After purchasing my Presto pressure canner with a dial gauge, I came across many references like the one below. Anyone know if this is accurate information?
Can the dial be replaced?

It may rock at 15# but it is a pressure regulator not a pressure "rocker" gauge. Pressure Canning is actually done at 10# not 15#.
Because dial gauges MUST be tested before it is first used and then annually after that before canning is started, many people today are going for the more convenient method of using a 3-piece rocker weight (Part #50332), which replaces the regulator weight. http://www.cookingandcanning.net/pr50prcaprre.html

Thanks mcnerd. My Presto is model 1781, the 23 quart, so it looks like that won't fit or work with my model.

Possible, but I've never heard of doing that. Do you live over 1,000 feet above sea level? If you don't, its not an issue.
Unfortunately the recommendation is to use a "dial gauge" when you live 1,001-2,000 feet above sea level. The reason for this is a rocker weight has to adjust from 10# to 15#, but a dial gauge only has to go up from 11# to 12#. That does less harm to the food being processed. If you live under 1,000 feet you want to be able to process at 10# pressure.

Yup, you're in that select group that will need to adjust every recipe for the altitude. So you have a choice of getting your dial gauge tested every year
or try the Presto option of just relying on the weight regulator. The dial gauge, for you, is better since you can use the 12# pressure. Otherwise you have no
choice but go to 15# using the regulator.
