Boris Wilkins –
These indicators are much easier to cast than the plastic ones I used before. The EVA foam floats better and stays straight in the water. I’ve used them in both still and moving water and they hold up well without cracking or leaking.
Simon Wilson –
The color variety is nice and the assembly is simple. I just twist the nut and it fits perfectly. The floatation is better than expected, especially in light currents.
Anthony Watson –
I’ve had several sets of plastic indicators that broke or leaked, but these have held up well. No dents or holes after multiple uses. The lighter weight makes casting smoother and more accurate.

The indicators work well with my 3/4″ leader. The notch holds the leader securely and the nut tightens easily. I appreciate the biodegradable material for the environment.
