PLEASE NOTE: No UK power supply is included with this kit. You will need to supply our own appropriate USB 5V, 2A charger / supply.

The RTK Surveyor is a Bluetooth® enabled multi-band GNSS receiver based on the ESP32 from Espressif and the ZED-F9P from u-blox. Flip the switch and you'll have 300mm approximate accuracy out of the box and 18mm accuracy with RTCM corrections. This kit provides the L1/L2 antenna, adapters, interface cables, and chargers needed for general GNSS use.

We generally recommend using your cellular phone as the radio backhaul for RTCM but you can also use your own, higher power radios as long as they support 57600bps. We also recommend logging all data to your phone over Bluetooth. This is as simple as checking a box within SW Maps. But if you prefer to do long surveys, or need to deal with RAWX measurements where a phone will not be present, a microSD card should be purchased (any size up to 32GB).

Please keep in mind that you will need to provide your own mono-pod or tripod as well as a cell-phone type holder for securing the RTK Surveyor to your mono-pod or tripod.

Note: The L1/L2 antenna has a 5/8" thread which will fit most surveying platforms. The kit includes a 5/8" to 1/4" adapter as well which will fit most camera mono-pods and tripods. You may need additional adapters for your specific equipment.

Stunning Automatic Watch With TopTier Durability and Precision
Color: Grey
“I got this Tissot PRX for my cousin’s birthday and bro fell in LOVE instantly. This thing keeps time like a beast, never slows down, never lags. Automatic movement, so no batteries, no drama. Durability? Stupid good. You can hit it, bump it, live life rough, it still looks box fresh. Size wise it was almost perfect. I just had to remove two links, nothing big. It’s light, functional, comfortable, doesn’t weigh you down, doesn’t get in the way but more importantly I can say this watch is in everyone’s eyesight when we wear it. Cause of course I had to get another one! Basically. I gave him a very nice piece as a gift, and now he’s walking around like he owns Switzerland.

Excellent value for an automatic watch, keeps VERY good time.
Color: Grey, Color: Grey
I've only had the watch for a day but wanted to leave a quick review on it to share a couple of notes. So far it keeps VERY good time, better than any of the automatics I own (including a Rolex Submariner, Tag Heuer Aquaracer, Tag Heuer Formula One, and several other sub $1k watches). I set it to an atomic time app on my phone yesterday and 24 hours later it's still SPOT on - hasn't gained/lost even a 1/10 of a second. I was shocked to see it's kept PERFECT time for the last day, I'm really blown away so far. I've worn it the entire time, we'll see how well it keeps time while being stored in a winder. This picture shown is the watch with a 22mm leather band on it, fit's without any issues (just need to squeeze in the leather a tad). I doubt it would work with a 22mm metal bracelet, but leather works great. Just FYI since the 21mm lug width is kind of odd. The face isn't quite a lustrious as the images make it look, but it's still a great-looking watch. For a sub $1000 automatic you can't go wrong, this is a fantastic watch at a great price. It'll be my daily driver for some time I'm sure. If I have any issues in the future I'll update the review.

Really cool and beautiful watch. Although my specific unit runs 5 seconds fast every day—at first it’s annoying, but eventually you stop caring. 🤣
