I just noticed a used Surveying Equipment reseller when I signed into Surveyor Connect. They have some pretty good prices if you dare to go without Dealer support. Hassian Survey surveyhas.com.
I know nothing about them.

Pretty sketchy I think. Based in Indonesia.
These are just some of my opinions, and thoughts based upon a lot of experience in the seismic survey world, with a lot of different equipment.
The Javad equipment is very intriguing. The Triumph LS all in one unit mounted on the pole would be ideal for the more precise surveying, or high resolution seismic you may be surveying. I have concerns with the unit if I am walking/stumbling/falling through brush though. Most seismic surveyors are accustomed to using a backpack mounted dome, and hand held data collector if they are surveying on foot. The Triumph LS would preclude that capability unless you used an external antenna (this could be a very good solution for vehicle mounted systems though.)
Javad also has what I guess I would call a more conventional system. The Triumph 1M, and Victor Data Collector would give more flexible mounting options, and be a more conventional form factor.
I am also curious about the actual range possible with the 35 watt radio modem. I have seen several people claim trouble reaching two or three miles.
These are isolated incidents, and there can be many reasons for those issues, but that is far too short a working radius from the base.
One of my concerns with either of the Javad systems would be the post processing of data working for several clients who require the raw positional data to be collected in WGS84, then transformed to projection desired.
The industry standard software for that is GPSeismic. It is a Trimble product, and I do not know if the Javad raw data format is supported by the latest versions. I know there are utilities in GPSeismic that are supposed to handle Javad data, but I have not used them.
I also do not know if Javad will export a SegP1, or UK file format of the collected coordinate data if you are not required to postprocess. Converting the output files to another format could be scripted, or programmed for fairly easily, but it would be another thing that would have to be done beyond training an unfamiliar system.
All that being said, the price is great. $25,000 for a base, and rover unit with what I feel are some stunning capabilities should you choose to take advantage of them.
With regards to the rugged tablets.
Yes, they are very nice, and very informative. They are also expensive, and break easily. Sorry, we are in a rough business. The smaller the collector, the better for durability, or they need to be relegated to a vehicle mount. People fall down too often in the seismic industry. You have been through the safety meetings. Slips, trips, and falls are frequent topics.
The Trimble R10's are another amazing piece of equipment. They are proven in the Seismic industry, seamless data processing in GPSeismic, with personal support a phone call away from the developers. (I won't name names, but they are some great people!)
You also have direct file translation to ESRI products if you use them.
You are going to pay a higher price for the level of integration they provide though.
I have seen, and heard the claims about work under canopy by every manufacturer. I have seen videos, and they are all quite impressive. I have seen live demos, and I was impressed by what I saw.
What you may want to do is schedule a demo in the Big Thicket, or someplace like that. All of the demos I have witnessed have been under deciduous trees, seldom any conifers/pines in sight. Try getting lock in between a couple large Scotch, Loblolly, Yellow Pine, or Blue Spruce trees. Leaves are easy, needles are not.
Just one fool's thoughts, and opinions, and I am probably wrong.

I just bought a TSC3, because my last TSC2 died (pretty much, still works but the screen is not working totally). I knew there was a new Trimble data collector coming out, but I could not wait. I also have a Yuma Tablet, but for total station work on locks and dams I prefer the form factor of a TSC3. Much easier to carry in one hand. When we work on dams we aren't using a pole, just a mini stakeout prism, so nowhere to hang the DC other than on a lanyard or carry in one had. The new data collector apparently uses windows (like the Yuma), but I have not seen it or any specs.

Thanks for the reply. I have been in the field since last month working 7 days a week and 11-12 hours a day in the field so I don't get a round to checking the forum everyday.
We don't do our surveying like traditional seismic. I own a seismic crew and we do our own surveying in house. We survey our receivers (which are wireless) in real time as we deploy them and we have a surveying instrument mounted on our source unit and survey source points in real time as we shake them. No pin flags.
I have messed around with an old version of GPSeismic way back in the late 90's or early 2000's but I don't use it. I just use TBC or even the data collector to export CSV files and then pull them into [REDACTED] and I can create SEGP1's there.
I do have ArcMap and ESRI software on Trimble Nomads we use for GIS level stuff but I don't use the software very much other than what I need to for those specific applications.
I may rent a R10 and try it out.
If you use this new equipment the same old way to do the same old things you aren't likely to see a lot of upside. You already have the GLONASS, that's the main thing.
I have used Leica for a number of years for many reasons, it is good gear however a primary reason is every piece of equipment coming from the same manufacturer, regardless of color, I just happen to like green 🙂 Life is just easier not always trying to get this to work with that, some vendor most of that is gone.
Having said that, if I was upgrading, I would look at both the Javad units and the Septentrio units, although the new Leica GS18 T is very interesting too.
The Septentrio brand has been around for awhile and the Altus receivers used those boards prior to being absorbed by Septentrio. I look at equipment for what is under the hood as much as the flash the sales folks show you. In my business I process GNSS data from about every make of receiver at least once sometime during the year, those Septentrio guys know how to build a high quality measurement engine and I can't believe I am saying this, BUT I think it may be better than the Leica units (NovAtel boards).

I purchased an X91+ from Igage at the end of last year. I have been happy with my purchase. The price is also very reasonable. I keep seeing their advertisement scroll by as I go through site. I believe the new model is the iG3. It's worth looking at. Contact Mark Silver on this site
Just my .02

UNAVCO has been putting Septentrio PolaRx5 receivers in its more recent PBO stations.

Yes I know as well as ODOT for the Oregon network, I base my previous comments on conversations with a few network operators who have installed them and my own experience in QC'ing the data and using it, very low noise receivers and they just work! I never have to worry if the CORS that has one of those Septentrio PolaRx5 installed is going to be quality data or not 🙂 Can't say the same for many other receivers out there, although every vendor is getting better, there are still some that I prefer not to use.
