Re: Triggering the traps

We don't especially want to trigger them separately other than they are separate traps and we get a little more out of the traps if both are locked down. If we have to use a pencil vertically it requires two hits, if you can lay the pencil across them of course that works but don't think that is leg...

Triggering the traps

All, I ask this question somewhat sheepishly ... if you use two traps is it permissable to lock both traps and trigger both (one at time) with the pencil to get the device started or does one have to be already released held back by the first ... eg: you are allowly allowed to have one trigger?
