Presto 01781 vs 01784
Two 23-quart canners with nearly identical specifications and one difference that matters only if you have a specific kind of stove.

The Presto 01781 and 01784 are both 23-quart canners holding 7 quarts or 20 pints, both dial gauge, both 12-year warranty, and both double as boiling water canners. The only meaningful difference is the base: the 01784 has a stainless steel-clad base and works on induction, and Presto states the 01781 does not.
This is the rare comparison with a genuinely short answer, and it is worth writing down precisely because the model numbers are one digit apart and the listings look interchangeable. If you have an induction cooktop, buy the 01784. If you do not, the 01781 does the same job.
Below is the specification-by-specification version, because the surprising part is how little else differs.

Ten of eleven rows match. That is the finding.
The one row that differs
Presto's Canning Heat Source page states it about as plainly as a manufacturer can: except for Stock No. 01784, standard Presto pressure canners do not work on induction ranges. The 01784's stainless steel-clad base gives the cooktop the ferrous metal it needs to induce a current; the 01781's aluminum base does not.
This is not a performance difference. On induction the 01781 does not heat slowly — the cooktop does not switch on at all. The full explanation, and what to do if your cooktop still refuses the 01784, is in canning on an induction cooktop.

Presto 23-Quart Pressure Canner and Cooker (01781)
The default first pressure canner, and the one most beginners should buy: it takes a full seven-quart load, it doubles as a boiling-water canner for pints and half-pints, and it costs a fraction of a cast-aluminum canner. The dial gauge is the catch, and it is a real one.

What works
- Seven quart jars is the standard batch size every tested NCHFP recipe is written around, so you are never processing a half load
- Doubles as a boiling-water canner for pints and half-pints, which means one pot covers the jam-and-pickles year as well as the beans
- Presto sells a replacement dial gauge and sealing ring separately, so a decade-old canner is a repair rather than a replacement
What to know first
- A dial gauge should be checked for accuracy every year — most extension offices do it free, and most owners never go. A weighted gauge needs no calibration at all
- Presto does not publish a base diameter, so you cannot check it against the NCHFP element rule without measuring the box yourself. See will it fit your stove
- Rated for burners of 12,000 BTUs or less, which rules out most outdoor propane burners and some high-output gas ranges

Presto 23-Quart Induction Compatible Pressure Canner (01784)
The only full-size consumer pressure canner with a manufacturer statement that it works on induction, and Presto makes the point by excluding every other canner it sells by name. Heavy-gauge aluminum with a stainless steel-clad base, the standard seven-quart load, and it doubles as a boiling water canner.

What works
- The only canner in this category whose manufacturer puts induction compatibility in writing. Presto states plainly that apart from this model its pressure canners do not work on induction ranges, which is a far more useful sentence than a listing keyword
- Takes the same 7 quarts or 20 pints as the standard 23-quart and doubles as a boiling water canner, so on a cooktop that rejects nearly every canner this one pot still covers both methods
- The stainless-clad base is not induction-only. It heats on gas, coil and smooth-top too, so the canner survives a move to a different stove
What to know first
- Presto cautions that it may not work on all portable induction ranges. The company tested one specific portable unit, so a portable unit you already own is not a safe assumption
- Still a dial gauge, which should be checked for accuracy every year. A weighted gauge never needs it, and there is no induction-rated weighted canner to switch to
- Rated for burners of 12,000 BTUs or less, and Presto tells you not to use it on outdoor LP gas burners at all

Neither escapes the dial gauge
Worth being clear, because people sometimes assume the newer model solves it: both are dial-gauge canners, so both need the accuracy check the NCHFP asks for before use each year. If you wanted to avoid that entirely, neither of these is the answer — the weighted-gauge 16-quart is, and the trade is set out in dial gauge vs weighted gauge.
Both also share the same parts ecosystem, which is a genuine advantage of either. Sealing rings, gauges, regulators and racks are all listed by Presto against the canner's stock number, so a decade-old canner is a repair rather than a replacement. See pressure canner replacement parts.
What neither of them solves
Presto does not publish a base diameter for either canner, which is the same gap the whole range has. That matters on an electric coil or radiant range, where the NCHFP's rule is that the canner should be no more than 4 inches wider than the element it sits on. With no published figure you cannot check either model against your element without measuring the box when it arrives.
Presto's own heat-source guidance does give a working number — it advises matching an element to the canner's 8- to 9-inch base, and suggests an 8- to 10-inch heating zone for a portable induction cooktop. That is more than the product pages offer, and it is the closest thing to a diameter either canner comes with. Run it through will it fit your stove alongside your own element measurement.
Both also carry the same 12,000 BTU burner limit, and Presto tells you not to use either on an outdoor LP gas burner. So neither is the answer if your plan was a propane burner in the yard — that route and its constraints are in portable burners for canning.
The dual-purpose capability is the same, and worth using
Presto states both models double as boiling water canners for fruits, jams, jellies, pickles and salsas. This is genuinely the best argument for either canner over a cheaper water bath pot, because one purchase covers both methods and every jar size the canner is tall enough for.
Worth noting the contrast with Presto's 16-quart, which Presto states is not tall enough to cover quart jars with the required inch of water and is therefore a pints-and-half-pints pot for water bath use. Both 23-quart models are tall enough, which is a real functional difference between the sizes rather than just capacity — and the reason a 23-quart is the one we would buy if it is going to be the only canner in the house. The sizing logic is in what size pressure canner do you need.
One caution specific to the 01784
Presto cautions that the 01784 may not work on all portable induction ranges. The company identified and tested one specific portable induction cooktop with it, and that documented pairing is the only one. So if your plan is the 01784 plus a countertop induction unit you already own, treat that as unverified until you have seen it power up — and read portable burners for canning first, because the portable-burner category has its own published constraints.
Buy by stock number, because the listings are confusing
This is the practical hazard of a one-digit difference. Marketplace listings for these two canners share photographs, reuse each other's copy, and sometimes put both model numbers in a single title. A listing that says induction in the title is not evidence; the stock number is.
Check for 01784 specifically, and check that the description mentions the stainless steel-clad base rather than just warp-resistant aluminum. If a listing does not commit to a stock number, treat it as the 01781 — because that is the cheaper canner, and paying the induction premium for an aluminum base is the one mistake here that is genuinely annoying to unwind.
It matters after the sale too. Presto indexes replacement parts by canner stock number, so knowing which of the two you own is what makes the sealing ring, gauge and regulator orderable years from now. Write the number down somewhere that is not the box.
The decision, in one paragraph
Buy the 01784 if your cooktop is induction, or if you expect to move to an induction kitchen within the life of the canner — twelve years of warranty is long enough for that to be a real consideration, and the canner is the harder thing to replace. Buy the 01781 if you cook on gas, an electric coil or a radiant smooth top, because on those surfaces the two are functionally the same canner and the 01781 is the cheaper way to own it — the full write-up is the Presto 01781 review.
