I'm a paragliding pilot with P4 licence and I've purchased a 2nd-hand FLYMASTER B1NAV flight instrument for XC flights – mainly for logging the flights (route, distance, max. speed etc). It is an Altimeter-Variometer-GPS combo. As you know, these devices warn the pilot with beeps during climbing and sinking.
I'm using the device for a couple of months but I recently noticed an interesting thing: When I enter the thermal I first feel the climb with my harness and risers. But the device starts to beep with a delay of 1-2 seconds.
Is this normal?
I know it's an old and discontinued product. I've looked into its manual, but couldn't find any info about the delay. I don't want to rate this device as "broken", but I cannot be sure.
