What is the diamater of this gauge? I'm looking for a small gauge for a back up
MONTE C 2.5 inches total. It's pretty compact.
LUIGI D i was a little disappointed it was much bigger than i had hoped when i received it, it is just under a 2.5 inch diameter (gauge and rubber housing)
KEITH B I don't have the gauge in front of me, but I use mine for the same thing... small, easily packed backup gauge (with no electronics) so I don't have a ruined, or rented, vacation dive. I'd guess it's about 2"... it's about what you'd expect of a single gauge.
DYLAN S Pretty much standard PG sized with the casing around it. ~2 inches. Not particularly tiny, but It's pretty small on its own
Jeff R I own 2 of them for my primary and backup rig. They are about 2-5/8" in diamter. With a caliper it is 2.6". It is easy to read and nice and small.
MICHAEL B This is not a small gauge. It is a standard 2" gauge, with a rather large cover.
