Nope. "Because that's your problem, you're not using Verizon". So I need just the right current model of phone and Verizon. Got it. I wonder why that wasn't mentioned before. People could go ahead and tell me up-front what exactly all the "phone" requirements are, not wait til it fails and then mention another thing I need. On balance, the handheld GPS has the advantage "offline", so I close the Apps and use the Garmin. Edited March 2, 2020 by kunarion Quote Link to comment

Keystone Posted March 3, 2020 Share Posted March 3, 2020 OK, we've established that "availability of cell service vs. needing to plan ahead by saving cache data" is a relevant consideration when deciding between a smartphone and a handheld GPS. Let's keep on topic, thanks. Quote Link to comment

There is a company that is producing a new mass market GPS chip that can be put into a phone that alledgedly will be accurate to within one foot. https://www.theverge.com/circuitbreaker/2017/9/25/16362296/gps-accuracy-improving-one-foot-broadcom That's an old article whose prediction didn't come true. However, it is worth noting what technology is actually in the works, and when... I believe that article refers to access to the L5 band, a topic we've already covered elsewhere, and for which some phones are already fully prepared. Don't expect 1 foot accuracy, however. The addition of L5 will certainly improve things (think of worldwide WAAS and EGNOS, but better), but not to that degree. It will be a bit until the full constellation of current generation satellites is up in the sky and the requisite messaging to get turned on to get the best benefit.

I see many Forum Threads about online and offline bugs by people who in fact pre-load the data, so not only is “pre-loading” not the entire answer, but, yes many people are using phones with the expectation of being online. So it is how you use it, but also that there are a ton of gotchas in any case. But if you work entirely offline, what exactly is a “phone” for? If it's simply the convenience of one device (a phone), you already have a phone. You don't need to ask “GPS or phone”, you have a phone already. Why not then enjoy the phone? Maybe because a phone is... not so great for Geocaching? Hold that thought. And if the question is “I have neither, so do I run out and buy a top-of-the-line phone that costs (in addition to a monthly data fee... or are you using it without data?) twice as much as a top-of-the-line handheld GPS?”, I'm not gonna recommend a phone to you in that case. Anyway, the OP owns newish phones, and now a Garmin Oregon 700. So it's still maybe about ""Phone vs. Garmin", but more a matter of putting it all together.

That’s a lot like what I did for a few years. I had “phones” (also an iPad) with no phone subscription, loaded with caches, which I might use to find a cache, but more as a database backup. And an easy way to load a new cache on a trip. It’s not too different now that I have data service. But deciding “GPS or phone” really depends on the particular GPS and Phone. And the cacher’s situation. 1 Quote Link to comment
+HoochDog Posted March 12, 2020 Share Posted March 12, 2020 Just thought I'd add something interesting about "1 foot accuracy" I've recently done some caches involving Celestial Navigation and was curious about how far a degree/minute/second is. 1 minute of latitude is equal to 1 mile 1 mile is 5280 feet Geocache coordinates are listed out to the 1/1000 place of a minute. 1/1000 * 5280 = 5.3 feet. So it's really only possible to have accuracy within 5 or 6 feet, unless you have geocache coordinates out to more decimal places. 1 1 1 Quote Link to comment
+ecanderson Posted March 13, 2020 Share Posted March 13, 2020 True enough, which is why when I see coordinates for consumer use posted out to 6 or more decimal places (dd.dddddd...) in any venue, I can only chuckle at the waste of bits. Here, 0.001 in decimal minutes is roughly 4' 'wide' and 6' 'tall' on the map. The width (longitude) depends upon your latitude, of course. 1 Quote Link to comment

To be precise, 1 minute of latitude is equal to 1 nautical mile, which is 1.1508 of your statute miles. But the GPS technology is only accurate to a few metres (about 10 feet) under ideal conditions so increasing the number of decimal places in the minutes beyond 3 won't make it any more accurate. 3 Quote Link to comment

As I noted, in decimal degrees, 6+ is where it gets a little silly. Note that for decimal minutes, I used 0.001 as the reasonable limit. The new Garmin units that display to 0.0001 decimal minutes are a little overkill, but that has been covered in another thread. 1 Quote Link to comment

However, we can map to a much higher degree of precision, so having coordinates to more than 3 decimals can aid in visually locating more precise locations, even if a gps device can't pinpoint a location physically to that precision. The GPS data can be extra precise, while the GPS device is limited along with our standard GPS coordinate format (in geocaching) of 3 decimal minutes. Someone with a much higher precision device could provide a more accurate location - though it would be reduced once made into a listing. The CO could provide more accurate coordinates in the description for anyone who has a device with higher accuracy than the 3 decimal digits provides. 1 Quote Link to comment
