I hope there is someone that can help with this. I found the work of breathing horribly high on my first dive, and on checking the IP it was 130. Now from the "technique book", I notice all other Beuchat regs have an IP of 140, and in fact the Dive rite Hurricane has an IP of 145. Having readjusted the IP to 140, it breathes beautifully. Strangely this did not affect the cracking pressure. Could someone supply me with the service manual, or just confirm the pressure?
Thanks in advance.
