For long battery life (10hrs), four constellations, very lightweight, 8Gb static storage, small footprint, easy USB charger and low cost. I suggest you look at a Sokkia GCX3 “the bullet”.
This looks like the least expensive receiver on the market, no?

Probably not! Don’t let the ad’s fool you. The starting price is a boat anchor. You need to add Network RTK and GGD, also and Galileo is extra.
If you like the Leica measurement engines you can also look at the Geomax Zenith35 if you have a good dealer nearby? Can run with SurvCE/SurvPC and also their X-pad software. Very similar specs to a Leica GS16.
While the GeoMax GNSS may utilize the same GNSS board as the Leica GS16, I do not believe they utilize the same measurement engine.
They’re both boards from novatel and I’d assumed its novatel that makes the measurement engine for both from what I can find online. Leica just makes more useful software to run the engine? Do you have details to the contrary as I’d be keen to know?
Based on previous conversations with Leica personnel, they do not utilize the Novatel measurement engine, they develop their own for their survey GNSS sensors.
Do any of you use the tilt mode? How effective is it and the accuracy levels? What are the limitations?
Thanks.
I am generally against using tilt compensation for shots that need precision. Rtk is fast… But you loose a few hundredths of precision. A tilt compensatory adds to the loss of accuracy, no matter how good the compensator is. One that works off of gyros, will have some sort of maintenance issues, eventually. I say this, because airplanes have have them, and they have some maintenance issues.
I say, “tilt compensation, cool” but a well plumbed rod cannot be beat. Javad has them.
Now, whoever makes an auto reading rod length, that’s high reliability… They are gonna make money.

One thing I have heard from several users is to be wary of picking up points with the receiver up in the air. If you follow the conventional practice of leaning over an obstacle and placing the receiver head above the point you want then the tilt sensor will transfer the plan position to wherever the rod is pointing – not quite what you want to happen!
Just thought that I’ll share first impressions… I decided to go with Carlson BRX6 + with Carlson Surveyor 2 Hybrid 6.01 configured as a network rover on Nysnet. Overall, I’m pretty happy so far. The receiver is light, looks like it’s durable and well built, it’s easy and quick to fold down the gps pole and throw it in the truck, but Survce 6.01 has lots of glitches and it’s little frustrating at times. Hopefully they’ll release the new patch soon. It seems like something is running in the background and slows down the machine. I spoke with tech support, they couldn’t help. I’m running this with Leica 1201, you can save few $$ if you use Parani SD 1000 instead of upgrading to RH16 and CCP. I’ll try to test the GPS search in hybrid mode this week. I’ll share more shortly.
The dilemma of new equipment.
Since the following is all true:
You cannot live without it.
You cannot test all of it before you buy it.
You cannot figure out which brand, or model of a certain brand is going to be best for your needs.
So, this leaves us all with varying degrees of educated guesswork.
Having said that, if you could figure it all out, and buy the best for your needs, it’d all be out of date, in a month, or 3.
And, it’s all expensive. Then, I suggest that it’s a great time to be surveying!
Lots of good choices. Lots of tools.
You can’t afford it, and you cannot afford not to buy it. It’ll be out of date, before it’s paid for.
Cool, huh?

All true Nate, I agree with you.
