It allows the Labrad unit to be positioned close to the shooter and within reach, instead of out at the end of the barrel.
No longer a need to get up or wriggle around when the unit fails to trigger or track a bullet, or you need to change bullet parameters etc.
A total of 110 shots from two different rifles (and bullet weights) triggered and tracked 100%.
I tried it mounted underneath the fore end of a 6BR using the supplied bracket, and simply lashed to a bipod leg of a 6.5x47 using the velcro tape. It worked every time.
It's the first occasion in the years i've owned it that the labrad triggered and registered MV of every single shot taken during the morning.
And the colour matches!
