I've been an eTrex user for literally decades: I bought the original eTrex shortly after it was released in 2003, and an eTrex 20 (shown in orange in the photo) shortly after it was released in 2011. Without fail, they've been solid, reliable, and long-lasting units that have served me well after miles on the trail, off-road, and all over the world even in the harshest environments ranging from the peaks of the Swiss alps to the sandy deserts of Oman.The eTrex 22x (blue in the photo) is no different. Almost literally, for better or worse.The 22x is virtually identical to the 20 in all respects, except that it comes with some additional internal storage (which is irrelevant if one uses a microSD card) and the Garmin TopoActive maps. Other than those changes, it appears to be literally the same unit.In most respects, that's excellent: the eTrex 20 that I'm replacing (after the flexible rubber over the buttons finally wore out and rendered it not waterproof and unusable) has been an outstanding unit and it's good to replace it with something similarly robust and easy to use. The user interfaces for both the 22x and 20 are simple, easy to understand, and easily operated with the side buttons and joystick. The receivers in both are sufficiently sensitive to work even with tree cover and in foul weather, and receives signals strongly even if the unit is sideways or upside-down. Both are IPX7 waterproof, have a rated battery life of 25 hours, have a 2.2" color screen, weigh 5 oz (141.7 g), have the same mounting rail on the back, and are still made by Garmin in their factory in Taiwan (though the USB cable is made in Taiwan or China).I particularly like that the 22x continues to use AA batteries rather than a non-replaceable rechargeable battery (often seen in other more modern receivers) since AA batteries are available virtually anywhere on earth. It's ability to to set the battery type in the menu (alkaline, non-rechargeable lithium, or rechargeable NiMH) is very useful for ensuring the battery gauge is accurate.While the 22x retains all the excellent features of the 20, many aspects of it show its age: it has the same L1-only GPS+GLONASS+WAAS/EGNOS receiver as the 20 (no L1/L2/L5 multiband receiver, nor any support for other constellations like Galileo or Beidou like other more modern Garmin receivers), the same screen, the same user interface, etc. The color screen is acceptably visible in bright light, but advancements in screen technology make newer, higher-contrast screens seen in other devices even better.The 22x still uses a miniUSB port under the rubber flap on the back; while the port is robust and durable, having something more modern like USB-C would have been nice. Finding a miniUSB cable in shops is becoming more challenging these days, now that microUSB and (more recently) USB-C have superseded it.Other than the microSD card and the USB port, it lacks any sort of external connectivity -- it would be nice if it had Bluetooth or some other means of connecting to a smartphone or computer to receive software and map updates, update Geocaches, sync waypoints and tracks, etc. Having a built-in NiMH battery charger that could charge NiMH batteries when plugged into USB for power would be convenient and eliminate the need to carry a separate battery charger.Don't get me wrong: the eTrex 22x is a fantastic receiver and will give you many years of faithful service in even the harshest conditions, but even though it was released in 2019 it's fundamentally the same as the eTrex 20 which came out in 2011, which in turn is very similar to the original eTrex from 2003. It's robust, reliable, and durable, but it's beginning to feel a bit dated compared to some of their more modern receivers and lacks some of the quality-of-life features that more modern receivers have.If you don't need or care for those modern bells and whistles, this is an outstanding receiver.
