Harbor Freight has a $7 pressure mat (part of a simple alarm) that can be used instead.
But Spirit is selling theirs for $4.99 so cheaper than Harbor Freight, plus I would assume Spirit's would work easier with their props (i.e. less modification) then Harbor Freight's would... I was thinking of tryin get Harbor Freight's one previously, but Harbor freight also doesn't seem to be able to ship outside of the U.S., at least their website doesn't allow for non-USA orders.
So happy to see that Spirit is now selling these cheaper than Harbor Freight, plus they'll ship to Canada now.
I just ordered 3 of them. I want to see if I can use them both for my Spirit animatronic devices, and then also see if I can attach it to my picoboo's to run some of my pneumoic props as well. I'm just not sure if the "try me" wire is the same as the wires that go into picoboo devices.
Also these pad's may not be the same as the pads that the spirit stores use for their own props. Just cause the picture isn't the same, I mean the spirit pads have the spirit logo all over them and looked different to me (maybe smaller?) hard to tell from the picture. The spirit website doesn't have much of a description and doesn't have any measurements. But at the $4.99 price it's worth it to order a few and just see how useful they turn up to be.
