Anyone who read my previous Canmore GT-730FL-S review is probably wondering why I got this device. Simple. I lost the 730! (Hooray! I found it again on 27/12/2014)
I nearly bought another 730 as the replacement but thinking about the minor gripes I had with the device I thought that the 740 may resolve most of them.
- 730 silver cap and rear scratched very easily making it look shabby. The 740 doesn’t have the nice rubberized coating, but its black plastic doesn’t seem to scratch as easily and certainly doesn’t show the scratches as much. You can get a 730 in black, which I did consider.
- On/off slider switch could be accidentally knocked on the 730, but a really firm two second hold is required on the large rubberized 740 button.
- The waypoint logging button was always getting fired in my pocket on the 730, so I had to edit out the waypoints in notepad++. Again the 740 button needs a good firm press and hold, this time for just one second.
I believe that when you strip away the case and buttons the two devices are identical except that the 740 has a G-sensor. This means that if the unit is stationary for 5 minutes it will stop logging your position thus saving power tracking satellites and writing to memory. It only takes the slightest movement for it to wake and start logging again and this process is almost instantaneous. If you left the 740 on a table overnight it would hardly drain the battery at all, hopefully leaving you plenty of juice for the next day, whereas the 730 would have been recording the same position all night and may now be drained just when you need it. The 740 claims to be able to run in standby mode for 1500 hours when fully charged.
I’ve just left the same drivers and Canway software on my PC as they are clearly the same files for the 730 and 740. On first power up after traveling thousands of miles to the UK from Taiwan via Germany there was a satellite fix (whilst indoors) within just a few seconds. The truth is that I switched it on, went to redirect my phone, turned round and it already had a fix. Each time I have subsequently turned the device on the fix has been made in less than 5 seconds.
The cap is very hard to remove, though this is probably a major contributor to it being IPX-6 waterproof. I was concerned that the 370 cap would get lost one day as it comes off pretty easily. It seems very unlikely with the 740.
While the 740 comes with an armband there is no means of attaching a lanyard. The device is marketed as a Sport Log Book, which is a bit silly really. As I have said, it is really the same device as the 730, which is not marketed in this way.
As with the 730 I ordered from digital-paradies (they also sell via Amazon now for a fraction more) and was a bit disappointed that the postage was £7.05 when the same company charges £4.99 to deliver the 730. Units and boxes are the same size and weight.
Standby Test added 9/3/2015
In response to Stratos’ post on the GT-730 topic I decided to conduct a test to see how long the device would run when used for a period each day and left it to go into standby mode.
I put the receiver in my car on 28/1/2015 after fully recharging it. It was configured to record location once every second. The car was being used generally twice a day for short trips (4-8 miles) and 4 or 5 longer ones (25-35 miles). It recorded for around 10 hours over a period of 15 days before the battery finally ran out.
I thought this was pretty good, though you could always charge the device from a portable charger or from your car cigarette lighter. Many newer cars even carry USB ports these days which you can charge from.
