I made the comparison table (below) to compare the Spectra Precision SP60 and SP80 products.
Let me summarize the differences:
Price SP60 costs 11% less. SP60 does not have hot swapable battery. SP60 does not have nifty display. SP60 does have L-Band for Centerpoint (nifty but none of my customer will use.) SP60 has 1/8 the internal memory. SP60 does not have an internal cell phone. SP60 does not have internal Wi-Fi (which is kind of a deal breaker for me, I love the internal Wi-Fi!) SP60 does not appear to have tilt sensor.
|Cost for L1L2 GNSS UHF Rover
|Built in Wi-Fi
| Internal Static Occupation Memory
| Maximum Recording Rate
|L-Band (RTX Center Point Support)
||2.1 EDR Long Range
| Bluetooth for Site Corrections
| Internal GSM Cell Modem
||3.5 G QuadBand
|Number of batteries
|Battery Life (GNSS + UHF Rx)
||930 g (2.1 lb)
||1170 g (2.6 lb)
||32 GB SD Card
|UHF Radio (exact same for both receivers)
||Lock to Location
||Lock to Location,
SMS, EMail Msgs
So what is going on here? My guess is the SP80 is positioned to be the choice for most typical sales. And my guess is the SP60 is a price-point flexible offering. So you will see deals, trade-ins, promotions, discounts, specials, great quantity pricing and super-duper pricing in South America and Asia.
But I won’t know for sure until someone comes along and tries to purchase 20 of them at once!
Spectra Precision is offering a substantial trade-in program for converting ProMark 3 receivers to the latest SP-60 receivers. If you have ProMark 3 receivers and you are thinking about upgrading to state-of-the-art receivers, now may be the time.
Here is the redemtion table:
||PM3 Trade-In Value
||SP60 L1 GPS Single Receiver Kit
||SP60 L1 GNSS Single Receiver Kit
||SP60 L1/L2 GPS Single Receiver Kit
||SP60 L1/L2 GNSS Single Receiver Kit
w/UHF 430-470 MHz 2W TRx
So a pair of ProMark 3 receivers would have a trade-in value of $2,800 towards a RTK pair of SP60s.
Additional information with list prices can be found here [ SP60 Information ].
If you are considering taking advantage of this program, please drop me a note or call so we can figure out which data collector you will need, I will get you an ‘official’ quotation.
Terms: There is a lot of factory fine print, here is the important stuff:
- Acceptable trade-in units include survey grade L1 or L1/L2 receivers with part numbers 800520-02 and 800488-03.
- Trade-in receivers have to be tendered to us before we will ship, however all we need is the receiver bodies. We don’t need cables, antennas, power supplies, batteries and other accessories.
- You can’t combine offers.
- USA and Canada delivery only.
- Offer ends March 31st
There is, in fact, a risk of loosing valuable data that you collect in any field program. On most of the newer data collectors that we sell (Carlson Mini-2, Carlson Surveyor-2, Nautiz-X8, Ranger 3…) the operating system is loaded in the same space as the program and data files.
If anything goes wrong, you must reinstall the operating system from scratch. This wipes out your program installations and it will wipe out all of the data that is stored on the device.
Many customers choose to store data on the SD or micro-SD card that typically is loaded in the battery compartment. But there is a significant speed decrease in using SD memory on most data collectors (see [making-survce-fast-survey-store-points-faster].) The SD memory access sometimes is 100 times slower than the main memory.
Luckily SurvCE has a simple mechanism that allows you to continuously back-up your work during the day.
First make sure that your data collector has a SD or micro-SD card installed. These usually are placed in the battery compartment.
When you start a new job put it in the main memory. The default location in SurvCE is “/Device/Program Files/ SurvCE/Data/”.
Immediately after you start a job from the main menu go to ‘Equip: 6: Data Transfer’:
Click on the ‘Set Storage’ button, navigate to the SD card (often called ‘Storage Card’) and configure the destination to be a new folder. I like to use ‘SurvCEJobBU’ because it makes sense:
Once the folder is configured, click on the ‘Copy Crt (current) Job to Storage’. It will take about 1/2 second to replicate all of the job files in the backup location.
Now, throughout the day when you have collected enough data that you think it would be a bad deal to loose the recent changes, return to this menu and just click the ‘Copy Crt…’ button again.
