Hints, Tricks, and Tips to get the most out of your White’s Surfmaster PI and to help with preventive Maintness
Whites Surfmaster PI Lid Tip
Those of you familiar with the Whites Surfmaster PI will notice that units require a greater effort to clamp the lid. This is due to a change in hinge assembly configuration. The belt mount plate is now thinner and under the hinge base between it and the case which acts like a shim. Now you with older units (that have the curved lid and rectangular pre shaped O-ring) –DO NOT PUT YOUR OLD BASE PLATE UNDER THE HINGE!! If you do so something will break. I have in the past when I found the hinges had stretched used shims made from a plastic gallon milk bottle which is thinner than a credit card for example. Back to the new configuration–In another post I described the best method of opening and closing the box. This is the best way to deal with the more force needed and to ensure the lid stays centered on the box. Basically you do it with the unit upside down and operate both hinges at the same time.
Surfmaster PI O-Ring Tips
Maintaining the O-ring and it’s two seating surfaces in a pristine clean condition is the single most important thing in getting a good seal. There are some other factors that can also aide in the sealing. First of all don’t overstress the hinges–be sure the lid is aligned properly to the case and close the two hinges at the same time. The lid on the later models is bowed up in the middle to enhance seating on the ends. You can spot hinge relaxation by watching the side of the box to lid relationship. Under the hinge on the box side is a thicker area and the spot to watch is the gap between the top of this and the lid. Also you can see a line along the side of the box top area which will show the center of the lid moving up. Here’s a good way to handle opening and closing the box: If wet, dry the unit off with towel or t-shirt, etc. Place the unit on a clean surface (towel) upside down. Dry yourself off if wet so you don’t drip into the box. Unlatch the hinges and lift the box off the lid–the advantage at this point is that residual water on the lid edges won’t fall into the box. Roll the O-ring out of the groove with your thumb. Clean both seating surfaces. I keep a spare O-ring with my replacement battery pack which I now install. If an O-ring is kept clamped down for a long period it tends to take a flat set and will not readily expand if clamping forces relax. So if laying up the unit for months or so–don’t keep it clamped on the O-ring. Now with the unit upside down it’s easy to lay the O-ring in the groove and get the box centered on the lid. Move the box around until you feel it center, you may need to use one finger to keep the battery pack in place when initially putting the box on the lid. Slowly raise both clamps and watch the lid centering, sometimes you’ll feel it move into alignment. Finish raising the clamps together and then look closely at the lid to box area. Grease is not required on the O-ring per the manual, however, if done correctly, is of no harm. Basically grease allows relative movement between the box and lid when clamping without bunching the O-ring. Two points to ensure are that the grease is neutral and won’t degrade the Whites Surfmaster PI O-ring, and extra care is given to cleaning as the grease will attract debris. Bottom line is that you should realize that your close attention to detail can make the difference.
Whites Surfmaster PI Tips for Hot Rocks
Went down to Waikiki to look for a lost ring and as often happens didn’t find it, but found a Hawaiian engraved ladies band which had been there for a long time judging from the coral growing on it. It was down alongside of a hot rock which probably prevented it’s being found. Interesting point is that you can get hot rock signals when the whole loop passes over the rock–flip the loop up 90 degrees and use the edge of the loop (bounce it up and down an inch or so for motion) and use the ~ 1/2 ” wide sensitive band that comes off the edge of the loop which will not signal on the rock, but will see a coin/ring about 6″ deep. The edge band is also a help in pin pointing in rocky messy areas–only need to angle the loop up 45 degrees and bounce it in toward the target. Another good technique when initially locating a target is after the signal, stop off to the right side and then moving the loop away from you and back toward you sidle it back to the target. When it signals the target is at or off the edge of the loop a few inches (depending on depth). This is handy if you can’t see the loop because when you slide your foot out and touch the left side of the loop the target is below your toes. Works the same if you’re at 45 degrees also.
Tips for Deep Surfmaster PI Targets
Haven’t seen much of the water since mid summer due to bouts of surgery and holiday travels. For those of you in the grips of winter it’s probably hard to imagine that we hunt in the water year round over here. Any way, went out and did a shallow water hunting twice this past week and in each of the two hour swims came up with a gold and silver ring both times. The first time was in 3-4 ft. surf wearing 35# of weight to keep my feet on the bottom. The waves generally stir stuff up and the $6+ of change included a silver 50 cent piece and a real thin green silver dime, a watch that took a beating and quit ticking, plain silver band, and a man’s 14K band with small diamond. The next trip was a different beach, same water conditions, but this time due to poor water visibility worked the waters edge. The face of the beach was being pulled into the water and all targets were deep in loose sand. Pushed the loop down into the sand troughs and walked a straight line parallel to the beach edge. The trick here is by pushing the Surfmaster PIs loop down tight to the bottom and moving smoothly the threshold is steadier and you can hear the faint signals better. The rate of movement is also important, going to slow is the worst mistake. The results were a silver dolphin ring and a ladies delicate gold filagree ring with a marquis shaped emerald stone. Also, if wind noise distracts you, cover the headphone flood and drain holes with plastic band aid tape. This can be peeled back and stuck alongside the holes to allow flooding and reused a few times.
