Good device - Brunton ADC Pro Altimeter Barometer Compass ADC-PRO

If you looking to use this for long range shooting then i would suggest a separate wind speed device as the brunton doesnt pick up wind speed accurately and will not pick up slower speed wind, possible due to the tiny propeller size and drag inside the device.
Pros: Has everything you need
Cons: Unable to read wind well
