Why this gift works

The Carson RimFree LED Magnifier (RM-77) is a handheld 2x magnifier with a rimless rectangular acrylic lens, 4.7 by 2.7 inches, and a built-in white LED. It runs on three SR1130 button cells, which are included, and comes with a soft carrying case and a limited lifetime warranty. It measures 9.3 by 4 by 1 inches and weighs 5.6 ounces.

History buffs spend a lot of time with small print: map labels, footnotes, old letters and family records. A wide lighted magnifier reads a full line at a time, which makes it a small, genuinely useful companion to a history gift.

Who is this gift for?

Great for

  • A reader of atlases
  • A family historian
  • An older history buff

Think twice if

  • They collect coins or stamps
  • They want a glass lens

The catch

At 2x it is not strong enough for coins or fine engraving, the lens is acrylic rather than glass, and it uses less common SR1130 button cells.

Skip if they need strong magnification for coins or stamps.
