'… well made and solid …'
'At first these mini parallel rules look too small until you discover their intended use. At a push they can be used as a pair of traditional parallel rules, however they have been designed for transferring your lat and long from the scale on the side of the chart to allow quick plotting of your position. A clever adaption of a classic design brought together as a well-made and solid piece of kit.'
'… a fantastic piece of kit …'
'The Paralock is a fantastic piece of kit. It is compact and well-built, makes GPS fixes a doddle and offers several advantages over a “conventional” set of parallel rules, such as the ability to quickly lock the rules to stop them expanding or contracting.'
'All in all, the ParaLock is refined and well thought out so that it is a joy to use. I have no doubt this is a tool which will spend most of its life out on the chart-table!'
