The 300-meter Reel is designed to hold the cable for TROGLO crawlers securely and serves as a convenient mounting point for the LCD screen and keyboard. It is offered in both powered and manual options. The powered reel automatically retracts the cable for ease of use, while the manual reel requires manual retraction. The reel efficiently organizes the cable by winding it onto the drum and also provides a mounting point for the crawler's battery power and the power source for the powered reel.
