Leica ATX1230 GPS SmartAntenna. This is rugged, shock-proof, water-proof, dust-proof just like the Leica GS09 is. Dropping it or working in the rain does not bother it in any way. Actually, it is immersible and can stand shocks one has no idea. This comes with its RX1250X controller. The set is coming with one battery for the ATX1230 and one battery for the RX1250X. Know that both receiver and controller hold the same battery (GEB212). NOTE: No CF card (Compact Flash Card). This is popular memory card found almost every where. You may even probably have it in one of your numerous devices. Remember that the receiver ATX1230 is a GPS not a GNSS. So it tracks the GPS constellation (27 satellites: 24 active and 3 backup). It does not track GLONASS, GALILEO or BEIDOU or any other system. But it does work great without any issue. I do have GNSS antennas posted in my store as well if that’s what you want. The controller RX1250X has the following programs. It has some scratches and marks on the screen protector while the screen itself is being intact. I just don’t know what is it while it does not look like dead pixels. Fortunately, it does not have any impact on functionability of the device (view last photo). This set can be a good backup option if you want. Please, send reasonable offers. Low ball will be automatically declined. Even me knowing it. 1 X Leica ATX1230 receiver/antenna. 1 X Leica RX1250X controller. 2 X GEB212 batteries for antenna and controller.
