SUBMETER HANDHELD?

Everyone would like something like that......The Mobile Mapper mode on a PM3 would probably be as close as anything you have mentioned....

I know nothing about any of this kit and software:

Anyone used any of it?

The Trimble Leap looks cool. I haven't used one, but I like the idea of using a smart phone v. the normal clunky hardware.

It is hard to beat SurvCE GNSS on a MobileMapper 120 with GLONASS. SurvCE GNSS will do everything you would ever want to do, in the USA you will get 1/4 meter horizontal repeatability (elsewhere just 1/2 meter) on the MM120, GLONASS makes it work under moderate cover reasonably well (but still with a loss of precision.)

I'll take a look at it. I emailed you guys for a recommendation before posting, but didn't hear anything back, so I tried here.

Plus you get Mark Silver for support which is priceless, no joke!

T.W.

Take a look at the Leica Zeno 20, capable of 5cm or better accuracy as a handheld plus it appears to be a lot of other added benefits.

Unless you can get a steal on a MM120, I wouldn't recommend it. The GNSS performance is the only upside, the hardware itself isn't what I would consider reliable.

Mark, I couldn't find that set up on your site. How much does that run with SurvCE?

Yes, the GNSS performance is great, but the platform can have issues. No WiFi is a big deal.

Figure in the cost of a 2-year extended warranty (which extends factory warranty to 3-years) [$556] then you basically know what it will cost over it's life.

They appear to be crazy expensive, but when compared to other solutions, not so much...
