Shooting sticks. . . .

The spike on the point is designed for soft ground so if that is where he is likely to be, yes.
Alternatively you can get a walking stick which will open out to provide a little perch which is the same sort of idea but with 4 (?) rubber tipped feet.
Paw got his from the very smart umbrella and stick shop near Holborn - James Smith & sons, 53 New Oxford st, WC1 1BL. Google them.
Worth investigating . Good luck.

What naw said.

My bil has dreadful arthritis and uses one which I think he got from the National Trust. I'm sure if you Google there will be lots.

Maw, not naw - sorry!

The sort described here which provides an actual seat will be more comfortable and stable than the traditional shooting stick that I used for years but which I doubt I could sit on for long now.

Thanks-you see I knew we wise Grnas would know!

Grans!!

It's a good idea to practice first. It's a bit of a knack getting it at the right angle to perch on and making sure your balance is OK.

They can be very unstable.

You might find one in a charity shop that will be cheap enough to use as a try out. If the stick works out you could then buy a new one.

Coopers of Stortford, mail order, do a folding cane seat. £19.99. which is stable and comfortable and weighs very little. I have found it very useful.

Thanks all-I had a look on NT site but not very impressed. Will give Coopers a go!
