What is the MSRP for the Signal? It has some intriguing features so that it might replace my Wave for outdoor pursuits. The MSRP for the Tread has tempered my initial enthusiasm. I will probably wait for a knockoff watch band. The cost of the Tread would be better spent on a PLB (or two).

I have carried a Ltool for the last thirty years and I have benefited numerous times, but the original PST was really fine. With modularity and a locking knife blade, at no great increase in weight or bulk, it would approach perfection. It is still my tool of choice in some situations.
