Stereo Test Worth 4 Dot Near Attachment

Compared to conventional Worth 4 Dot Flashlights, the Worth 4 Dot Attachment lets you avoid cumbersome flashlight units using D Cell batteries, which can leak and are not rechargeable. Rather, the Worth 4 Dot Attachment uses the transilluminator or muscle light attachment which everyone has and keeps recharged.

Red/Green Anaglyph glasses required.
