Robust ‘fish-finder unit’ designed to withstand repeat ‘crash tests’ and most challenging elements

Then let it sink 20 metres before raising it to a controlled position just below the surface for 4 hours, whilst it transmits underwater images direct to your phone or tablet. The brief also dictated; repeatable use over a number of years, and incredibly, it should weigh less than 100gms.

The brief read like a military specification

The durability of the plastic injected case being cast over 100m and landing on water at speed was a key factor in the success of the ‘soon to be fisherman’s gadget’ now in daily use by top anglers. Working closely with the designers the iterative design and development process resulted in many rigs and prototypes being manufactured and tested over thousands of hours of hardcore fishing. All this to prove and perfect the difficult issues of protecting the electronics and maintaining watertight seals, whilst providing internal access for battery charging.
