[Paddlewise] GPS Mount for Kayaks -- "Old Eyes" Problem

I have the "old eyes" problem, which prevents me from making use of the 
screen detail on my GPS unless it is within about 20 inches of my nose.

I have experimented with various locations, and it is plain that the 
sprayskirt deck is about as far away as I can place it and still use the 
screen detail.  If I move it to just in front of the cockpit (not an ideal 
location, in any case), I can not make out detail on Blue Charts, and the 
like.

What do others do about this?  (Those under fifty won't understand the 
problem, I suspect!)

I don't want to attach the unit to my sprayskirt because it may get in the 
way in a self rescue situation.  Lanyarding it to my PFD means I have to stop 
paddling to grab it to look at the screen.

I suppose a variation of those neck-based harmonica-holders like Bob Dylan 
used to use might work, but aside from the geek-factor, I really don't want 
something around my neck if I have to roll or dump out of the cockpit.

Has anybody with a serious bifocal correction solved this?

Thanks.
