I have been using a Walkstool for a number of years. Used it today and yesterday. It is now blowing with gale force wind and raining so not tomorrow! It is very light and can easily fit into backpacks such as the one I used today (dark green color item in second pic). The walkstool went in along with my underwater housing, toolbag, bundle of 10-meter-long waterproof cable, and bug proof shirt. One shot shows my remote monitor on the stool with my camera pole set up in the lake in the background, the other I am sitting on it facing away from the lake - there are willows to the left and right and just above the frame. With me hunched over a bit I could see the monitor screen - not easy outdoors.
ps The Z6 used to take these pix traveled in the soft bag that (upper right) that in turn was in the Billingham bag that I used also for the book and monitor. I carried the camera pole in my hands - ready to wack a bear's nose if needed!
