The MH4 provides brightness for fishing and hunting – now also available with red-light for better night vision. With just a few easy moves, you can turn it from a head lamp into a multi-purpose lamp. The MH4 draws its power from either the supplied rechargeable battery, which is easily charged by the Magnetic Charge System, or from an AA battery. The Advanced Focus System allows rapid focusing and the stepless swivel mechanism directs your light exactly to where you need it.
