Handheld GPS--key features?
As a slight change to the model v model; I would appreciate any strong views (it's Pprune so hopefully I've come to the right place) on the features you have found, through experience, to be the most important …....and those you could do without. For example;
Is a 7'' screen so much better than a 4.2'' or a 3.8'' ?
At what size does a handheld start to become too bulky?
Ability to fix safely in cockpit?
How important are the different screen resolutions and refresh rates?
What do you view as crucial connections?
What do you view as crucial battery life?
Types of GPS receivers?
If you can't connect to the internal electrics do you need supplementary batteries and what are the best sort?
Are all touch screens the same?
Advantages / disadvantages CAA map loaded compared vector map?
I ask just to aid in the decision making process. With the plethora of new designs in this sector peoples experience of what really matters would be helpful. For sure peoples requirements differ ;mine..shortish transits in a Pitts (UK only) is likely to be different to yours.
