I have looked at many threads here, not found any that exactly answer my questions. I am extremely, and I mean really horribly far sighted. Had artificial lenses installed in the old eyeballs, due to previous surgeries and injuries I had to opt for a chance on overall good eyesight, or could take farsightedness 99% for sure and not so good up close. Being a dirt bike guy I took no chances and opted for farsighted. I can see a speck of dust on Pluto. As long as it's not too bright, too dark, and your dog named Pluto is close. So what I need is a HUGE screen. Every GPS I've tried to use I have to stop and get out the readers to read. (I use 3.50 readers). Can't keep the readers on my nose cause I get dizzy. Also, I ride some pretty gnarly single and two track, fairly fast speeds. Some "trails" I ride are almost impossible to see or find. I'd like a unit that is excellent in very remote places, with no or very few highways or towns to keep the unit oriented. Many of the areas I ride are very remote and only have USFS or timber company roads, and there are at least 5 different large timber companies around here which may or may not lend info to civilian use. So, I need a TV size screen with capability for the boonies. I do carry a map and compass at all times for backup. Elevation and direction would be nice, but an option. I'd like to keep the price under 350.00, don't mind buying used. I'll pay more if a necessity. Thanks.
