TriggerFish ROV Kit with Thrusters and Tether (Rev 4) (Unassembled)

Detailed assembly instructions (Detailed assembly instructions) are available for the Triggerfish kit, including video lessons, classroom activities, and many more topics here.

The SeaMATE Triggerfish Kit is designed for 15 amps. Modifications that increase the ROV's overall amperage above 15 amps may require certain components to be modified as well. See the assembly instructions for additional information.

If you're not sure where to start, take a look at this handy side-by-side comparison of the SeaMATE ROV kits.

The Triggerfish is an easy-to-construct ROV kit that moves from a switchbox controller to analog joystick control of four motors. The Triggerfish ROV kit consists of a control system, wires to receive and deliver power, and thrusters (motors, propeller adapters, and propellers). A frame is not included in the kit, but frame materials can be purchased from your local hardware store.

The control system is housed inside a compact, Seahorse brand protective equipment case. Two joysticks make piloting the Triggerfish ROV easy and logical. Each joystick controls two motors: one joystick controlling forward/reverse and turning, the other joystick controlling up and down, and sideways movement. The joysticks and control boards on the Triggerfish allow speed control; nudging the joystick forward provides slow speed, while pushing the joystick fully provides full-speed movement. The Triggerfish comes video ready (video system sold separately) with two video input channels and easy power out for monitors and cameras. A volt and ammeter, along with multiple LED indicators, display vehicle status and make the Triggerfish easy to troubleshoot. Modular connections mean that Triggerfish control boxes and vehicles are interchangeable.
