HAMMERHEAD NEWS!

Version 5.3 Software is NOW AVAILABLE!

Version 5.3 contains the new Set-Point Maintenance Algorithm introduced in Version 4.0 which significantly increases the accuracy of your loop ppO2 (to within .01 of an ATM in some cases!), PLUS the Diver now has FULL CONTROL over their Hi/Lo Gradient Factors! There are 5 pre-set GF Values found in the new Conservatism Menu, plus the Custom Gradient Menu for Advanced Users -

NO OTHER DIVE COMPUTER ON EARTH OFFERS THIS!

To upgrade to 5.3, contact us directly!

Check Out the NEW Rev. B. Electronics - Now powered by a SINGLE "AA" Alkaline Battery!

What's the difference? : The Rev. B. boards use an improved power supply which allows us to use a single AA alkaline battery. In our tests, this battery lasts a LONG time - how long we are still determining - it's a tough call, estimating battery life, since you have to pick a certain amount of Solenoid firing over a given period of time, and try and estimate how often the diver will activate their backlight, etc, etc. But right now, this appears to give us well over 12 hours of actual dive time on a single AA battery. That is tremendous, even if we do say so ourselves.

We've also added a fairly large capacitor to go along with the new power supply to level out the voltage sent to the Solenoid during firing, even when your battery is running low (like less than a volt, believe it or not!).

Hammerhead Running off of a single Energizer!

One other difference between the Rev. A and B is that Rev. B has a Super Capacitor built into it, which keeps the unit "alive" while you change batteries (provided the unit is asleep at the time). In our tests, we have consistently been able to remove the battery for 5 minutes and retain all deco, depth, and surface interval time data. In fact, it retained the data even after 10 minutes of "battery withdrawl" We even managed to keep the unit running "headless" for 45 seconds while it was still "on", which was kind of eerie - disconnect the battery and it refuses to die, sorta like a horror movie... Of course, this is not recommended!

This will provide the diver with huge benefits - not only in cost savings over any other CCR controller in the world, but also in the sheer convenience of being able to find a battery to power your unit anywhere on Earth - usually for pennies.

Another first for the Hammerhead!

Push-Button Maintenance

A note about maintaining the push-buttons in your Hammerhead Wrist Units:

When we were designing the Hammerhead, one area which we concentrated on was the Push-Buttons.

Every diving system that uses any kind of switch has to solve the problem of how to activate those switches in a salt-water pressurized environment. We went through lots of revisions, and make all the general mistakes that everyone else does when trying to tackle this problem. In the end, we came up with a system that is not only simple, but dare we say "elegant?"

The Hammerhead Wrist Units utilize five elements to make them effectively work under any circumstances:

1) Push Button with 1/4" Hex sides

2) Outer Retaining Boss broach-cut to match Hex of Push-Button

3) Stainless Steel Spring

4) Rare-Earth Magnet

5) Proximity Switch

Numbers 1-5 above all live OUTSIDE the sealed electronic compartment. The Proximity Switch lives INSIDE behind a bulkhead, protected from the outside environment. The magnet is sealed inside the Push Button using our own secret recipe for keeping a magnet safe in salt water.

When you depress the push-button, this magnet comes in close proximity to the switch (hence the name "proximity sensor") which then closes the switch and tells the main CPU that you just pressed the button. Since there is no access to the internal electronics, this area does not have to be sealed, which means that you, the diver, can take it apart and keep it clean.

Now, just because the magnet is sealed doesn't mean that it is impregnable - remember, it is sitting inside a different metal (Stainless) and immersed in Salt Water - what is generally called a "bi-metal reaction" can take place - and usually does.

Here are some pictures:

Here you can see some corrosion visible through the clear housing.

Lets go inside:

Using an adjustable wrench, we unscrew the button and boss out of the wrist unit.

We're then free to remove the whole assembly.

You can see that even the spring (which is made of a different lot of stainless than the push-button) can start to show some corrosion if not taken care of.

What we suggest you do to maintain your Buttons in tip-top shape is to unscrew them after a dive using a tool that will adequately grip the Hex of the button, rinse them off with fresh water, and then lube the whole arrangement up with some Silicone.

Here we are cleaning out the whole pocket with a Q-Tip.

And now it's all nice and clean again!

With proper maintenance, your Push Buttons should last forever. The spring size is also a standard part, which is 316 Stainless 1" long, .25 inches in diameter, with .029 wire.
