Tectonicninja Posted April 2, 2011 Share Posted April 2, 2011 Me and my sister have tried three times in one day to find a geocache without a handheld GPS. Is it possible? Quote Link to comment
JoshMillward Posted April 3, 2011 Share Posted April 3, 2011 Ofcourse it's possible! I've fount all 17 of my caches without a GPS device, but it is a lot harder and requires a bit more skill. Quote Link to comment
+StarBrand Posted April 3, 2011 Share Posted April 3, 2011 Some folks have found many thousand using only maps and a compass. In some areas you can find them with just google maps and some searching. Quote Link to comment
+Gitchee-Gummee Posted April 4, 2011 Share Posted April 4, 2011 Sure you can -- it just requires a different method of attack. A lot of ways to git'erdone -- real maps, Google maps, compass, sextant, dead reckoning, and most likely any combination of the above. Urban caching is fairly easy just using Google maps -- better yet with Google Earth. Outlying areas, easier for the most part with good maps and compass. Quote Link to comment
+niraD Posted April 4, 2011 Share Posted April 4, 2011 Yes, it can be done. I've found hundreds of caches using the satellite view of Google Maps. The only thing a GPS receiver does is get you to ground zero, where you can start your search. The question is whether you can identify ground zero. Naturally, your success will depend upon the resolution and calibration of the satellite images in your area. The satellite images for my local area are very high-res, and are at least as accurate as my old yellow eTrex. But I've seen areas where the resolution of the images is 10x worse, or where the calibration is off by 100' or more. Your success will also depend upon your ability to identify landmarks in the images, and to navigate using those landmarks. This is highly variable. Landmarks are easy to identify in many urban/suburban areas, but less so in some rural/wilderness areas. Some people are very good at reading maps and satellite images, but others aren't.

+A & J Tooling Posted April 4, 2011 Share Posted April 4, 2011 I'm new and use no GPS. I have only posted 3 finds because I wait for my kids to go with me to find and log the visits but I've found about 65 between my place of residence and the town I work in. There have been a few that have stumped me but if I can't locate them, my kids never will, so it's no loss. Quote Link to comment
Pup Patrol Posted April 4, 2011 Share Posted April 4, 2011 There have been a few that have stumped me but if I can't locate them, my kids never will, so it's no loss. Could I borrow those kids once in a while? Quote Link to comment

+kwcahart Posted April 5, 2011 Share Posted April 5, 2011 I guess it's just me, but I can't imagine why you would want to do geocaching without a hand held GPS. To me using the GPS is just part of the fun. Quote Link to comment

In some situations, it can be rather challenging, which makes it fun to those of us who enjoy challenges. Quote Link to comment
+stanolli Posted April 5, 2011 Share Posted April 5, 2011 I have a Blackberry, without GPS, but it has Google Maps loaded so I can zoom and scroll the aerial view to match what I am seeing plus I get a live connection to geocaching.com. It's all paperless and I have a built in camera - how much more fun could I have lol. Seriously though I also enjoy the additional challenge of sometimes having to think on my feet and improvise, but I think there are also times when seeing a plan of the whole picture is easier than following a GPS.

+A & J Tooling Posted April 5, 2011 Share Posted April 5, 2011 I look up the GZ on google and try to find it hours later by memory. If the machine tells me where to go, where is the fun in that? Might as well sit on my butt at home and have someone else do all the work. Hey look.....someone followed their gps....True.... Quote Link to comment

Some like the challenge as a GPSr takes a lot out of the challenge (for the most part). Kudos to those successful GPSr-less cachers! Me? -- I've done my time w/o a GPSr, I have and use one now and you ain't takin' it away! Quote Link to comment
sick4x4 Posted April 5, 2011 Share Posted April 5, 2011 My 1st cache was without a GPSr but my 2nd if i followed the map directions had me almost half a block away....kudos to you if you can do without but i dont think im that savvy and couldnt imagine caching without one....i think the urban caches could be done without but when roads arnt mapped im that guy and will get lost lol....have fun Quote Link to comment
Ruzhye Posted April 6, 2011 Share Posted April 6, 2011 I've also used the google maps image to find caches, as well as my GPSr and iPhone. Use whatever you can to find your next cache. Quote Link to comment

