Columbus V-900

GPS guy — Wednesday, October 21, 2009 - 06:20

Anybody having a problem getting correct altitude from the V-900? Just bought mine and altitude data seems bogus.

Very good review there.

Very good review there. Awesome information.

I am surprised to see AGL3080

I am surprised to see AGL3080 works based on AAA type batteries, do you have any recommendations? I doubt all the batteries will keep it working for 15 hours.

Comparison

First, thanks for all the information and help you provide.

Now the problem, I have been looking at to many reviews. I am looking for a simple, easy to use GPS logger for recording my family's trip across the country and Geo tagging our pictures. I have been looking at the Amod AGL3080, Columbus V-900 and Holux M-241. Which unit would you suggest? The display on the Holux attracts my attention because of other activites such as camping. You can display your current position or the distance that you have traveled (straight line or by points).

Thanks in advance.

this device is really the one

this device is really the one who are considering to buy a photo tracker as well. I bought mine at bedoxinc.com . They offer a free windshield mount with this unit.

Thanks, Kevin!

Thanks, Kevin! I think I'll go with extra sets of batteries. The Columbus has an internal battery and that won't be so convenient as I will not have access to power for parts of my trip.

AMOD AGL3080 battery life

Kevin Jaako — Friday, May 8, 2009 - 17:53

Hi Jay,

I was wondering if battery life will improve much if I change the recording frequency from once per second to once every 5 or 10 seconds? Will this allow me to keep the unit running for 5 or 10x as long on a single set of batteries?

Nope, sorry.

The AGL3080's SiRF III chip (the actual GPS chip) stays on and powered 100% of the time, regardless of which logging frequency you chose. Saving data to memory uses a fraction of the power that it takes to keep the SiRF III GPS chip running.

You'd be better off either investing in a few sets of rechargeable batteries or buying cheap disposable batteries in bulk. You can also look into GPS dataloggers based on the MTK chipset, such as the Columbus v900 , which can get almost twice as many hours per charge as SiRF III based loggers and investing in a solar-powered recharging device.

I hope this helps!

Battery life with reduced recording frequency

Jay — Friday, May 8, 2009 - 08:51

Great review! I am also going on a long trip and it won't be practical to bring a large number of extra batteries nor can I buy batteries while on the trip... I was wondering if battery life will improve much if I change the recording frequency from once per second to once every 5 or 10 seconds? Will this allow me to keep the unit running for 5 or 10x as long on a single set of batteries? Thanks!

AGL3080 data retention

Kevin Jaako — Tuesday, May 5, 2009 - 22:37

Hey Mitchell,

I can just turn the unit on in the morning, off at night, change the batteries, rinse and repeat every day... and I won't have to sync the data with the photos till I get home from the trip 12 days later?

Correct!

The AGL3080 EASILY has a week's worth of storage capacity. You should have no problem waiting a week before downloading and sync'ing your data. Just make sure you shut down the AGL3080 properly every night before changing batteries! As long as you remember to shut down before changing batteries, your data will be safe and sound, even without any batteries in the unit!

Good luck!

Ah. I misinterpreted the

Mitchell Rose — Tuesday, May 5, 2009 - 09:56

Ah. I misinterpreted the manual's saying "Battery cannot be removed while the AGL3080 is still turned on and functioning. If this happened, the power to the device will be out. This power outage will cause the logged GPS data not being properly saved and thus permanently lost." The operative phrase there is "turned on and functioning."

I actually meant take out one battery then put in a one fresh then take out the next one, etc. The idea being to keep a little charge going in to maintain the data. But you say data is maintained in ROM anyway.

So, if I'm in 10 second sample mode for a 12 day trip, you're feeling is I can just turn the unit on in the morning, off at night, change the batteries, rinse and repeat every day... and I won't have to sync the data with the photos till I get home from the trip 12 days later?

Thanks so much for tolerating the rube.

Mitchell
