I suppose since I touched on it in the Long Range Hunting forum, I could go into a little detail for those that are interested.
I've picked up a Skywatch (the brand) Meteos (the model) to try my hand at learning to compensate for the constant, unpleasant, screaming, Wyoming Wind.
The unit is a little smaller than the large Jon-E hand warmer and will easily fit into a shirt or coat pocket. There are only 2 buttons to contend with that are marked on the front, but sealed off from the elements. There's a removable top cap that covers the impeller blades to protect them in transit and the cap has a cheezy compass molded into it.
The unit gives max wind speed and current wind speed as the default, but if you push one of the front buttons, you'll get average wind speed as well. There's also a temperature readout and a wind chill function that really helped out when I wanted to feel sorry for myself and how cold I felt.
The unit has a tripod mount in the bottom and a large, easy to read display. I set the tripod up slightly higher than the gun and several feet away (on the up wind side) to try to get as uncontaminated of wind readings as possible. All in all, I'm very confident that with time and practice, my wind doping will impove as a result of having this along.
I also mentioned a model that was made by/for Radio Shack.
I don't belive it's currently being made, but what a nice little unit! This unit doesn't require being pointed into the wind either. There's an arrow on the top that you can point the direction you're shooting and a sort of digital clock face on the front of the unit that tells you which direction the wind is striking it from in relation to where it's pointed with the compass being divided into 16 directional possiblities. ie, west-southwest or south-southwest vs straight southwest. This is definately a hand held unit. There's no tripod mount, and even if you rig one up, the display is too small to read from much more than arms length.
At this point, I'm using the wind meter to get accurate wind speeds, judging wind direction and then pluggin the info into my laptop (PCB-18) for a shooting solution. Mostly I'm playing at this point (today it's about 19 degrees with 25mph winds) but I anticipate gophers trembling at the sound of my footsteps (4 wheeler, truck) by the end of summer.
Take care, Coyoter
