There is a lot of controversy over "Pulse Delay," and its importance to depth and small target sensitivity. Unfortunately, most people don't understand that a setting of 10us pulse delay, is very noisey and unsteady on wet ocean sand. So even though you may be getting more sensitivity to smaller targets, you might not hear them.
Now, move your coil from the wet sand and into the water and you will have to increase your pulse delay to at least 15us to smooth out the threshold. By the time you have reached a depth of five-feet in saltwater, you'll need a pulse delay of about 20us.
Those who fault the Tesoro Sand Shark for running a 19.5us pulse delay, instead of a 15us pulse delay, claiming it is less sensitive or lacks depth compared to other machines costing twice its price are welcome to their opinion, but if you are a water hunter and have used the different machines like I have, you know better.
The pulse delay must be coupled with power to the coil, and circuitry that filters and reads the return signal. The performance of a machine is NOT based soley on pulse delay. That is my opinion, and why I think I would rather have a set pulse delay of 20us, than 15us.
