To calculate the overall star rating and percentage breakdown by star, we do not use a simple average. Instead, our system considers things like how recent a review is and if the reviewer bought the item on Amazon. It also analyses reviews to verify trustworthiness.
This will be an oddball review. I own four GPS60 units and use them in amateur surveying. I bought them because they do waypoint averaging and accept an external antenna and external power. I leave all four averaging their waypoints for minutes or hours or even days at a time, typically with external antennas (from Garmin or Gilson). When I'm not out surveying I usually leave one or two doing waypoint averaging using a couple of external antennas on my roof. After a few days the estimated accuracy shown on the display is usually down to 0.3 or 0.2 feet, sometimes down to 0.1. I've analyzed months of data collected this way and found that the accuracy estimate is a good estimate of one standard deviation, and most of the measurements are closer to my overall average antenna position than the estimate on the screen. Most of the ones that say "0.1 feet" are closer than one inch to the overall average. Note, though, Garmin's software insists on rounding the coordinates off to lower resolution than this - I have to use mapping software by Fugawi to get enough digits reported in the coordinates. Any product that can report your position to an inch, based on satellites, is pretty impressive - even if you have to leave it running a week! Not sure, but I think all Garmin's 12 channel products, which must be almost all of them, use the same GPS engine. And another reviewer was wrong to say these can't output NMEA data. They can - you just have to menu over to Setup > Interface and select NMEA instead of the proprietary Garmin. I just checked to make sure!
I have two GPS 60's I bought to replace our old and very well liked 48's that have failing memory batteries. I have had them for 10 months now of full time cruising. We've been cruisng for 12 years now.
First the positve. Accurate distance in feet to waypoint, very handy for marking where we drop the anchor and if the anchor has dragged. Handy to know where the anchor is (direction and feet) when the wind dies and a new boat comes in to anchor. Low power drain, we leave them on continuously plugged into 12v. Connection for remote antenna. Small rugged unit. Good price.
Neagatives: Anchor drag alarm single low tone beep is useless, tone and duration NOT adjustable, our old 48's have continous alarms that would wake you. The backlite timer is deactivated when you plug into 12v source (which we always do). I guess they figure this timer is a AA battery power saving feature only, we see it as a night vision saver so the timer should work in all power modes. On/off button difficult to use. No direct numerical entry of waypoints, must make a mark then alter the Lat/Lon. Must use remote antenna for unit to work inside our cabin, we have thick wood/foam/glass constuction. Not a big problem, remote antenna cheap, most GPS's have problem receiving in our cabin. The rounded bottom makes it difficult to stand up for viewing, laying it down hurts antenna reception. Again not a big problem we strap it to a vertical surface when we're not holding it.
One unit has failed to go past the start page no matter what buttons I push, the only way to turn it off is to remove the batteries.
Not happy with them but what other simple, portable, non-color, non-map choices are available, I may try the 72H but I understand it also has the useless anchor drag alarm single beep.
This is a good, but higher level basic GPS. Picks up satelites reasonably well, except in heavier tree cover. Clear and readable display. The unit performs as advertised. What I don't like about it is the 1MB memory limitation. I'm interested in downloading National Park topo maps and the 1MB memory limits me to one quadrant in the typical western US MapSource Western National Parks. If your one day trail spans more than one map grid or if you plan a multiday hike you are out of luck. I'm not a geocacher, so I was looking for the basics -- altitude, direction, track some of my way points. The maps was a nice to have. But once I started playing with them, I liked them and wanted to use them more. That's when I ran into the head room issue. So I upgraded to the GPSMap 60CSx -- more money than I intended to spend, but....
4 Stars because of the memory limitations. If that is not an issue for you, then 4.5 stars.
for the price this is one of the best GPS units ever made. no frills, just simple ability to give you an accurrate location and track your movements. Memory is a bit limited, and accurracy not as good as you can get now, but if you can still find one of these for under $100 and you just want a simple hardworking GPS and don't need a pretty color display, buy one. I used this for fieldwork (taking sample locations, mapping out roads, etc) since 2009, some of the labels coming off the buttons (from riding on the dashboard), but it still works great. It also went for an unplanned swim with me and never stopped functioning.
I have enjoyed this product since the day it was put into my hands. My brother has one and he enjoys it very much and its a great help geting places. I use mine a lot to find geo-treasures and getting from point to point. Its been a great help and would recommend it to anyone who is starting out in geocaching.
I purchased two of these units the first one worked OK. The second one has a problem. In a side by side comparison the signal qualities of the two units vary. I checked there accuracy and tracking with OziExplorer moving map software. The first unit tracks pretty good, but the second units position is off a large percentage of the time and sometimes as much as 400 meters. I sent the faulty unit to Garmin to be repaired. They sent it back with a description of the problem and that it had been fixed. I checked the unit out and it is the same as when I sent it to them. Now I'm stuck with a dud.
