I'll add to all the agreements. In addition to the TDC150 then TDC650 shortcomings, the combination of the TDC600/TDC6, DA2 Catalyst, Terraflex, and Trimble Connect is still not to the level of efficiency we used to get with the Geo7X/Terrasync/PFO combo. While Trimble has made strides with these systems it's been several years since these have come out and IMO it still has a ways to go. I agree with Thomas' comment on a dream device similar to the integrated Geo7x and Joel's comment on all the peripheries you seem to need whereas in the past, you had one rugged device and with one battery. Even with the integrated rangefinder attached the entire unit was comfortable to hold, ergonomic, streamlined, and just had an indestructible feel to it (it practically was). Never sure why they could not take that exact same design and build it around an Android.

Couldn't agree more with the sentiment expressed here. I think some of the modernization were seeing is starting to backfire for those of us who do GIS outside!!!!. Frustration where it now takes 4 objects to carry (BT antenna, phone, battery pack, MIFI) and then middleware, and app. Enough to make the ole head spin, and I've been doing GNSS for 30 years. Explaining this to someone starting out.... good luck eh? then there is the touch screen....
If I had a golden request it would be to leverage the Android TSC5 (available for surveyors), a wicked RTK module (cm) or a helical WAAS hi precision antenna (solid 60-40cm accuracy) that a user could swap in/out. The TSC5 battery is incredibly powerful, keyboard/hot key assignment to collection... etc. Surveyors got it made with ACCESS on a TSC5!
Go GIS!

I completely agree. I've used both the Geo7x and the TDC650, and the Geo7x screen was far superior-especially in bright conditions and cold weather. The old screen worked flawlessly with any gloves or a stylus, while the new one is unresponsive and far less bright. It genuinely feels as though the designers of these newer devices completely ignored their intended purpose.
Unfortunately, all handheld devices have now been discontinued, leaving us only with the rather expensive Trimble Catalyst & DA2 setup paired with a phone. The Geo7x was compact, solid, durable, and shockproof, with an excellent screen, a swappable battery, and even a built‑in rangefinder-features that made it an exceptional device. I thinkTrimble made several missteps with the newer TDC series, which likely explains why they were all discontinued after just a few years.
My dream device would be a Geo8x with L1, L2, and L5 support, centimeter‑level accuracy, a built‑in rangefinder, a large swappable battery, 4G/5G connectivity, Bluetooth 5, a resistive touch panel with stylus support, Wi‑Fi 5 or 6, and the latest GNSS technology. The operating system doesn't really matter - Windows CE is obviously outdated, but it was simple, stable, and perfect for its purpose. That's exactly what we want, Trimble.
