Marine Miles Reward Miles

Our Marine Miles Program rewards our customers with rewards points earned on all purchases. Our rewards program is simple and free.

Marine Miles can be used to apply a discount to your final total. For every pound that you spend you will automatically receive 5 Marine Miles that can be easily redeemed during the checkout process. The more Marine Miles you collect, the bigger your discount. Every 200 miles you accumulate will earn you a £1.00 discount.

Unlike other rewards programs, you're automatically enrolled in our Marine Miles program when you create an account and log in (This is so we can keep track of your points). No sign up forms to fill out and best of all, our Marine Miles program is absolutely FREE! Your points are automatically accumulated for you beginning with your very first purchase and displayed at the top of each page for easy reference.

Please note that you must have a minimum purchase of £10 in order to redeem your Marine Miles. When redeeming reward points, your total discount cannot exceed 40% of your shippable order total before shipping. Any leftover points exceeding the 40% discount will still be available for future purchases. Marine Miles are not transferable.

    Product Details

    The NASA Stingray Echo Sounders come in a slimline case with an easy to read extra bright LED display on a 4 inch dial. It has a dual audible alarms for shallow and deep water which can be set to give two ranges either 1-25 metres or 1-100 metres, which are simplicity itself to operate. It comes complete with transducer and stirrup mounting bracket and only require connection to the ships 12 volt power supply.

    How They Work:
    Very simply, they make a noise and measure the echo. Knowing that sound travels at 144 metres a second through water allows us to calculate the depth by measuring the interval between the sound being made and the echo being heard. The NASA Stingray Echo Sounders have a transducer with a high quality Lead Zirconate Titanate Piezodisc crystal which creates ultrasonic 'sound' pulses at a frequency of 150 kHz (imperceptible to the human ear). These pulses pass through the water and bounce back off the bottom. The returning echo pulse is then sensed by the transducer crystal. On these rotary flashing LED type sounders, a pulse is generated as the LED flashes at the 12 o' clock position. The rotor arm is calibrated to run at a speed whereby when it flashes on receiving the returned pulse this flash will be in the correct position on the dial to indicate the correct depth.