Look 30 ft NW of the downed tree. At the other end of the spectrum, here's the best resolution I could find for a cache I found in Costa Rica. As you can see, not is the resolution pretty poor but the entire region is obscured by cloud cover (it's near a cloud forest) Quote Link to comment
+edscott Posted April 8, 2011 Share Posted April 8, 2011 Sure there are bad photos, but with the number of caches out there I can probably still find enough to keep me busy the rest of my life. Regarding the Costa Rica photo, if the road was accurately drawn I'd still go for it, but I suspect that too is someone's general estimate. Quote Link to comment

Guideline are not rules plus I've read the guidelines and have noticed a lot of caches don't always follow them. I'd rather be accurate than have my cache suck because my gps was off. I went on one the other day and the coordinates were off, they were off so much that someone felt the need to add more accurate coordinates in the log (I didn't know they were off that much which screwed my whole hunt up). The coordinates given if accurate would have made it a higher terrain rating than was advertised as well. As long as you're giving accurate data and providing a good hunt, get your info how you want. No one is going to know how you got it any way. Quote Link to comment
+edscott Posted April 9, 2011 Share Posted April 9, 2011 Assuming you have a good aerial photo, and assuming you can read it accurately, you could eliminate some GPS errors, but I'd not want a bunch of people running around placing caches without a GPS. I've seen enough people struggle with map reading and navigation to know I'd rather have them reading numbers off a screen. I'm OK with the occasional coordinates that are off by 20-30 feet.

Maybe you can make a placement as good or better than with a GPSr. But, just so you know, I can also. Was using compass and topo maps two decades before GPS became viable. I still love USGS topo maps. The point of this is... the guidelines DO state that one will utilize a GPSr to obtain the best possible coords for a placement. Should the reviewer discover that you do not, the cache will not be published, or if already published, he/she could very well have it archived. Why? Because you failed to follow the guidelines. Not rules, but the closest thing we got to them, and the reviewers follow them pretty darn closely. Now, you can bend, break or read whatever you want into (or not) the guidelines, but that is what geocaching as we know and utilize it is all about. Argue, whimper, whine and cry all you want. You may be the best orienteer(er) in the world -- your idea is still outside of the guidelines. Quote Link to comment

+nittanycopa Posted April 11, 2011 Share Posted April 11, 2011 If you can place the cache without a GPS and get it within standard accuracy - 10-20 feet (urban), 20-30 foot (rural / wooded area), I'd be impressed.

If your coords are considerably off, though, you bet I'm posting accurate ones in my log should I find your cache. I know lots of people that can do it. My point is that if Geocaching.com would allow it there are lots more that would try it and possibly be off by hundreds of feet. I'd rather go into the woods knowing the spot on my map is within a few feet of the cache, not just on the right hillside. Quote Link to comment

So however many meters are in 20 feet. Just commenting to add that there's no such thing as "spot on". Every reading, every measurement has a certain inaccuracy associated with it. The best coordinates you can get on geocaching.com have an accuracy of around +-3 feet due to rounding errors. But if you manage to get within 20 feet using topo maps only, I'd be impressed. Personally I don't believe it's possible, at least not with the USGS 24k maps. 20 feet would equal 0.01 inches on the map, that's beyond what's being measurable accurately. But whatever, if you feel you wanna give it a shot, go for it and see how it works out. Quote Link to comment

+edscott Posted April 12, 2011 Share Posted April 12, 2011 (edited) When coordinates are off I usually say something like "the photo puts it 60 feet to the east" west ... or whatever.. Often I could say "The aerial photo took me right to the bare spot where everyone starts their search, but the cache is several feet away". Gotta say though that for my first cache find I used a 1:24000 USGS. I found four points on the map that I could identify on an aerial photo with the coordinates marked on that map. (Remember Topozone?) Connecting points 1&3 and 2&4 gave me two crossing lines that were each over a mile long. I marked that crossing on the USGS and found the cache. If I was still using USGS maps instead of today's aerial photos I'd be lucky to find 5 caches a week. Edited April 12, 2011 by edscott Quote Link to comment
+sword fern Posted April 22, 2011 Share Posted April 22, 2011 Well, Before I recieved my first GPS I had found about 6 caches. Once when without the GPS I found a geocache (small) thinking it was a different geocache (micro). I realized my mistake when I tried for the cache i had found but did not know. Caching without a gps is possible, but EXTREMELY HARD. Its practically impossible to find caches in the woods without a GPs. for urban caches, its possible. Quote Link to comment
