looking for an oversized compass

[mjatkins]

I am finding lately that a significant portion of my students have a hard time reading an underwater compass, due to eyesight issues. Has anyone got any information about the availability of an oversized compass?

Perhaps your students should look into corrective lenses (contacts, prescription lenses in mask, gauge-reading inserts).

If they can't read a regularly-sized compass, e.g., Suunto SK-7, then they probably have a difficult time reading other instruments as well.

Thanks for the suggestion.

I already consider the Suunto brand compasses oversized.
Another option to go for is the compasses made by Sherwood and Oceanic. (same setup just different names slathered on)
What I like about those is that although they're kinda the same size as Suuntos (maybe smaller), they have less tickmarks so it's easier to see the numbers at a glance.
My only gripe with it is there's no bungee mount available =[

Do your students need over-sized SPGs, time and depth gauges also?

I don't understand your reference to 'vision problems' and how that only affects their ability to read a compass.

Compasses are generally manufactured in a comparable size to other gauges. The logic being that the divers vision should be sufficient to read a gauge of that size (whether corrected or not).

I am not aware of any 'over-sized' gauges available for sale. The answer is vision correction.

If your students can read their other (same sized) gauges, but not the compass, then I'd suspect that it wasn't eyesight at fault, but rather an inability to comprehend/understand the compass.

Was you at the Ultimate Diver Challenge dive site and saw the team with the giant navigation compass? Is that why you ask

Oversized compass with bonus over over sized computer.

with what looks to be an undersized bottom. timer

Just came up with a thought.
Have you tried pasting magnifying lens strips or bifocal lenses on the compass?
It may work, but it may also make it impossible to read the compass at certain distances or angles.

Is this what you are looking for? Sorry about the poor quality I took a picture of my T.V. with my phone.

Hollis makes one - from scuba.com it's a mere 1650.00 (I assume the actual one wouldn't have that bubble in it)
