Just wanted to thank you for the great support we got from both of you. S321 is working out pretty good. We went out to the site and the equipment performed nicely. We had a SureFix and it stuck throughout the whole survey, and even after dumping it, it picked it up so quickly. It was a beautiful thing….

It works well and I am happy with it. Topcon can be “tricked” by having a good fix then going into a very high multipath area. Hemisphere S321 will recognize the bad solution much faster and dump the fix. Hemisphere is also better at not giving a “bad” fix in an area like woods where there is high blockage and multipath. Topcon will give the fix but as soon as you start to move it will dump the fix. Hemisphere will hold off on giving the fix until it is actually good. There are some physical features that are much better on the s321. Price-point of Hemisphere is also very attractive. Overall I am happy with purchase and would recommend to others.

Just quick note to commend you on the s321 RTK system we just purchased.  It works great under tree canopy, it held a SureFIX in thick tree cover and saved me a bunch of time hiking with my total station.  The ties I’ve been getting have been extremely good when checking with my total station.

We love the new S321 GPS set that we recently received. I would like a quote on a second full GPS set just like the last one.

I really like the S321. Battery life is great, positioning is very repeatable and I’m liking Carlson SurvCE more and more. I’m very happy with it. Performance in and around trees is excellent.

A great unit. Did even better near trees compared to other GNSS Equipment I’ve used in the past. I will definitely recommend it to others.

Just an update, well Rene it’s the best built GPS I’ve ever used, I’m completely impressed with the design, the radio is way better now, and since the S321 firmware update it’s repeatability and accuracy has been dead on!Also this Mesa2 works awesome in every aspect daylight, it’s viewability is like nothing else on the market and in wet conditions the screen works flawlessly.

I can tell you everything works flawlessly and we would be in a very tight spot if you hasn’t been able to ship the gear that you did in such short notice ! Thanks a ton!! I love the s321 and I like the 15 min aRTK drift option on the 321, it helps us in a lot of situations.
