Well, there are two models, and I got the one that goes from 20x to 100x. I wish I had gotten the that goes from 10X to 50X because at 20X a newly hatched fry doesn't fit in the field. Here is the info from the web page at
http://scientificsonline.com/product.asp?pn=3081733&bhcd2=1089478038


The DigiScope 150 features a 10x to 50x manual zoom lens that provides on-screen magnification of 42x to 210x. The lower magnification provides a larger field of view.
The DigiScope 300 features a 20X to 100X manual zoom lens. In both cases the zoom is seamless, providing exceedingly crisp images and an exceptional 4mm depth of field. Because of the camera's high frame rate (~10fps) focusing can be done in real-time.

Go to e-bay and do a search for the QX3. This one, by Intel, covers a wider magnification range, and has been raved about by those who got one. It is being dumped, in quantity, by one company at $47.95, and others are even cheaper.


Instead of smooth zoom, I think it has fixed 10X, 60X and 200X magnifications. Fixed may even be better for measurements against a scale.

Even if it has less basic capability, the $50 price range is more in line with the hobby pocketbook, I expect. Ask Tim Addis, who just got one and seemed very happy with it.

For a comparison you can take, with a grain of salt, the one by the folks at Science Kit/Digiscope at:
