On an earlier thread we thought it might be a good idea for members to post photos of any old, antique, or unique traps that they might have hanging around. We can then hear from the veterans (old timers) on the pros & cons of these traps. These old Jump are all I have to post, but maybe it will start things rolling. Moderator Note: It is a little hard to tell the size of these Victor Jump traps, but my guess is that they are #1's. Another name for this type of trap is "Under Spring", which IMO is a better name, since these traps don't really do any jumping. The main problem encountered in using this type of trap, however is that when it fires, it does tend to flip slightly in the direction that the spring is traveling. Therefore, it is important to have the animal coming to the trap from the side where the chain is attached. The smaller sized Victor Jump Traps (smaller than #4), for the above reason never seemed to be as effective as a long spring trap. Also, once coilspring traps became popular, then this Jump (Underspring) design was discontinued, because a coilspring trap is just as compact and doesn't have the directional problem inheritant in a Jump trap. Also, you can see that the pan is just too large for the jaw spread and this also contributed to a lot of empty sprung traps. Wanna kill these ads? We can help!
