It is true, I am pleased to report that I recovered my landing net by trawling the bed of the pond with a 7oz uptider grip weight, So the trip hazard has been removed and no fish were hurt during the exercise. The net has since been used for its intended purpose.

Hi Morgan, I know very little about them but just had a look via google and a new one with about 20min flight time, home return fitted with a camera is about £550. not excessive if it works and expels the birds. Would need to take the advice of an expert but probably the more you pay the better the device.

Many thanks for the replies and I hope the markers work.

What a great website. Well done all involved.
