Garmin Alpha and Astro GPS Units

 

Much improved

Although often used as a tracking and training aid for working dogs, the Garmin Alpha 100 is also ideal for anyone whose much loved pet pooch likes to go a-wandering! It is a much improved and updated version of Garmin’s Astro 220 &320 GPS units and has many features that its predecessors didn’t have!

How do they compare?

In this Garmin Alpha 100 and Astro 220 Comparison Review we’ll see just how much of an advance it really is. So let’s take a side by side look at the two generations of these amazing devices Garmin dog tracking handheld GPS navigation devices.  The older Astro series represented in this video by the Astro 220 and the brand new Alpha 100.

Appearance

Let’s start with the physical appearance. The physical dimensions of both units are almost the same with Alpha just 0.1 inch wider and thicker than the Astro series devices. Both units have a GPS antenna and removable VHF antenna. The most obvious difference is that instead of physical buttons and the Astro series alpha uses touch screen controls. The only physical buttons on the Alpha are the power button on the side and Three Dog Training buttons above the screen.

Tri-Tronics

This is another major difference between these products while the Astro series were just able to track the dogs but did not have the means of communicating with them, Alpha units
incorporate Tri-Tronic solutions that allows owners to both train their dogs and also send remote commands using 18 levels of continuous or momentary stimulation or an audible tone command.

Display

The Astro 220 is a discontinued model and it has the 256 color TFT screen. The top-of-the-line Astro 320, just like the new Alpha, has a 65,000 color transflective TFT display, but Alpha’s display is larger with 3 inch diagonal versus 2.6 on astro the units. The units weigh almost the same, about nine ounces each so won’t weigh you down much on long trips out.

Batteries

Astro runs on two AA batteries or rechargeable Lithium or NIckel Metal Hydride batteries. Alpha only runs a rechargeable lithium-ion battery. The battery life on both units stated at about 20 hours and both units have micro SD slot behind the batteries and have a USB port.

Memory

The Astro 320 has 1.7 gigabyte internal built-in memory but Alpha comes with 4 gigabyte. However much of it is used by preloaded TOPO maps leaving only 500 megabytes for user storage. Astro series does not have TOPO maps preloaded.

Extra Features on the Garmin Alpha 100

Alpha also supports tracking up to 20 dogs or your buddie’s other Alpha devices, compared with 10 dogs maximum for Astro. Both units support automatic routing as well as wireless data sharing, photo navigation and have a barometric altimeter and a compass.

More Powerful

As you can see the main difference is Alpha has Tri-Tronic functionality for dog training and control, touch screen controls and beefed-up specs, the ability to store more data and communicate with more devices.

Looks like a really useful tool, especially if you have working dogs. My dogs stay at home mostly so they do not need this level of tracking but it is good to know that this type of technology exists if I need it in the future.
