Pinch flats

Hi all. New to the cyclocross scene. Experienced road racer but not done cx before this winter. I bought an entry level Focus mares and am enjoying the events so far. However with the wet weather I had to run softer pressures the last day and suffered a pinch flat which I'm told will happen unless I go tubs of tubless. Does anyone recommend a tubless tyre that would work with the DT swiss rims I have? I don't want to go into great expense of getting tub wheels etc at this stage.
