Amazing thermal! Dual lens system lets you easily switch between the 25mm lens at 2x base and the 50mm lens at 4.5x base. This lets you zoom in naturally without degrading your image with the digital zoom. (Which this also has.) Look up the reviews. This is the best. Also has the rechargeable and changeable batteries. Giving you 10 hours per battery and 20 hours combined with the two included batteries.
Will consider partial trades.
