I just received my SAP(Shetland Attack Pony) and have posted some pics here http://tinyurl.com/2cvppc it is a sweet device and will make the cave survey SOOOO much more comfortable for the instrument reader. The fact that you can place the SAP directly on the station and hold at any angle will also in my opinion give more consistent results over a broader range of skill levels. Total cost was about $580 U.S.
