1 Introduction

The TH-Series handheld thermal camera enables you to see
easily in low-light conditions or even total darkness.

Typical uses for TH-Series cameras include:

• When you have the TH-Series camera on deck,
at night in dark anchorages you will be able to see your
surroundings, even when it is cloudy and there is no
moonlight or starlight.

• See clearly in total darkness—unlike other night vision
systems, TH-Series cameras require no light at all.

• See logs, rocks, land, and other hazards that radar
can miss.

• Navigate with confidence at night knowing that you can
see harbor entrances and waterways in total darkness.

method of viewing thermal imagery; black hot can often enhance
contrast of certain objects or provide better visual perspective in
some conditions. When switching between palettes, the
appropriate icon is displayed for approximately 3 seconds.
