In the recent thread about the dangers of free diving I was surprised to encounter a degree of scepticism regarding the use of non-human surveillance techniques. With this in mind Lankyman Laboratories have been working hard to come up with a practical and effective solution: the Dynamic Underwater Monitoring Probe (DUMP).This has been rigorously tested in outdoor conditions and initial results are very promising.We are now taking orders for the inevitable Christmas rush. So, if you're worried about blocked passages just take a DUMP!
