our NON scientific testing:
Configuration
Spitfire no external speaker approx 114 Peak* DB
Spitfire with SP108Z and internal speaker OFF 120 Peak* DB
Spitfire with FOXPRO TOA & internal speaker OFF 119 Peak* DB
Spitfire with SP55 and internal speaker OFF 119 Peak* DB
*Peak DB reading is the highest db reading recorded using a particular sound. It is not a indicator of audio quality or increased lethality.
All measurements were from 1 foot using sound #233 jackrabbit distress. Yes, we have a IEC651 Type 2, ANSi S1.4 type 2 compliant digital sound level meter.
4 new AA akaline batteries were used.
Do you recall the other details of the testing?
ie indoor, outdoor, call on the ground, sound meter in relation to the call same level or above, hard or soft surface.
I just bought a Spitfire and it doesnt sound very loud to me so if I could test in comparison to your 114db it would give me a idea of what I should expect.
Thanks
