I got lucky! Time Owned: 0 to 3 months.
I was impressed by the reviews below. Recently I found several CN-720Bs on eBay, One had a broken meter bezel. The other one looked great. When I received it I was amazed. It looked (and works) like brand new.
Although I have several other watt meters, like Bird, LP-100A, Drake, etc, this one is awesome.
Matches the Bird and LP-100A exactly!!!

Awesome meter Time Owned: more than 12 months.
I have two CN-720B's, first one from a seasoned ham, and second from an estate. My first one is just a tremendous meter, and the classic look fits with old gear and new. I bet it would really look great paired with old Heathkit or some National gear with their bluish tones. I borrowed a Bird meter, and the 720B reads only a hair different. The estate purchased 720B is wonky, and upon examination I found one of the old variable resistors to be cracked above one of the mounting pins. Now to find a proper replacement resistor and get this one in line as well! Highly recommended meter.

Very Good meter Time Owned: more than 12 months.
I bought this meter new in the early 80's and still have it. I keep it in line with my equipment and have never had an issue with it. When I had tube units and then solid state it still tunes both. Solid unit and always gives good readings.

Pick of the Litter! Time Owned: more than 12 months.
The CN-720B and other large-scale meters at the shack here work very well, indeed. Accuracy is all that can be expected, given the vagaries of amateur installations. The large size is readable from anywhere in the shack and the quality of the meter movements, themselves, is excellent. Daiwa was not the first to offer a cross-needle VSWR meter, however. Many years ago, TMC had a cross needle meter on their antenna tuner systems. Of course, given the cost and size, it was generally unsuited for amateur use.

One of the very best Time Owned: more than 12 months.
This is one big, weighty SWR/Power meter. I could be wrong, but I think Daiwa introduced the cross-hair style of auto reading meter to the radio amateur market.

I have had it for many years and it continues to be one of the most accurate meters I have ever used. The large display makes it easy to read, especially if your eyesight is getting a bit on the weak side, as mine is.

I removed the two 'feet' which push it up at an angle. I find the flat configuration more attractive and convenient. Particularly if it is on an eye-level shelf, The stainless-steel front panel may be a bit dated these days but so what! This thing is as solid as the Rock of Gibralter. Rather than use the calibration-type meter on my fine Kenwood TS-200 tuner, I put the Daiwa in line and ignore the Kenwood.

If you manage to find one used on e-bay or any private sale, snap it up. You won't be sorry.

Outstanding! Time Owned: 0 to 3 months.
This is a very high quality meter that covers 1.8 to 150 MHZ. Covers 3 power ranges (20w, 200w, and 2kw). This is definately one of the better Daiwa meters that were produced and very much sought after on the secondhand market today.

The only other meter worthy of 1st place and attention is my Bird 43.
