Bushnell GPS BackTrack Personal Locator

A nice device, especially for the price.I bought this after I visited a new city, went from the hotel about 10 blocks to get some chips and pop, and on my return I wondered if x was the street I should head back on, or was it further up, or back one, because I hadn't gotten this unit yet.This is a basic GPS unit that doesn't find street addresses, doesn't have a database of roads or restaurants or anything, but is intended for a simpler use. And it does that well, as it saves a location (up to three) and guides you back to that location.You turn it on, takes about 10 seconds to orient itself, and then you press one of three buttons to save this location as location a, b, or c (the unit helps you a bit, as it shows an icon for either car, home, or star, but the naming is arbitrary--I could have saved that hotel's location as the "home" icon, the "car" icon, or the "star" icon for favorite spot.)Then, when you are done wandering away, turn it on and it shows you the direction and distance in yards to the spot you saved, or to one of the other two icons if you ever saved anything to them. Note that the distance is indicated, not just the direction, so you know if you are 10 yards or 1000 yards away from the spot you saved (switches to miles when relevant) as well as which way it is.I used it in a wooded nature park last week and saved the entrance location. No matter where I wandered it showed the direction back to the entrance and how far away it was (I know the geography of the nature park so I knew it was giving me accurate info.) As for accuracy, I used it in my driveway to save a spot, walked 10 yards away, and let it guide me back to the saved spot, with an accuracy of +- 3 yards. Not as accurate when I stood next to the basketball pole because of the magnetism, and you gotta give it 4 seconds or so to orient itself.Its other mode instead of GPS is as a compass, showing you where N is, again after giving it a few seconds to stabilize.Construction appears robust, with a nice strong lanyard to hang around your neck or your wrist, and the unit likely would survive a drop to the ground. It's 3" across, 3/4" thick. Two buttons: one button that turns it on, selects mode (GPS/compass), and selects one of the three icons, the second button that saves the spot, or turns on a backlight. Also works in meters instead of yards. I now have two of these. I have no financial interest in anything I review.

Real GPS technology is a large number of satellites 12,500 miles in orbit sending a very weak time signal for a computer processor to calculate the holders position in space. Most users don't know or understand that the receiver is not getting blasted with 50,000 watts from their favorite rock station ten miles away, or even a cell signal two miles away. Interference from structures will stop the signal, period.I recently purchased a Backtrack as an economical aid for deer hunting and travel cross country. At the price, Brunton and military compasses can't and won't do the same job without a geodesic map and literally days of training - training I've had repeatedly in 22 years in the US Army Reserve. Much of where I hunt has no decent map, and overhead satellite photography is remarkably low quality in these less densely populated areas. If there is any difficulty in the woods, the real issue isn't which way is north, it's the actual distance and heading from a known point.For the price point, the Backtrack works fine. It does not have an extremely fast response time, but given reasonable patience, it will orient you to the compass and let you know what heading and distance you are from the start point. Reasonable is up to two minutes - which is all it needed the first startup. At that point I set the home icon with the extremely simple two button controls.I tested the unit at distances of yards and miles, and found when handled properly like a compass - held parallel to the ground with no motion - it would show equal distances and complementary headings between two points. At about 700 yards it changes to tenths of a mile, and when between home and say, a parking point, you can measure the exact distance between - straight line.When traversing rough terrain with a unscaled pictographic map, such as printed by the conservation department for most areas, it was simple to keep aware of our position on that map and get a basic idea of the scale involved. I felt more secure with the Backtrack telling me my car was 739 yards away at 356 degrees than trusting my memory of which way an old wooded ravine might go. Again, a compass would have only told me which way was north - something I checked using a Silva Ranger model I purchased while in the Infantry school. It can't tell me a distance and heading to a known point unless I literally pace it out and recognize it on an accurately scaled map.As for literally following the arrow, even a compass won't help you make a better decision to avoid the rough patches and get on a trail heading in the general direction. The Backtrack can't do your thinking for you.Will a GPS show you your car's location in a parking lot? Yes, and for the price, it should. But you will have to learn the menus, operation, and still set the start point where you parked it - raining or not. Just put it on the dashboard and wait. When you're done, give it a minute, hold it flat, don't wave it around, and use normal routes. Walking through walls is asking a bit much. The Backtrack will get you there - if you can remember what you drove. At that point, you might try your keyfob.

This little GPS will find your car for you. But you have to turn it on about 5 minutes before you park, while it searches for satellites. Then you "mark" your location. Put it in your pocket when you leave your car. It will turn itself off in a few minutes to conserve the batteries. When you want to find your car, turn it back on. It will have to re-acquire the satellies, then it will point to your car and count down the distance. It is not too accurate with distance, but it will get you there.There are 3 memory slots for locations (marked car, house, and star). It also acts as a compass.
