HC-SR04 Transducers spacing

HI Chaps

Quick question, at the moment the spacing between the transducers are about 10mm I need to move them apart to around 65mm.

Will that be fine? Will it effect detection? Will it effect accuracy?

Many Thanks.

It may affect very short range sensitivity, but I doubt it.

Ok thanks Awol, yes Im only looking to detect between 1 and 2 meters anyway so short range wont bother me.
