We have found that there's a website where an "expert" mentions that "Deluo is now globalsat" (, and people have been contacting us for support on Deluo products. So we just want to make it clear...

USGlobalSat has no relation to Deluo. USGlobalSat did NOT purchase or acquire Deluo and we do not provide any support for any of their products.

Please feel free to contact us directly if you have any questions about this topic.

Hello Randy & dusteel,

The cost for shipping is basically the cost that UPS charges us. We have added another shipping option, which is USPS First Class, which we will ship the bike mount in an envelope.

If you are interested in purchasing a bike mount with this discounted USPS First Class option, then please use coupon code USPSDISC, and it'll deduct $9 from the shipping cost at checkout. This coupon code will only work with the Bike Mount and only with USPS.

Let me know if you have any questions.

C'mon, $10 for the mount and $10 for the shipping! (in the US) the whole thing should be $10 shipped. I use the original mount on the bike that I ride most and one of these rubber bands ($1.40 shipped) when I use it in any other bike.

I have been using this watch for the last 3 years, usually once a week when we do our jungle trek/run. Most of the time I do wash it under the tap after I get back and did not have any problems. I used the watch on Monday and fortunately it did not rain. As mentioned before, the distance appears to be correct but the attitude reading is wrong. Guess I just have to live with it. By the way the start/stop cover broke off. It is now taped back to the watch but it works.

Hello Dmac,

Sorry to hear about your watch problems. The GH-625M has an IPX7 rating, so running in the rain shouldn't be a problem. If moisture leaked into the display area, then there might be a compromise on the seal around the display. How long have you had the GH-625M? And where did you purchase it from? It might be covered under warranty, if you purchased it from an authorized reseller & it was purchased within a year. If it's not, then your best bet would be use the blow dryer and the sun and see if that helps revive your watch.

Hello pmuyter2014,

I'm not that familiar with how to use a BU-353 as a time source, but I can try and help resolve your issues.

1) I use the time and date from the GPRMC message, and relate it to the timestamp of the '$' character in the previous GPGGA message, which has the same time information, using a program in the highest priority on my linux boxes.  Is that the right way to do ?
That sounds like it should work. Have you tried referencing just one NMEA sentence instead of looking at two different ones?

2) I have noticed that the messages do not come regularly every second; they are frequently delayed, and sometimes are even delayed by many seconds.
Each NMEA sentence will output every 1 second. For example, the RMC sentence will output every 1 second and every GGA sentence will output every 1 second, but they output every 1 second independently from each other. At least that's how I understand it. Are you seeing something else?

3) When I take only the time given by the gps receiver for messages that came "in time", and compare it to a stable ntp source, I notice that the difference decreases over time, and then is reset to an initial value, then decreases over time with the same slope, then is reset to the same initial value and so on, giving a sawteeth graph, with a quasi-constant period.  Each gps receiver exhibits the same behaviour, but with a different period.  The time jump at the reset seems to be the same for all gps receivers: about 100 ms.
I'm not sure exactly what kind of time accuracy you can get out of a device like the BU-353. But from my understanding, the BU-353 is not designed for precise time accuracy. If you're looking for more precise time, then I would suggest a device like the MR-350P-S4, which has a 1PPS output synchronized to GPS time:

Let me know if you have any further questions. Thanks.

Hello dusteel,

What specific part are you referring to? There's no "computer mount" for the GB-580. Are you referring to the Bike Mount? If so, you can purchase the Bike Mount here:
