The Rechargeable Eclipse Headstock Tuner delivers up to 24 hours of tuning on a single charge. Using the included USB-C cable, you can easily power it up from any USB-C port. It features the same multi-swivel design, extra-bright LCD display, and convenient auto power-off as before — but now there’s no need to replace batteries. With its new rechargeable design, vibrant full-colour vertical screen, and simple clip-on functionality, the Eclipse offers outstanding value for players of all levels.
