The Dino-Lite HDE-01 handle is a lightweight aluminum handle which provides a more ergonomic and natural grip when using the Dino-Lite. It is most commonly used as a grip for the Dino-Lite EarScope, but is also suitable for other applications where a vertical grip is more useful. The sturdy, lightweight aluminum makes this HDE-01 handle a good add-on for the Dino-Lite EarScope or any other Dino-Lite model.
