Daiwa CN-460M VHF/UHF Cross Needle SWR Power Meter
The Daiwa CN-460M compact cross-needle meter displays both forward and reflected power over a frequency range of 140 - 450 MHz in ranges of 15/150 watts forward and 5/50 watts reflected. Accuracy is ±15% at full scale. SO-239 jacks. These meters include a mobile mounting bracket and meter illumination.
Please see other models in chart below. They look the same but have different frequency coverage, power capacities and jacks.

140-450MHz Compact Cross Needle SWR Meter. 15/150 Watt ranges with illuminated meter and SO-239 connectors.
Purchased my CN460M from Atlantic Ham Radio (Now Radio World) in Ontario. It was the first cross needle meter I had used and right away, that sold me on that type of needle movement. I liked the idea of a backlit display and it came with a mounting bracket as well which makes it a very stable unit when using RG-213 or similar coaxial cables.
As for accuracy, it is every bit as accurate as a certifiable meter such as a Bird or Celwave which I compared it to when a member of our club was kind enough to provide when we did some antenna work at our club's repeater, he is a manager of a mobile radio shop so he had this at his disposal.
I compared it to a Celwave, not sure of the model and it was close enough to the readings on the Celwave meter, e.g 1.5:1 VSWR, the Diawa read a little lower, about 1.4:1. Not bad, at least you know that your antenna and feedline are within spec.
A great meter that don't cost as much as the Birds or Celwave meters, but will give you comparable results.
