The same area are shown with BlueChart 8.5 and Bluechart g2. Colorado-300 shows that the buoy drawing is incorrect on Colorado-300.

2. Depth of obstructions

If you have a bout that requires 2m free water and want to navigate in this area

Point on it, is it safe?	Press enter: Underwater Rock

3. Tides has wrong time format, and can only show tides for current day

Tides

Tide times are shown with "12-hour clock" format even if your setting is "24-hour clock"
Somtime it's important to know tide times for next week, or next month. This is not possible.

4. Course pointer, what's wrong

Course mode I	Course mode II

The manual does not anything about course pointer. Anyway it's reasonable to guess that the red arrow points out the course and the blue triangle points out the bearing. It does not. The blue triange points in the same direction or the opposite direction of the course. This must be an error.

5. Global setting/Profile setting - Select map

Global map list

The map selection list is common for all profiles. The map selection list should of course follow the profile, such that you have a Topo map for Geocaching, A BlueChart g2 for Marine, Navigator for Automotive and so on. THis should work even if you have maps on different SD memory cards. If you switch SD card or switch to a profile that requires another SD cacrd, the software should promt for another SD card or ask the the user if he/she wants to switch to another profile.

6. Global setting/Profile setting - Compass bearing/course mode

Bearing mode	Course mode

I guess that Course mode is very useful in marine mode (if it had worked), but not very useful in Geocache mode. Unfortanatly this setting is not attached to a profile, it's a global property. So if I set Course mode when I'm navigating a route in marine mode, end then go on shore to find a geocache I will switch to geocache mode. Then I'm still in Course mode, and I'm stuck in this mode since the option pane isn't available in Geaodache mode (see error xxx). Mode setting should be a profile propertiy.

7. Global setting/Profile setting - Compass Automatic/Off

Auto/Off ...	Electronic compass or gps compass

The electronic compass is useful, but sometimes, for example in a sailboat with low speed it's necessary to switch the electronic compass off, and that arises a lot of problems:
1) The setting is global
I think it's useful to set the compass off in marine mode. When I switch back to geoacache mode the compass is still off.
2) The setting should be on the options pane.
As it is today this setting is almost impossible to find. It's in the setup-menu for "Heading". It’s a very strange place to put this menu item.
3) The user should have the ability to set parameters for when the compass shall switch from electronic compass to gps compass.
4) The compass page should show an icon showing if it's in electronic mode or gps mode

8. Option pane in geocache mode

Auto/Off ...	Electronic compass or gps compass

In geocache mode the options menu is gone. This means that you cannot change data field without exiting geocache mode go to the map or compass page outside geocache mode and then reenter geocache mode. This is extremely irritating in compass page if you want to switch from course mode to bearing mode. In this case you have to exit geocache mode, start a new navigation, go to the compass mode, switch to bearing mode, stop navigation, and then reenter geocaching mode. It's a pain.

9. North up/track up

North up	Track up

I think most people like to see a world map, a country map or a county map with north up. When you are navigating in the forest or with boat in the skerries, it's good to zoom in and with the gps with track up. So I really mitt an automatic switch between north up and track up, and that is possible to set the zoom lever where the mode will switch. I also miss to have this setting in the options menu.

10. Map panning

Map panning

When panning across a map it should be useful to see distance and bearing to the cursor location. In the figure I have given an example of how this information may we written in the bottom of the screen.

---

11. Sound/alarms

Sound menu	Alternative sound menu

Sound on/off is not good enough. I really hate key click on my electronic devices, and I think people around will go mad if I have key click on. On the Colorado the only choice is sound on/off, so when I turn off key click I also turn off messages, alarms, navigation etc. This is too bad. I have shown a good alternative where you can select individual sound for key click, on/off, messages and so on.

12. Mark waypoint

Mark waypoint	Edit waypoint

It seems that Mark waypoint does not work. It really doesn't matter since it's also possible to mark waypoint by pressing the button in 2 seconds more.

From a geogachers point of view, just to mark a waypoint is too simple. When you put out a new cache you will probably try ta average the position over 5-10 min. There are no such functinality on the Colorado.

If you want to create a new waypoint the easiest way is to mark a waypoint and then edit the location. I woulud really want to edit all data on one page insted of going bach and forth between edit name, edit symbor, edit position etc. When I edit the position I really want to see the entire position string to see if it's correct entered into the GPS.

13. Design vs readability

Soft Key Color	Computer page

Im sure a lot of work has been done to improve the design on the unit. My wishes is less design and more readability.

It looks nice to have different background images with different profiles, but she background disturbs the readability. I have found that the best background is a uniform dark (not black) image.

When you feel that a lot of functionality is missing it seems funny that it's possible to change Soft key color. Does it really matter? If I had an option to change color on any elements I would change color on the track log. The black line in the tracklog mix up whith the map and decreases both the readability of the map and the track log.

In compass page, course mode, it seems strange to use a triangle as a direction pointer since a triangle points in three directions. I know I must look at the dotted line, but a triangle as a direction pointer is only for the design, and decreases the readability of the bearing pointer.

The font selection for the computer page (and a couple of other places) is an old calculator style. This font type has lover readability than fonts with rounded symbols.

A lot of talk about readability, but it is important. I don't use my GPS at the office. I use it outdoor and the weather condition can be bad. I don't want to get lost just because someone lets design go ahead of readability

14. Other

The limitation on number of geocaches should be at least 10000, today this limitation is 2000.

There is a strange limitation in the GPX-file size. It seems that the total size of the GPX-files is limited to 10Mb. This limit must be removed.

Off course data field must indicaate if you ar left or right of the courseline (as for the Gpsmap76S).
