I bought the Geko 201 as a replacement for my very old Magellen Blazer 12. The difference is night and day.Although both had parallel processing, the Geko picks up signals much faster. From a cold, fresh-out-of-the-box start, it took the Geko less than a minute to figure out where it was. The Blazer 12 took about 10 minutes even when given hints.
The screens are simple and extremely useful. Even with my very bad eyesight, the display was very readable. The buttons make sense, no manual necessary.
A few people have mentioned a "flaw" with the power button. I have carried this Geko around for almost two months, keeping it in my pocket almost every day. The unit has NEVER come on by accident. The power button is recessed and takes a good push to get it going.
As a hiker and backpacker, my power usage might be less demanding than others. I find that the battery lasts about 8-9 hours on battery save mode. This mode even works well in forests. The only time the Geko is kept powered on is if I'm mapping a trail. Otherwise, it is used for waypoints and position checks only.
The lack of displayed maps is irrelevent as I have yet to see a GPS with enough detail to be worth it. I have linked the Geko to DeLorme's Topo 5 with excellent results. Routes, tracks, waypoints can all be moved freely back and forth. This is great for mapping new trails or discovering hard-to-find trailheads. The memory is more than enough, I've never gotten past 12% full after a weekend jaunt.
Of course, the size is amazing. The color is also nice as I can actually find it! This is an excellent buy and a great choice for those who want GPS served up straight, stripped of all the annoying "features" of other units. I just purchased a second 201 for my hiking friend, she loves hers as much as I do!
This would be a good GPS for geocaching except that it has a fatal design/firmware problem with the power switch.If you carry this in your coat or pants pocket, its a sure thing that the unit will power up all by itself, drain the batteries, and leave you high and dry.
I suggested to Garmin that they change the firmware so that if the unit powers itself up and the power button isn't still depressed after 2 seconds, then it powers itself back down. That would at least keep the unit from powering up from a single jostle of the power button like it does right now.
I would not buy this unit until Garmin makes changes to the firmware to fix the power button problem. You will get very frustrated by it as it is right now.
