<p>[QUOTE=&quot;desertgem, post: 715167, member: 15199&quot;]I have a B&amp;L scope similar to this one. It is adjustable from 7x-30x as it comes. A secondary lens of 0.5X attached to the objective makes it 3.5X-15X.</p><p><br /></p><p>The ability most are not aware is that this is a &quot;stereo&quot; microscope. With the 2 eyepieces spaced correctly, the image viewed has depth perceived, even at high power. Loupes only&nbsp; allow 2D vision, so the coin must be tilted back and forth to see if a structure is raise or inclused. You might not be aware of doing this, but you are. After much experience you have learned to tell, and might think all can do so easily, but many may still have problems. With a stereoscope, it is apparent.</p><p><br /></p><p>Loupes are a necessary piece of equipment, because you don&#039;t want to cart&nbsp; a scope to a coin show <img src="styles/default/xenforo/clear.png" class="mceSmilieSprite mceSmilie1" alt=":)" unselectable="on" unselectable="on" />&nbsp; but if you find a piece of plastic such as used to hide the edge of a 3/4 in. plywood or particle board shelf, you can lay 10 coins down and push all across the scope stage, one at a time, and all of the time is used to look at the coin, and not twist it around under a loupe.</p><p><br /></p><p>Once a variety hunter uses a stereoscope, I think very few would want to give it up.</p><p>IMO.</p><p><br /></p><p>Jim[/QUOTE]</p><p><br /></p>
