Why Do Range Testing?

It is imperative that range testing be integral part of every study to ensure you get the optimal results from your VEMCO equipment deployments. This testing should be carefully planned in order to produce relevant results and should focus on areas and conditions of planned deployment.

Detection range of a receiver is highly dependent on:

• Noise levels (caused, for example, by weather, boats, marine life, etc.)
• Absorption which depends on conductivity, temperature and depth
• Wave bending produced by temperature gradients and other effects

All of these factors can vary significantly from one location to another and with time in a particular location and can impact range for some signal paths and, in some cases, even produce shadow zones. This needs to be taken into account when installing an array of receivers with the objective of detecting all passing fish. View our Range Testing Introduction and Range Testing Tutorial videos for more information on the value and importance of range testing.

A preliminary version of our internal Range Test Software is also now available for customers to aid in analyzing range data. Please visit our Range Test Software page to download.

Please contact your VEMCO Sales Representative for advice and assistance for setting up range tests.
