Just a note I, and am sure many others, enjoy your calm and thoughtful
responses to postings.....others could learn from that....

Just thought you like to know....

Can't speak to the transflective part but I have tried all three
technologies,IR,capacitive and resistive on my CNC router. I can pretty
well confirm that none have a place in an open cockpit. If a drop of water
hits an IR screen it will pop up a menu and ignore your finger. Same thing
for a capacitive except that a thin coat of dust will confuse it too. The
resistive is better than the others but will pop up a menu if you cough at
it so no telling what it will do in a 20 knot wind.

I am putting the resistive screen in the nav station and a straight
transflective on the binnacle with a waterproof industrial track ball
mounted below it. Even then the touch screen will have a track ball too.
Touch screens are great for Kiosks and programs that have big buttons but
suck when you need accuracy. I have been playing with a couple of chart
programs using the touch screen. It is impossible to put a waypoint exactly
where you want it. You just can't get the position accuracy with your
finger that you can with a traditional mouse or track ball.

Thanks for the various inputs on Touchscreens.
Sorry to post again, but the original subject is rather old now,
originally posted on 8 July.
I have been in contact with various UK suppliers, and they all seem to
think there is no problem with the transflective side.
Then comes the next argument. One supplier says they only way to go is an
Infra Red touch screen sensing arrangement, another supplier says Infra
Red is unreliable, you must have a resistive screen. The original supplier
supplied a capacitive screen which worked well on the odd occasions when
it was bright enough to see.
Another problem is the bezel round the screens which are quoted as
aluminium. I haven't yet managed to find out if it is anodised.
Before lashing out £800 to £900 I would welcome any further comments.
