I was trying to provide Geos with adequate information on my insurance situation and medical records, as those would be important information to have in a real emergency. However, the field where you can enter additional information for emergency responders has a very small character limit.
I would like to see this expanded to accommodate more information.

Sometimes it’s more effective to use my local UK OS 6 or 8 figure grid system for locations rather than sattalite coordinates. And have the ability to change this on the fly with a mobile app

Well, if you use a device like the spot, maybe it is possible, that you are outside... without a roof, inside a car or an umbrella.
Like me, on a bike in Kenya. After a heavy rain, where the spot was mounted at the dashboard (not under the mudguard or inside the cooler), the spot quits his job.
If you read a list on wikipedia, 507.3 defines only humidity, no rain or immersion.
You can buy the cheapest watch from china, which is more waterproof then the spot...

I was told that there is no way to enter SPOT data into SARTopo. SARTopo is the system used for search and rescue ground teams in many states.

I would like to send tracking information to the e-mail addresses listed in the ACTIVE PROFILE automatically when tracking starts.

Ping my location every one minute instead of every 2 1/2 minutes.

Send automatically a message if the speed drops below defined speed for more than 1 minute. This could be used for automated landing message of aircraft, aircraft logbooks, automatic tracking.

The function buttons on our SPOT gen3 have all rubbed clean - no labels visible. Fine for my wife who uses it regularly but hopeless for me who uses it only once or so in a blue moon - no idea what button to press to say I'm OK or to track etc etc. Perhaps colour-coded buttons or deeper etching and better inking of the label icons into the surface of each button? (otherwise a brilliant device, thanks!)

to be able to send a voice message throught gen 3

Send an image through a small internal camera.

I would like to see how far I had hiked between two points. For instance, I want to know how far it is between way point (or whatever you call them) 12 and waypoint 25, for example. If this already exists, I am not sure how to activate it.

Il serait bon d’etre
Capable de pouvoir ecrire des messages texte comme le (in reach) par exemple

For aviation usage (as replacement for Emergency Locator Transmitters) even the Extreme Tracking Interval is too long. With the typical travelling speed of a modern glider of approx. 120 - 180km/h (33 - 50m/s) the distance between two fixes comes to 5 - 7.5km. This is clearly to distant in case the data shall be used for SAR purposes. A tracking intervall of approx. 30 seconds would be great.
It is clear to me that this service would cost more. I would be gladly prepared to pay for this extra safety gain!

Allow you to find friends in the same área would be very helpfull to find friends you might want to meet or also people that may have got lost of you or a group.
